Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers Introduction For PowerPactTM H-, J-, L-, M-, P- and R-Frame circuit breakers see class 611 and 612 catalogs on the Schneider Electric website, www.schneider-electric.com. This catalog introduces legacy thermal-magnetic circuit breakers, magnetic only circuit breakers, and molded case switches. Most of the legacy devices are obsolete but will be in service for many years.
Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers Molded Case Circuit Breaker Types This catalog discusses the following types of molded case circuit breakers: — Thermal-magnetic, including current limiting circuit breakers — Magnetic only (Mag-GardTM) circuit breakers — Molded case switches • Thermal-Magnetic Molded Case Circuit Breakers Thermal-magnetic molded case circuit breakers are the most common overcurrent protection devices.
Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers • Magnetic Only Circuit Breakers Mag-Gard magnetic only circuit breakers comply with National Electrical Code (NEC) requirements for providing motor circuit protection when installed as part of a listed combination controller having motor overload protection.
Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers Internal Operating Mechanisms The following mechanisms allow the circuit breaker to operate: — Thermal trip — Magnetic trip — Push-to-trip button — Shunt trip — Undervoltage trip Note: Shunt trip and undervoltage trip are described in the Accessories section.
Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers • Magnetic Trip The magnetic (instantaneous) trip element uses an electromagnetic assembly, in series with the load current, to trip the circuit breaker instantaneously (with no intentional delay) at or above a predetermined current value. During a short circuit of significant magnitude, the high level current passing through the conductor rapidly increases the magnetic field of the electromagnet which attracts the armature.
Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers International I/O (ON/OFF) markings appear on the face of each Schneider Electric molded case circuit breaker and molded case switch in addition to the standard ON/OFF markings to indicate handle position. When tripped, the handle assumes a center position. To reset the breaker, the handle is moved to the OFF position and then to the ON position.
Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers • Circuit Breaker Coordination To determine what level of coordination exists between molded case circuit breakers, a comparison of circuit breaker characteristic tripping curves is necessary. A coordination study is an organized effort to achieve optimum electrical distribution system protection by determining the appropriate frame sizes, ampere ratings, and settings of overcurrent protective devices.
Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers Figure 6: Maximum Let-through I2t Energy Let-through I2t curves show the extent to which the current limiting circuit breaker limits energy let-through under short circuit conditions. The theoretical I2t let-through of symmetrical sinusoidal current can be calculated. At 100,000 A rms, this would be 83 x 106 A2 seconds for ½ cycle if NO CURRENT LIMITING DEVICE WERE IN THE CIRCUIT.
Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers • Tripping System Schneider Electric thermal-magnetic molded case circuit breakers have a permanent trip unit that contains a factory preset thermal trip element and a magnetic trip element in each pole. The thermal trip element is rms sensing. In circuit breakers with frame sizes greater than 100 A, the magnetic trip element is field adjustable. A single adjustment simultaneously adjusts the instantaneous trip point in each pole.

Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers — Dielectric Withstand The circuit breaker is subjected to twice its rated voltage, but not less than 900 Vac. When the sample circuit breaker passes these tests, circuit breakers of the same construction can be marked or labeled with the higher current interrupting rating. • Switching Duty The switching duty (SWD) listing applies only to 15 A and 20 A circuit breakers rated at 277 Vac or less.
Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers A circuit breaker with a slash rating, such as 120/240 V or 480Y/277 V, shall be permitted to be applied in a solidly grounded circuit where the nominal voltage of any conductor to ground does not exceed the lower of the two values of the circuit breaker’s voltage rating and the nominal voltage between any two conductors does not exceed the higher value of the circuit breaker’s voltage rating.

Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers The ampere interrupting rating (AIR) of a circuit breaker is the highest current at rated voltage that the circuit breaker is intended to interrupt under standard test conditions. The interrupting rating is shown on the faceplate of the circuit breaker for each voltage level that the circuit breaker can use.
Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers The following procedure is used to determine the continuous current carrying capacity of a thermalmagnetic circuit breaker at ambient temperature other than 104 °F (40 °C) (see data bulletin Determining Current Carrying Capacity in Special Applications for more information): 1. Refer to the ambient rerating curves for the circuit breaker type. 2. Select the curve for the specific amperage rating of the circuit breaker involved.
Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers (Unless the circuit breaker is rated for operation at 100% of its rating). Therefore, the current carrying capacity of a 200 A kA circuit breaker operating under continuous load at 400 Hz would be 200 x 0.92 x 0.80 = 147 A. Figure 9: 400 Hz Thermal Rerating Multiplier At frequencies above 60 Hz, the interrupting capacity of thermal-magnetic circuit breakers is less than the 60 Hz interrupting capacity.
Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers UL Listed 500 Vdc Rated Circuit Breakers Schneider Electric has UL listed dc thermal-magnetic circuit breakers specifically designed for use on ungrounded dc systems having a maximum short circuit (loaded) voltage of 500 Vdc or a maximum floating (unloaded) voltage of 600 Vdc. This UL listed dc rating is available on FH. KH, LH, MH and PA molded case circuit breakers.

Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers Undervoltage Trip The undervoltage trip accessory reduces the possibility of damage to the electrical equipment when a reduction or loss of system voltage occurs.
Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers Undervoltage Trip Time-delay Unit The undervoltage trip time-delay unit, when connected in series with a 120 Vac undervoltage trip, introduces an adjustable time delay of 0.1 to 0.6 seconds in the release of the undervoltage trip coil. This prevents momentary voltage fluctuations from releasing the undervoltage trip coil and nuisance tripping the circuit breaker.
Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers Auxiliary Switch The auxiliary switch accessory monitors the circuit breaker’s contact status and provides a remote signal indicating whether the contact is open or closed. When the circuit breaker is in the OFF or tripped state, the auxiliary switch’s A contact is open and the B contact is closed. When the circuit breaker is ON, the B contact is open and the A contact is closed.
Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers Alarm Switch The alarm switch accessory monitors the circuit breaker’s trip status and is used to provide a remote warning signal indicating the circuit breaker has tripped. This signal can be used in conjunction with a horn, pilot light or some other indicator. The contact on the standard alarm switch is open when the circuit breaker is in the OFF or ON position and is closed when the circuit breaker is in the tripped position.
Legacy Thermal-Magnetic / Magnetic Only Molded Case Circuit Breakers Micrologic Ground Fault Module The Micrologic Ground Fault Module (GFM) is a UL listed self-powered ground fault sensing device that signals a circuit breaker ground fault shunt trip.
