Three light-emitting diodes indicate separately longtime, short-time/ instantaneous and ground-fault trip. A flat push button allows resetting of the indicator after tripping.
Control Units Overcurrent Trip Switch (SDE) 06313029 Delivered standard with control unit. In addition to the fault trip indicator/reset button, one SPDT switch provides alarm/lockout information. This SPDT switch is operated only when the circuit breaker is tripped by the control unit. When the circuit breaker is reset, the "a" switch (alarm) is open and the "b" switch (lockout) is closed.
06313033 Control Units Load monitoring (R) push to reset Option R provides two independent static contacts which operate when the current exceeds adjustable pickup limits: n When the current exceeds the limit Ic1 (or Ic2), the contact C-R1 (or C-R2) closes following an inverse time characteristic A. n When the current drops below the limit Ic1 (or Ic2), the contact C-R1 (or C-R2) opens with constant time delay (10 seconds) B. These contacts can be used for load shedding, alarms, indications, etc.
Control Units Communication MASTERPACT circuit breakers can be easily connected to a supervising personal computer using the DIGIPACT® system.

Accessories The MASTERPACT circuit breaker is equipped with a true two-step stored energy mechanism which ensures fast opening and closing operations and complete open-close-open sequence without recharging the mechanism. The MASTERPACT circuit breaker has manual actuators that include a charging handle and push-to-open and push-to-close buttons.
06313049 Accessories Closing Coil (XF) 06313050 This device releases the circuit breaker closing mechanism when the spring is charged. The closing coil is rated for continuous duty. The closing release is supplied on request and can be fitted even on a manual operating mechanism. Remote Close A4 XF A1 Anti-pumping Function When the closing coil (XF) is permanently energized, the circuit breaker remains in the open position after it has been opened, either by manual or electrical operation.
Accessories Opening Coils Three types of voltage releases can be used for remote opening of the circuit breakers: n Shunt trip (MX) n Instantaneous undervoltage trip device (MN) n Time-delayed undervoltage trip device (MNR) Possible Combinations 06313049 Each MASTERPACT circuit breaker can be equipped with: n One shunt trip (MX) + one undervoltage trip device (MN or MNR) n Or two shunt trips (MX) Shunt Trip (MX) This release is rated for continuous duty and operates with control voltages between 85% and
Accessories Time-delayed Undervoltage Trip Device (MNR) (1) To prevent the circuit breaker from tripping in the event of transient voltage drops, this release has a built-in adjustable time delay. If required, this time delay can be overridden by connecting an external switch on an additional circuit (wired by the user). The undervoltage trip device is fieldinstallable.
06313055 Accessories 24 Additional Auxiliary Switches (OFSUP) An external plate holds a set of 24 SPDT switches operated by means of a cable. They are available only for drawout circuit breakers. Standard Auxiliary Switches (O and F) 06313056 2a + 2b switches available as standard: n "a" contacts are open when the circuit breaker is open and closed when the circuit breaker is closed. n "b" switches are closed when the circuit breaker is open and open when the circuit breaker is closed.
Accessories Connected Position Switches (CE) A block of four SPDT switches operate when a drawout circuit breaker is in the connected position. The switch block is field-installable. Disconnected Position Switches (CD) A block of two SPDT switches operate when a drawout circuit breaker is in the disconnected position. The switch block is field-installable. See page 30 for operating diagrams.

Accessories Push Button Locking Device (VBP) This device prevents local manual operation of the circuit breaker by covering the opening and/or closing the push buttons. This locking device can be locked by a padlock or a sealing lead. Open Position Lock (VSKA) 06313063 06313064 A key interlock that locks the circuit breaker in the open position by holding the push button in its depressed position. The key interlock is provided.
Accessories Mechanical Interlocks n Disconnecting When Circuit Breaker Is Closed: During any disconnecting attempt when the circuit breaker is closed, an interlocking device ensures the tripping of the circuit breaker before the actual separation of the main disconnects. The circuit breaker remains, however, operable in the other positions: test, disconnected and withdrawn.
Accessories 06313067 Interlocking Rods and Cables Two or three MASTERPACT circuit breakers can be mechanically interlocked by means of rods or cables. This accessory is mountable on the right side of the circuit breaker. This adaptation can be made on site without modifying the circuit breaker.
Accessories Safety Shutters (VO) Comprising two independent parts, line and load side, the safety shutters automatically block access to the main disconnects when the circuit breaker is in the disconnected, test or fully withdrawn position.
Accessories Interphase Barrier (EIP) Mounted between terminals of the stationary assembly, the interphase barrier prevents arc prolongation to the circuit breaker in the event of a line side fault and isolates the circuit breaker connections in insulated bus bar installations. Transparent Cover (CB) 06313076 06313075 Hinged-mounted and locked with a milled head, this cover is designed to be installed on the door escutcheon.

Appendix Routine Maintenance Guidelines DANGER HAZARD OF ELECTRICAL SHOCK, BURN OR EXPLOSION. Turn OFF all power supplying the equipment before installing or removing circuit breaker. Failure to observe these precautions will cause death, personal injury or electrical shock. CAUTION HAZARD OF EQUIPMENT DAMAGE. Since circuit breakers contain factory-sealed and calibrated elements. Do not break seal.
Appendix Insulation Resistance Tests When circuit breakers are subjected to severe operating conditions, an insulation resistance test may be performed as indicated in NEMA standard publication No. AB4-1991. An insulation resistance test is used to determine the quality of the insulation between phases and phase-toground. The resistance test is made at a dc voltage higher than the rated voltage to determine the actual resistance of the insulation. The most common method employs a "megger" type instrument.
