Accessory Connections
Electrical accessories are fitted with numbered terminal blocks for wires with the following maximum size:
• 16 AWG (1.5 mm
2
) for auxiliary switches (OF1 or OF2), and shunt trip (MX) or undervoltage trip (MN)
• 14 AWG (2.5 mm
2
) for the motor operator
Auxiliary switch wiring exits fixed mounted devices through a knock-out in the front cover.
NOTE: See page 140 for plug-in and page 142 for drawout options.
Auxiliary and Alarm Indication Contacts
Auxiliary indication contacts provide remote information of the circuit breaker status and can thus be
used for indications, electrical locking, relays, etc.
Auxiliary Switch (OF)/
Alarm Switch (SD)
Overcurrent Trip
Switch Actuator (SDE)
Table 88: Auxiliary and Alarm Indication Contacts
Applications
Open/Closed—Auxiliary Switches (OF)
• Indicates the position of the circuit breaker contacts
Trip Indication—Alarm Switch (SD)
• Indicates that the circuit breaker has tripped due to an overload, short circuit or ground fault, the operation of
a shunt trip or undervoltage trip or the “push-to-trip” button
• Resets when the circuit breaker is reset
Overcurrent Trip Switch (SDE)
• Indicates that the circuit breaker has tripped due to an overload, short circuit or ground fault
• Resets when the circuit breaker is reset
The above switches are also available in low-level versions (with gold flash plating) capable of switching very
low loads (e.g., for controlling PLCs or electronic circuits)
Rotary Handle Indicator: CAO (early-break) and CAF (early-make)
• Fitted in the rotary handle module (see page 127)
Installation &
Connection
• The auxiliary switch (OF), alarm switch (SD), and overcurrent trip switch (SDE) indication contacts snap into
cavities behind the front accessory cover of the circuit breaker.
• One model serves for all indication functions depending on where it is fitted in the circuit breaker.
• The overcurrent trip switch (SDE) in a circuit breaker equipped with a thermal-magnetic or Micrologic 1/2/3
trip unit requires the SDE actuator.
Standards
• The internal accessories comply with requirements of Underwriters Laboratories
®
Inc. (UL
®
).
• UL 489 and Canadian Standard Association C22.2 No. 5-02 Standards.
• All internal accessories are Listed for field installation per UL file E103955 and Certified under CSA file LR 69561.
• Auxiliary indicator contacts comply with UL 489, CSA C22.2 No. 5-02 and IEC 60947-5 Standards. “Low-
level” indicator contacts are not UL Recognized.

If the maximum voltage and current is exceeded, the low-level function of the switch will be lost but the switch will
continue to function as a standard switch.
