Indicates the position of the circuit breaker contacts
Bell alarm 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
Indicates that the circuit breaker has tripped due to an overload, short circuit or ground fault
Resets when the circuit breaker is reset
The OF, SD and SDE switches 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 SDE function of a circuit breaker equipped with a thermal-magnetic trip unit requires the SDE adapter
The internal accessories comply with requirements of Underwriters Laboratories
UL 489 and Canadian Standard Association C22.2 No. 5-02 Standards
All internal accessories are Listed for fixed installation per UL file E103955 and Certified under CSA file LR 69561
Auxiliary switches comply with UL 489, CSA C22.2 No. 5-02 and IEC 60947-5 Standards
