Porduct Overview

Description

Auxiliary contact: linked with ON, OFF mechanism of main circuit of circuit breaker, mainly used for indication of circuit breaker ON, OFF status. To connect it into control circuit of breaker, through ON and OFF of circuit breaker, the auxiliary contact can take control or interlock to related electrical device.

The Alarm Auxiliary accessory indicates when a Miniature Circuit Breaker or Supplementary Protector is tripped. A trip can be a result of an overload, short-circuit, operation of Shunt-trip accessory, or Undervoltage / Overvoltage module.
