This accessory provides remote indication when a circuit breaker or supplementary protector is tripped.

Features IP20 guarded terminals to protect against accidental contact with live parts and snaps-on and installs without the use of tools.
Side Mounted Shunt-Trip Modules
Shunt-trip modules enable the circuit breaker or supplementary protector to trip, there by cutting off the power supply to any machine or equipment remotely. These modules snap onto the right side of the circuit breaker or supplementary protector without the use of tools.
