SCHNEIDER MX-XF/SHT-SHC Voltage Coils
Product manual:
Schneider MX-XF/SHT-SHC voltage coil is an accessory component designed specifically for industrial circuit breakers or switchgear, typically used for remote control and circuit breaker protection operations. The following is detailed information about the voltage coil:
major function
MX-XF (shunt trip coil):
Used for remote disconnection of circuit breakers.
When receiving a voltage signal, trigger the circuit breaker to trip and cut off the power supply.
Usually used for emergency shutdown or protective tripping.
SHT-SHC (undervoltage trip coil):
Used to monitor the voltage status of the power supply.
If the voltage is lower than the set value (under voltage condition), the circuit breaker will automatically trip.
Used to prevent equipment from operating under unstable voltage conditions and ensure safety.
