JCMX Shunt trip release MX

JCMX Shunt trip device is a trip device excited by a voltage source, and its voltage may be independent of the voltage of the main circuit. Shunt trip is a remotely operated switching accessories.


When the power supply voltage is equal to any voltage between 70% and 110% of the rated control power supply voltage, the circuit breaker can be reliably broken. Shunt trip is a short-time working system, coil power time generally can not exceed 1S, otherwise the line will be burned. In order to prevent coil burn, a micro switch is connected in series in the shunt trip coil. When the shunt trip is closed through the armature, the micro switch changes from normally closed state to normally open. Because the control line of the power supply of the shunt trip is cut off, the shunt coil is no longer energized even if the button is held artificially, so the burning of the coil is avoided. When the circuit breaker is closed again, the micro switch is returned to the normally closed position.
JCMX Shunt Trip Release is designed to offer only shunt trip release function without any auxiliary feedback, allowing for a more streamlined and efficient operation.
The JCMX shunt trip release is responsible to trip the circuit breaker when a voltage pulse or an uninterrupted voltage is applied to the device coil. When the shunt release is live, contact with the switch's main contacts on switching on is reliably prevented.
JCMX shunt trip device is an optional accessory in a circuit breaker that mechanically trips the breaker when power is applied to the shunt trip terminals. The power for the shunt trip does not come from within the breaker, so it must be supplied from an external source.
JCMX shunt trip breaker is a combination of the shunt trip accessory and the main circuit breaker. This installs on the main breaker to add protection to your electrical system. This adds security to your electrical system as it manually or automatically cuts the electric supply in your circuit. This accessory can help prevent short circuits and avoid electrical damage should a disaster occur in your home.
JCMX shunt trip is an optional accessory for a circuit breaker for added protection to your system. It is designed to connect to a secondary sensor. It will trip the breaker automatically if the sensor is triggered. It can also be activated via a remote switch that you can install.
