JCMX Shunt Trip Release: A Remote Power Cut-Off Solution for Circuit Breakers
The JCMX shunt trip release is a device that can be attached to a circuit breaker as one of the circuit breaker accessories. It allows the breaker to be turned off remotely by applying electrical voltage to the shunt trip coil. When voltage gets sent to the shunt trip release, it activates a mechanism inside that forces the breaker contacts to trip open, shutting off the flow of electricity in the circuit. This provides a way to quickly shut off power from a distance if there is an emergency situation detected by sensors or a manual switch. The JCMX model is designed just for this remote tripping function without any extra feedback signals as part of the circuit breaker accessories. It connects directly onto compatible circuit breakers using a special pin mount.
Notable Features of the Jcmx Shunt Trip Release
The JCMX Shunt Trip Release has several notable features that allow it to reliably trip a circuit breaker from a remote location. One key feature is:
Remote Tripping Capability
The main feature of the JCMX Shunt Trip Release is that it allows a circuit breaker to be tripped from a remote location. Instead of having to manually operate the breaker, voltage can be applied to the shunt trip terminals which then forces the breaker contacts to separate and stop the flow of electricity. This remote tripping can be initiated by things like sensors, switches, or control relays wired to the shunt trip coil terminals. It provides a way to quickly cut power in an emergency without accessing the breaker itself.
Voltage Tolerance
The shunt trip device is designed to work reliably across a range of different control voltages. It can operate properly on any voltage between 70% to 110% of the rated coil voltage. This tolerance helps ensure dependable tripping even if the voltage source fluctuates or drops somewhat due to long wiring runs. The same model can be used with different voltage sources within that window. This flexibility allows consistent operation without being affected by minor voltage variations.
No Auxiliary Contacts
One simple but important aspect of the JCMX is that it does not include any auxiliary contacts or switches. Some shunt trip devices have built-in auxiliary contacts that can provide a feedback signal indicating if the shunt trip has operated. However, the JCMX is designed solely for the shunt trip release function itself, with no auxiliary components. This makes the device relatively basic and economical while still providing the core remote tripping capability when needed.
Dedicated Shunt Trip Function
Since the JCMX has no auxiliary contacts, it is dedicated entirely to just performing the shunt trip release function. All of the internal components and mechanisms are focused solely on this one task of forcing the breaker to trip when voltage is applied to the coil terminals. The shunt trip components are optimized specifically for rapid and reliable tripping action without having to integrate any other features that could potentially interfere with the shunt trip operation.
Direct Breaker Mounting
The final key feature is the way the JCMX Shunt trip release MX directly mounts onto compatible circuit breakers using a special pin connection system. On breakers made to work with this shunt trip, there are mounting points on the breaker housing itself precisely lined up with connections for the shunt trip mechanism. The shunt trip device can plug directly into these mounting points and link its internal lever to the breaker's trip mechanism. This direct mounting allows a very secure mechanical coupling and robust tripping force when needed.
The JCMX Shunt Trip Release is one of the circuit breaker accessories that allows a circuit breaker to be tripped remotely by applying voltage to its coil terminals. Its key features include the ability to reliably trip the breaker from a distance, tolerance to operate across a range of control voltages, a simple dedicated design with no auxiliary contacts, internal components optimized solely for the shunt trip function, and a secure direct mounting system to the breaker's trip mechanism. With this dedicated shunt trip accessory as part of the circuit breaker accessories, circuit breakers can be safely forced to open when needed by sensors, switches or control systems without locally accessing the breaker itself. The robust shunt trip mechanism, free of other integrated functions, helps provide reliable remote tripping capability for enhanced protection of equipment and personnel.
