Trip mechanism
WebApr 1, 2024 · The 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. Webwith a shunt trip mechanism. The shunt trip is operated by a control relay (called a fire safety interface relay) in the unit that is wired to a normally open contact in the remote fire alarm control panel (FACP). When the FACP receives a signal from the fire alarm system that there is going to be a sprinkler release in an elevator shaft,

WebThus, the spring mechanism exerts an essentially constant force on the trip plate and turning the setpoint adjustment screw changes the direction of this force. Turning the setpoint screw clockwise (CW) aligns the spring force more fully in the untripped direction (below the pivot – see Figure 1), making it more difficult to trip the device.
