Tripping device with auxiliary switch, short
Schaltbau fusible overtemperature protection and tripping devices ensure fail-safe thermal cutout protection against overheating of electric air heaters as used in rail vehicles and stationary heating systems. The devices are a prerequisite for fire protection and operate totally independent of the heater controls.
The device must be wired into the heater load circuit. Prior to installation, every device of the various series must be fitted with a fusible link. Fusible links are available with a number of trip temperatures, so you can order the one fusible link which meets exactly the requirements of your application. That is why fusible links are not included in delivery of any overtemperature protection or tripping device.
Insufficient air flow or failure of heater control results in rapid overheating of the system. When the fixed temperature set point of the fusible link is exceeded, the device shorts the heater load circuit, tripping a series-connected fuse. This stopps the flow of current through the components, and provides protection against any return to operation of the heaters in an overtemperature condition.
