Schaltbau fusible overtemperature protection and tripping devices ensure fail-safe thermal cut-out protection against overheating of electric air heaters used in rail vehicles and stationary heating systems. These devices are a prerequisite for fire protection and operate completely independently of the heater control device.,the device must be connected into the heater load circuit. Each device of the various series must have a fuse installed prior to installation. Fusible links are available in a variety of trip temperatures,so you can order a fuse that exactly matches your application's requirements. This is why fuses are not included when providing any overheating protection or tripping devices.,insufficient air flow or a faulty heater control can cause the system to quickly overheat. When the fuse's fixed temperature setpoint is exceeded,the device shorts the heater load circuit,tripping the series fuse. This will prevent current from flowing through the component and provide protection from the heater returning to operation after over-temperature conditions
