Please contact your local Schaffner partner for individual application support. Typical block schematic Temperature monitoring function All filters of this range are equipped with a temperature monitoring function. The built- in temperature sensor opens a potential-free contact in the case of filter overtemperature (>120 C). The maximum switching capability is 6A/250 V. This function can be used, for example, in the input of a CNC controller or as the trip of a circuit breaker in order to interrupt the mains power supply. Connec- tions are located next to the phase con- nectors (see mechanical data for details). Forced cooling The 75 A and 120 A filters provide internal cooling fans which require external power supply (24 VDC/~4 W). Connections are located next to the connectors of the temperature sensor (see mechanical data for details).
