E-T-A Circuit Breakers XR38 Appliance Inlet Modules are designed for circuit breakers with a 3/8″ threadneck (106/1140/1658/2-5700/8330 circuit breakers). The E-T-A XR38 modules combine up to three functions in one component: a C14 inlet plug, resettable overcurrent protection, and a line filter. Users can select appropriate line filters for the use of the appliance inlet module in medical equipment applications according to IEC/EN60601-1. The series offers two standard versions: version C without an actuator guard (reset button protrudes from the module) and version D with an actuator guard (reset button completely recessed). These modules feature screw-type mounting from the front or rear.
