The E-T-A 3120-F321-P7T1-W02D-20A is a thermal circuit breaker that combines ON/OFF switching with integral overcurrent protection, conforming to S-type TO CBE to EN/IEC 60934 standards. It features a bimetal trip element and is suitable for overload protection of motors, pumps, transformers, and cables.
This model has a current rating of 20A and a voltage rating of 250VAC or 50VDC. It is designed for panel mounting and features a rocker actuator. The circuit breaker is a 2-pole unit and offers reliable switching behavior due to its positively trip-free mechanism. International approvals include CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.
Additional features and options available for the 3120 series include illumination, water splash protection, auxiliary contacts, under-voltage trip, remote trip, magnetic trip, push-in terminals, and an appliance inlet module. The operating temperature range is -30 to 60 °C. The interrupting capacity is 150A or 250A for 1-pole and 2-pole respectively, with a UL 1077 rating of 5000A or 1000A for AC and DC respectively.
