This E-T-A 3120-F321-P7T1-W19LG4-15A is a thermal circuit breaker designed for overload protection of motors, pumps, transformers, and cables. It functions as an ON/OFF switch with integral overcurrent protection, utilizing a bimetal trip element.
The circuit breaker has a current rating of 15A and a voltage rating of 250VAC or 50VDC. It features a rocker actuator for operation and is designed for panel mounting. The device is a 2-pole unit.
Key technical specifications include a rated voltage of 240VAC/50VDC and a current rating range of 0.1 to 20A. Typical life expectancy is 30,000 operations for single-pole configurations and 50,000 operations for double-pole configurations under specific conditions. The operating ambient temperature range is -30 to 60 °C.
Additional features include green illumination with a nominal voltage of 185V. The circuit breaker is approved by CSA, GB, IEC, and UL standards. It offers an interrupting capacity of 150A (1-pole) and 250A (2-pole) at its rated voltage, with UL 1077 ratings of 5000A at 250VAC and 1000A at 50VDC. The operating area has a degree of protection of IP40, which can be increased to IP54 or IP66 at the terminal area with a water splash cover.
