3120-N521-P7T1-W19LG4-3A Description

Short technical summary and product information.

The E-T-A 3120-N521-P7T1-W19LG4-3A is a 2-pole thermal circuit breaker designed for overcurrent protection. It is rated for 3A continuous current and 415V AC operation, with additional availability for 240V AC and 50V DC as noted in the datasheet. The breaker features a rocker actuator and is panel mounted, making it suitable for front-panel applications. A green illuminated indicator with a nominal voltage of 230V provides visual status. The thermal mechanism ensures reliable trip performance under overload conditions. This component is commonly used in industrial control panels, power distribution, and equipment requiring resettable circuit protection.
