The E-T-A 3120-N321-P7T1-W16KT4-3A is a thermal circuit breaker that combines overcurrent protection with an ON/OFF switch function. This 2-pole device utilizes a thermal-bimetal trip element and is rated for 3A at 415V.
Designed for overload protection of motors, pumps, transformers, and cables, this circuit breaker can be easily and quickly reset after tripping. Its positively trip-free mechanism ensures reliable disconnection even when the actuator is blocked.
Key features include a panel mount design with a rocker actuator. The device is suitable for various applications including medical and laboratory equipment, apparatus and machine construction, professional tools, and household appliances. It is approved by CSA, GB, IEC, and UL standards.
Additional specifications from the datasheet indicate a rated voltage of 240V AC and 50V DC, with a current rating range of 0.1-20A. Typical life cycles are rated at 30,000 for single-pole and 50,000 for double-pole configurations under specific load conditions.
