This E-T-A 3120-N321-P7T1-W02D-18A is a thermal circuit breaker designed for overcurrent protection. It combines the function of a circuit breaker with an ON/OFF switch in a single component, utilizing a thermal-bimetal trip element.
Key electrical specifications include a voltage rating of 415V and a current rating of 18A. This model is a double-pole unit, offering enhanced protection capabilities. The internal resistance per pole is less than 0.02Ω.
The circuit breaker is designed for panel mounting and features a rocker actuator for operation. It is suitable for various applications requiring reliable overload protection for motors, pumps, transformers, and cables. The positively trip-free mechanism ensures reliable disconnection even when the actuator is blocked.
Compliance is noted with agencies such as CSA, GB, IEC, and UL. The device is specified as RoHS3 Compliant, MSL 1 Unlimited, and REACH Unaffected, though these statuses are marked with low confidence due to lack of verification.
