3120-N Next-Generation Circuit Breaker/Switch

E-T-A Circuit Breakers 3120-N Next-Generation Circuit Breaker/Switch combination unites overcurrent protection and the function of an ON/OFF switch within a single component. The trip element is a thermal bimetal. 3120-N Next-Generation Circuit Breaker/Switch, which replaces the 3120-F series, is ideally suited for overload protection of motors, pumps, transformers, and cables. After tripping, the device can reliably, easily, and quickly be reset. The positively trip-free mechanism ensures reliable circuit disconnection even with the actuator blocked.
