This E-T-A 3120-N series thermal circuit breaker combines overcurrent protection with an ON/OFF switch function. It is designed for overload protection of motors, pumps, transformers, and cables, offering reliable tripping and easy resetting. The positively trip-free mechanism ensures disconnection even with a blocked actuator.
Key electrical specifications include a 15A current rating and a 415V AC voltage rating, with a DC voltage rating of 50V. This 2-pole breaker features a thermal trip element and a rocker actuator for panel mounting. It is suitable for various applications including medical and laboratory equipment, apparatus and machine construction, and household appliances.
The breaker is designed for efficient mounting and wiring, with optional push-in terminals available for quick installation. Its compact design contributes to space saving and reduced storage costs, increasing overall equipment reliability. The internal resistance per pole is typically 0.0325Ω at 5A.
Typical life expectancy for this 2-pole unit is rated at 50,000 cycles at 1 x IN under inductive load conditions at 240V AC. It also meets approval standards such as UL1077 and IEC 60934.
