The E-T-A 3120-N321-P7T1-W14FR4-10A is a thermal circuit breaker and switch combination that provides reliable overcurrent protection. It is a double-pole device with a 10A current rating and is suitable for AC voltages up to 240V and DC voltages up to 50V. The breaker features a rocker actuator and is designed for panel mounting.
This thermal circuit breaker utilizes a bimetal trip element for overload protection, making it ideal for safeguarding motors, pumps, transformers, and cables. It offers a positively trip-free mechanism for reliable disconnection, even with a blocked actuator. The unit can be easily and quickly reset after tripping. Its typical applications include medical and laboratory equipment, apparatus and machine construction, professional tools, and household appliances.
Key specifications include a 240V AC and 50V DC voltage rating, a 10A current rating, and a 2-pole configuration. The breaker is approved by CSA, KTL, UL, and VDE. It is designed for durability with a typical life of 30,000 cycles at 1x IN for single-pole operation and 50,000 cycles for double-pole operation under specified conditions.
