This E-T-A 3120-N series thermal circuit breaker, part number 3120-N551-P7T1-W01D-X3120-M2P7M-230V-16A, combines overcurrent protection with an ON/OFF switch function. It is rated for 16A and operates at up to 240V AC or 50V DC, with an option for 415V AC.
The breaker utilizes a thermal-bimetal trip element and is suitable for protecting motors, pumps, transformers, and cables from overloads. It offers a positively trip-free mechanism for reliable disconnection, even with a blocked actuator. The device is designed for easy and quick reset after tripping.
Featuring a panel mount design and a rocker actuator, this 2-pole circuit breaker is approved by CSA, GB, IEC, and UL standards. Its typical life is rated for 30,000 cycles at 1x IN for single-pole operation and 50,000 cycles for double-pole operation under specific conditions.
Typical applications include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools. The component is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) of 1.
