The E-T-A 3120-N series thermal circuit breaker combines overcurrent protection with the function of an ON/OFF switch. It utilizes a thermal-bimetal trip element and is suitable for protecting motors, pumps, transformers, and cables from overload conditions. The positively trip-free mechanism ensures reliable disconnection even when the actuator is blocked.
This specific model, 3120-N321-P7M1-W01A-2.5A, is rated for 2.5A and operates at up to 415V AC or 50V DC. It features a panel mount design with a rocker actuator and has two poles for circuit interruption. The breaker is approved by CSA, GB, IEC, and UL standards.
Key features include a current rating range from 0.1 to 20A and voltage ratings of AC 240V and DC 50V, with AC 415V available upon request. The device is designed for easy and quick resetting after tripping, ensuring maximum equipment availability. Its compact design also contributes to reduced mounting and wiring time.
Typical applications for the 3120-N series include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, and audio equipment.
