3120-N321-H7T1-W04L-10A Description

Short technical summary and product information.

The E-T-A 3120-N321-H7T1-W04L-10A is a thermal circuit breaker that combines overcurrent protection with the function of an ON/OFF switch. It utilizes a bimetal trip element for reliable operation.

 

This 2-pole breaker is rated for 10A and operates at up to 240V AC or 50V DC, with an option for 415V AC upon request. It is designed for panel mounting and features a rocker actuator. The breaker is suitable for protecting motors, pumps, transformers, and cables against overloads.

 

Key features include a positively trip-free mechanism for reliable disconnection and quick resettability after tripping. The breaker is designed for applications requiring robust overload protection and maximum equipment availability, with a typical life of 30,000 to 50,000 cycles depending on pole configuration and load type.

 

Typical applications include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools. It is also suitable for use in medical equipment according to IEC/EN 60601.
