E-T-A Circuit Breakers, quality designer and manufacturer of a broad range of electro-mechanical and electronic products for circuit protection, has introduced a new variant of its extremely versatile and reliable 3120 Series of rocker-actuated, combined switch / circuit breakers. The optional integral LED illumination in a range of colours that is now available on the Type 3120 offers power saving and improved endurance compared to earlier versions with filament bulbs. The well-proven 3120 is used widely for applications which include electrical machinery, power tools, household appliances and garden machinery, as well as for marine control panels, medical equipment and communications systems.

3120 with LED

The versatile S-type E-T-A 3120 thermal circuit breaker range is designed for frequent ON/OFF switching under normal load conditions, at the same time providing accurate overcurrent protection with a trip-free mechanism. The illumination is offered in a choice of red, yellow, green and blue. The 3120 is suitable for switching applications up to 50V DC or 240/415V AC with a choice of current ratings from 0.1A up to 20A for single or double-pole applications. Designed for snap-in frame mounting, it can be specified with a water splash protection cover for rugged environments, and an actuator guard that protects against inadvertent resets.

The new LED versions require less than 2mA in operation, compared to earlier versions with filament bulbs which required between 20mA and 60mA. Improved illumination endurance, as well as reduced susceptibility to shock, vibration and low temperatures, also means lower maintenance requirements.

The E-T-A 3120 range carries EN 60934 Circuit Breaker for Equipment approval as well as approvals from respected authorities such as UL and CSA. The 3120 provides proven reliability for many demanding applications, including recreational and workboats as it is suitable for even the harshest conditions experienced at sea.
