E-T-A Circuit Breakers Ltd

An E-T-A classic with a new look

E-T-A’s 3120 circuit breaker works as an ON/OFF switch in machinery and devices. It also provides reliable disconnection in the event of an overcurrent. After tripping due to an overcurrent, the user can easily and quickly reset the 3120-N to resume operation. Time-consuming replacement of fuses is eliminated. Now, the well-proven classic presents itself with a new accordion-style seal.

Enhanced uptime of equipment and machinery

The new innovative bellows-type seal offers IP65 degree of protection. Even fine dust or water jets will not cause any damage. Failures or machine downtimes are prevented.

Compared to standard PVC splash covers, the new E-T-A accordion-style seal not only protects the actuation area, but it also protects the mounting hole with an all-round rubber lip.

With regard to environmental influences, the new accordion-style seal has quite a few advantages. Conventional splash covers made of PVC become yellow when exposed to the sun. They also become brittle and can crack due to environmental influences. The silicone seal, however, is unsusceptible to ozone and ultraviolet light. Acids or oils cannot damage the new seal either. This is very positive, because discoloured or dirty splash covers often block the visibility of the rocker and its position.

Easy actuation

The new seal of E-T-A’s 3120-N series leaves the rocker actuator easily accessible. Switching the device is simple, even when the user is wearing gloves. And what is more: Due to the freely accessible rocker actuator, the switching condition (ON or OFF) can always clearly be discerned.
