Discover the Accessories Available for the 3120-N


The 3120 circuit breaker switch combination is a time and cost savings solution for equipment and machines. It's even easier and safer to operate and offers significantly improved water and dust protection. Well-proven a million times over, the 3120 serves as an on/off switch and also reliably disconnects overcurrent. After tripping, the user can immediately reset the 3120 and resume operation.

The 3120 version with push in connection technology is globally unique. Thanks to consistently high spring forces at the terminal it ensures a permanently stable cable connection. The easy connect plug in connector reduces wiring time during assembly. It can be plugged on quickly without any tools.

An optional undervoltage release module prevents automatic restart after a power failure. This eliminates the possibility of injuring operating personnel. Including the 3120 in a power entry module greatly reduces the number of individual components for equipment manufacturers. E-T-A's 3120 circuit breaker switch combination makes your product more reliable and cost effective all while keeping safety a priority.
