The 3120 circuit breaker/switch combination is a time- and cost-saving solution for equipment and machines.  It is 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 re-start 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.
