Internal connection diagrams

E-T-As proven type 3120 in a new attractive styling (S-type TO CBE to

EN 60934 with trip free mechanism) offering the choice of single pole,

double pole with single pole protection, and double pole with protection

on both poles. Designed for snap-in panel mounting with illumination as

an option. Under overload conditions the rocker returns to the OFF

position.

Any one of the following additional function modules can be supplied

factory fitted to the rear of the switch/circuit breaker.

- Undervoltage release coil (for double pole versions only).

- Magnetic trip coil for short circuit protection.

- Magnetic trip coil for remote relay trip.

- Auxiliary contacts for status signalling.

- Mechanical slide interlock.

Approved to CBE standard EN 60934 (IEC 60934).

Available accessories: water splash protection and actuator guard to

prevent inadvertent operation.
