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 protec- tion on both poles. Designed for snap-in panel mounting with illumina- tion 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. q Under voltage release coil (for double pole versions only). q Magnetic trip coil for short circuit protection. q Magnetic trip coil for remote relay trip. q Auxiliary contacts for status signalling. q Mechanical slide interlock. Approved to CBE standard EN

60934 (IEC 60934). Available accessories: water splash protection and actuator guard to prevent inadvertent operation. Technical data 3120-F7.. Approvals Current Internal rating resistance per (A) pole (?) 0.1
