Effective protection of 3-phase motors against overcurrent's and short circuits while minimizing false tripping is a challenging application. IMO's C4 range of Motor Circuit Breakers are tailor made for this task, featuring a range of features to maximize protection while reducing unnecessary down-time. Based on combined thermal / electro-magnetic technologies, overcurrent protection can be precisely set to the required current draw, while the electromagnetically activated short circuit protection is preset at 13 x the nominal current, avoiding false trips at startup due to current inrush.

Inbuilt phase failure protection provides additional protection from overheating and resultant damage, while an extensive range of accessories includes undervoltage or shunt trip modules, signalling and alarm contacts and installation products such as busbar, combination mounting kits and door-interlock adaptors. All devices may be mounted on 35mm DIN rail, or in the case of C4/100 types, 75mm DIN rail. Operating handles are padlockable for isolation purposes and units may be equipped with other safety features such as covers for the current setting scale and additional insulation barriers for higher voltage applications.
