Air Circuit Breakers
Air circuit-breakers can be used both as circuit-breakers for general protection (of plants, of user complexes, of electric lines) and as protection circuit-breakers of electrical machines (generators, motors, transformers, capacitors).
Miniature Circuit Breakers
MCBs protect installations against overload and short-circuit, warranting reliability and safety for operations.
Manual Motor Starters
MMS are used mainly to switch motors manually ON/OFF and protect them and the installation fuse less against short-circuit, overload and phase failures. Fuse less protection with a manual motor starter saves costs, space and ensures a quick reaction under short-circuit condition, by switching off the motor within milliseconds.
Moulded Case Circuit Breakers
Tmax moulded-case circuit-breakers guarantee an extremely high performance level while being progressively smaller in size, simple to install and able to provide increasingly better safety guarantees for the operator.
