Providing motor short-circuit protection on the category of AC3 IEC60947. Protection and control of Single-phase or 3-phase motors.

Isolation and breaking Function.

Short-Circuit protection.

Power Switching.

Non-Reversing.

MPCB are designe for connecion by screw clamp terminals. It can be supplied with lugs or spring terminal connections. Resistant to harsh environment, vibration and impact and are even more effective when conductors without cable ends are used. Each connection can take two independent conductors.

Operation:

Control is manual and local when the motor circuit-breaker is used on its own. Control is automatic and remote when it is associated with a contactor.

Pushbutton control:

Energisation is controlled manually by operating the Start button "I".

De-energisation is controlled manually by operating the Stop button "O", or automatically by the thermal-magnetic protection elements or by a voltage trip attachment.

The motor circuit-breakers are easily installed in any configuration thanks to their universal fixing arrangement: screw fixing or clip-on mounting on symmetrical, asymmetrical or combination rails.
