Modular circuit breakers (MCB) VA47-29 are intended for protecting distribution and group systems having different loads:
– electric appliances, lighting – B characteristic switches;
– drives with moderate starting currents (compressor, fan group) – C characteristic switches;
– drives with high starting currents (hoisting mechanisms, pumps) – D characteristic switches;
Modular circuit breakers VA47-29 are recommended for use in electrical distribution panels of residential and public buildings.

Bridging contact provides high electrical insulation properties.

Connection terminals allow you to connect the conductors of a cross section from 1 to 25 mm2.

Contacts are made of silver-containing material, it increases their durability, prolongs the service life and reduces the contact resistance and loss.

Increased reliability due to the use of stranded conductor for connection of the coil winding.

Auxiliary contact interchanges control coil windings, decreasing the holding current by 5 times compared with the start current.

Compatibility of sizes allows you to install the contactor in a standard board with any devices of modular series.

Visual indication of the status of main contacts and main technical parameters.

In the control coil circuit a rectifier bridge is mounted that allows to control the 220 VDC coil.
