The induction motors are widely used in numerous fields: processing and extractive industries, construction and communal services, power engineering and transport. The electrical motors are indispensable devices used in fans, pumps, conveyors, processing machine-tools, mixers, handling mechanisms, shutters and gates, compressors, etc.

Bus connection to the automatic circuit breaker allows to reduce the contact resistance and provides a 2- or 3-wire connection of the line for uniform distribution of bus load.

Increased size of the screw head with multiple-purpose slot (+, -) facilitates the assembly and prevents the falling out of screws during installation.

The improved switch handle of wider size with increased contact area facilitates the switching process.

Protection of heat release mechanism by plexiglass against change of factory settings.

Silver-containing composite weld deposition increases the wear resistance of the contact group and reduces the contact resistance.

The switch design provides for two types of protection against overload and short circuit, that significantly improves the protection of distribution and group circuits.

Unified casing with the ability to connect additional devices does not require dismantling, as well as provided with the ability to self-connect.

Notches on the contact clamps reduce heat loss and increase the mechanical stability of the connection.

Special casing design with increased heat transfer allows you to raise the loading capacity by 10%.

The status indicator of the main circuit provides accurate information on the status of contacts regardless of handle position.

Circuit breaker BA47-29M 3P 10A 4.5kA B IEK

Modular circuit breakers (MCB) VA47-60 are intended for automatic power source cut-off under excess currents.
Recommended for use in group panels (apartment and floor) and distribution boards of residential, domestic, public and administrative buildings.

Protection of the mechanism of the thermal release with a plexiglass insert from changing factory settings.

the increased strength of the case in the attachment zone of conductors due to two additional rivets and a monolithic front panel.

the ability to simultaneously join the FORK tire and a flexible conductor to distribute the power supply through the upper clamps, as well as the possibility of connecting the PIN bus.

The attack from the silver -containing composite increases the wear resistance of the contact group and reduces the transition resistance.

improved arcaming system: increased service life, increased resistance to short -circuit currents: patent No. RU 139886.

Additional protection against the burning of the circuit of the circuit breaker and heat removal due to the plastic and metal anti -agricultural plates.

Fast installation and additional reliability of mounting on a DIN-rack using a latch with a double fixed position.

The presence of the contact position indicator.

notes on contact clamps reduce heat losses and increase the mechanical stability of the connection.
