Switchboard of ЩРПА, BSM (B) type

 

Description

ЩРПА, BSM(В) is an electrical cabinet. Switchboards are designed for the assembly of power switchboards with modular equipment for input and distribution of electric energy, as well as for the protection of networks with voltage of 380/220V against overload and short circuit.

Switchboard SB is a metal structure, divided by a partition into three compartments: accounting, distribution and low current compartments. Counters, circuit breakers and power down protection devices are respectively installed in each compartment.



Certificates

Boards are produced in accordance with the technical conditions TU 3430-007-61938140-2014, and fully meet the requirements of technical regulations of the Customs Union TR CU 004/2011 and TR CU 020/2011.



Functions

- Reception and distribution of electric energy of 380/220 V, 50 Hz;

- Protection against electric shock in case of accidental contact with live parts;

- Prevention of fires caused by the ignition of wire insulation due to excessively high earth leakage;

- Protection against rare opening and closing of branch circuits lines, as well as for protection in case of overloads and short circuits.



Application area

It is used in industrial and welfare facilities, in small power centers such as supply to floor, workshop, home, office centers.
