Hanging light board of LB, ОЩВ, УОЩВ type

 

Description

Boards protect electric lighting circuits with voltage up to 380V against short circuits, overloads. It is also possible to install leakage-current protection devices, relay protection against excessive power consumption, as well as devices, actuating in case fire or smoke generation in powered lighting equipment.



Certificates

LB complies with TR CU 004/2011 and TR CU 020/2011 and OTT -29-020.00-KTH-084-10.                                                       

 



 Functions

– Control over the parameters of the outdoor lighting system;

– Accounting and distribution of electric energy;

– Remote control of automatic circuit breakers operation;

– Protection of lamps and outdoor lighting systems and its components against short circuit currents and overloads;

– Ensuring uninterruptible power supply to lamps and outdoor lighting systems and its elements.

 



Application area

Boards are used in lighting and power installations of industrial, public and administrative buildings and are connected to three-phase networks with grounding systems TN-S, TN-C-S, TN-C according to GOST R 50571.2.
