Braking Resistor Box Rated Power 120kw

Braking Resistor Box Rated Power 120kw

The BRB series resistors are resistor boxes that assembled with wirwound braking resistors and can be suitable for rugged applications with very high power rating. This resistor group is designed for heavy duty and harsh conditions such as elevators, cranes or for braking of big electrical motors. This type has capability to withstand overload for a long time without any damage. Furthermore the power limits indicated ensure that the temperature doesn't damage other components nearby. It also ensures stability and reliability.

Key Features:
1.Long term high stability and reliability;
2.No thermal drift ;
3.high power ratings(up to 36KW) and large current value application;
4.terminals suitable for soldering or bolt connection.

Characteristics of this series:
1.Rated power: 2KW to 36KW, based on 25℃ free air rating( to 100 KW on request);
2.Resistance values: from 1Ω to as high as 10 KΩ( to 100 KΩ on request);
3.Temperature Coefficients:25,50 ,100 and 400ppm/℃ or as required;
4.Operating Temperature:-55℃ to +225℃;
5.Insulation Resistance: >100MΩ (500V 25℃ 75% relative humidity);
6.Dielectric strength: >3.0KV 50Hz 1min(25℃ 75% relative humidity);
7.IP protection: IP00, IP20, IP23 or as required;
8.Element material: OCR25AL5/CrAlFe/CrNi/CuNi;
9.Lead material: Brass Caps(lug terminations available);
10.Encapsulation: Silicone conformal coating.

Application:
1.inverter braking equipment or motors;
2.testing load,;
3.crane systems, various steel mill applications ;
4.elevator,lift systems, available through distribution;
5.transit applications, neutral grounding.
