63A 32A MCCB Circuit Breaker 50Hz 3 Phase Circuit Breakers For Industrial Power Distribution
The MKB6, MKB6E, MKB6EL series of circuit breakers are upgraded models developed by our company, combining international product advantages with domestic and international market requirements. With an insulation voltage up to 1000V, these breakers are designed for:
- AC distribution systems at 50Hz frequency
- Rated working voltage of 690V
- Current range from 10A to 800A
These circuit breakers provide protection against overload, short circuit, and under voltage conditions. They can also be used for infrequent motor startup operations while offering protection against electrical faults. Key features include compact size, high breaking capacity, and short flashover protection.
The YOM6DC series DC moulded-case circuit breaker is suitable for DC systems with voltage up to 1000V and current from 10A to 800A, offering protection against overload and short circuit conditions. Compliant with IEC60947-2 and GB14048.2 standards.
