LV Molded Case CB (MCCB)

The HS1 series low voltage molded circuit breaker is designed to operate on 50/60Hz AC, with a rated insulation voltage of 1000V, operating voltage AC400V/230V, and current capacity from 20a to 600A. The breaker provides reliable protection for electrical power distribution and protection of engines. The HS1E is also intended for use in measuring boxes since it can interact with the meter and receive commands, such as query and control. Therefore, the HS1M is a generic version for multiple uses.
