Low Voltage Molded Case (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.

FAQ Smart Load Break Switch

A Smart Load Break Switch is a medium-voltage switching device used to open and close electrical circuits under normal load conditions. Smart models can also support remote monitoring, control, and integration with distribution automation systems.

A Load Break Switch interrupts the normal operating current using a switching and arc-extinguishing mechanism. It allows operators to connect or isolate sections of a distribution network safely during normal operating conditions.

A Load Break Switch is primarily designed to switch normal load current, while a circuit breaker is designed to interrupt both normal current and fault current. The appropriate device depends on the network’s switching, protection, and fault-interruption requirements.

Key considerations include rated voltage, rated current, short-circuit withstand capability, insulation level, installation environment, operating mechanism, communication requirements, automation capabilities, and compliance with the project’s applicable standards.

The price depends on the rated voltage and current, controller, communication system, installation type, automation features, accessories, and project requirements. Contact Holystar Arabia for a quotation based on your required technical configuration.
