HS1 series circuit breakers are suitable for 50/60Hz AC systems with insulation voltage up to 1000V, an operating voltage of AC 400V/230V, and a rated current ranging from 125A to 400A. They provide integrated protection for both power distribution and motors, with smart options such as the HS1E model that can be installed inside meter boxes and interact with measurement systems, and the HS1M model, designed for versatile applications.

An External Circuit Breaker is a protective switching device designed to interrupt electrical current during overloads, short circuits, or other fault conditions. It is typically installed in outdoor power distribution networks and protects electrical equipment and network sections.
The circuit breaker continuously carries normal operating current and opens the electrical circuit when its protection system detects a fault. Depending on its configuration, it may be operated manually, automatically, or remotely through a compatible control and communication system.
An External Circuit Breaker is designed to interrupt both normal load current and fault current. A Load Break Switch is mainly designed to switch normal load current and isolate network sections. The correct device depends on the network’s protection and switching requirements.
Important factors include rated voltage and current, fault-interruption capacity, insulation level, protection functions, installation environment, operating mechanism, communication capabilities, applicable standards, and project-specific requirements.
The price depends on its voltage and current ratings, interruption capacity, protection system, controller, communication features, accessories, and project requirements. Contact Holystar Arabia for a customized quotation based on your required technical configuration.
