Series Overview
Main Purpose and Scope of Application
The HYMIK series Molded Case Circuit Breakers (hereinafter referred to as circuit breakers) are new types of circuit breakers developed by our company by comprehensively adopting internationally advanced technologies. Their rated insulation voltage is up to 800V (500V for HYMIK-63). They are suitable for use in distribution networks with an AC frequency of 50Hz, a rated operational voltage up to 690V (400V for HYMIK-63), and a rated operational current up to 1250A. They are used for distributing electrical energy and providing overload, short-circuit, and under-voltage protection for lines and power supply equipment. They can also be used for infrequent switching of lines and infrequent starting of motors (utilization category AC-1), as well as providing overload, short-circuit, and under-voltage protection for motors.
• According to the level of their rated ultimate short-circuit breaking capacity (Icu), the circuit breakers are classified into three types: L Type (Standard), M Type (Higher Breaking Capacity), and H Type (High Breaking Capacity). This product features compact size, high breaking capacity, short arcing distance, and vibration resistance.
• This product complies with the standard GB/T 14048.2 "Low-voltage switchgear and controlgear - Part 2: Circuit-breakers".
Circuit Breakers are suitable for the following operating environments:
• Ambient Air Temperature
