Mold Case Circuit Breaker (JCM1E)

Description/Feature/Scope of Application

The JCM1E-M series electronic plastic case circuit breakers, referred to as circuit breakers, are designed for AC systems at 50Hz (or 60Hz), rated insulation voltage of 800V, and working voltage up to 690V, with a rated working current of up to 800A. They manage infrequent motor switching and starting, providing overload and short-circuit protection, including under-voltage protection, with optional residual current and phase loss protection. Classified as M type (higher breaking capacity) or H type (high breaking capacity), they feature compact size, high breaking capacity, short arcing, and anti-vibration properties, suitable for vertical or horizontal installation. The circuit breakers offer isolation functionality and must be correctly oriented during installation, connecting power lines to terminals 1, 3, and 5, and load lines to terminals 2, 4, and 6.The JCM1E-M series electronic plastic case circuit breakers, referred to as circuit breakers, are designed for AC systems at 50Hz (or 60Hz), rated insulation voltage of 800V, and working voltage up to 690V, with a rated working current of up to 800A.
