### Product Overview
● The CM3 Molded Case Circuit Breaker (hereinafter referred to as the circuit breaker) is an upgraded product of the CM1 series launched by our company. The electronic CM3E series circuit breakers have six current rating frames: 100A, 250A, 400A, 630A, 800A, and 1250A, with currents ranging from 12.5A to 1250A.
● Based on the rated ultimate short-circuit breaking capacity (Icu), the circuit breakers are classified into four levels: Type C (Basic), Type L (Standard), Type M (Higher Breaking Capacity), and Type H (High Breaking Capacity).
● The entire series can be installed horizontally (sideways), vertically (upright), or flat.
● All circuit breakers in the series possess an isolation function, indicated by the symbol: ●1X
Circuit breakers comply with the following standards:
● IEC 60947-1 & GB/T 14048.1-2012 Low-voltage switchgear and controlgear - Part 1: General rules
● IEC 60947-2 & GB/T 14048.2-2008 Low-voltage switchgear and controlgear - Part 2: Circuit-breakers
● IEC 60947-4-1 & GB/T 14048.4-2010 Low-voltage switchgear and controlgear - Part 4-1: Contactors and motor-starters - Electromechanical contactors and motor-starters (including motor protection)
