Product Introduction

NKM2-400 3P

NKM2 series mccb circuit breaker , whose rated insulation voltage is 800V, is suitable for AC 50 Hz/ 60Hz, rated working voltage AC380V / 400V / 415V, AC660V / 690V, and rated operating current up to 1250A circuit. The MCCB has overload, short circuit and undervoltage protection functions, which can improve the reliability and continuity of power supply and protect power equipment from damage. According to the rated limit short-circuit breaking capacity, MCCB are divided into L type (standard type) , M type (higher breaking type) and H type (high breaking type).
