TNCM1 Moulded Case Circuit Breaker (MCCB)
MCCB (molded case circuit breaker) is a mechanical switchgear that can connect, carry, and disconnect current under normal circuit conditions, as well as connect, carry, and disconnect current for a certain period of time under specified abnormal circuit conditions.
The TNCM1 series moulded case circuit breakers (hereinafter referred to as circuit breakers) are suitable for AC 50Hz (or 60Hz) circuits with rated insulation voltage of1000V (800V for TNCM1-63 and 1140V for TNCM1-1600), rated operating voltage of 400V/690V (1140V for TNCM1-1600) and below, and rated operating current up to 1600A for infrequent switching and infrequent motor starting. The circuit breaker has overload, short circuit, and undervoltage protection functions, which can protect the circuit and power equipment from damage.
Circuit breakers are classified into L-type (standard type) and M-type (high breaking type) according to their rated ultimate short-circuit breaking capacity.This circuit breaker has the characteristics of small volume, high breaking capacity.short arcing, and high vibration resistance.
