NYKM Series

Molded Case Circuit Breaker

Compact Safe Wide application Diversity

PRODUCT OVERVIEW

NYKM series molded case circuit breaker features small size, high breaking capacity, multiple specifications and full range of accessories, which is widely used in industrial, commercial, residential and infrastructure projects. It can meet customized needs with highly flexible systems to realize intelligent control and management.

DOUBLE INSULATION DESIGN

Adopts dual insulation design to increase the insulation of the product. The insulation voltage level is 1000V, and the molded case is equipped with standard inter-phase spacer, which makes the electricity safer and more adaptable to various operating scenarios.

FLAME-RETARDANT AND HIGH
TEMPERATURE RESISTANT CASING

Adopts flame-retardant and high temperature resistant casing can effectively protect electrical equipment from the threat of fire and high temperature. We pay attention to details and structural stability in design to ensure that the product can operate normally in various harsh environments.
