Product Description

MCCB Highlights

ARXM3 Series

Alloy contact with high silver content

The second material advantage of ARXM3 thermal magnetic type mccb---- alloy contact with high silver content: the mccb's silver spots' content can reach 85%.
High silver content, high conductivity, thermal conductivity, arc resistance, electric wear resistance.
Preparation of dynamic and static contact material standards and reliable process guarantee, improving the electrical life of circuit breaker by 50%.
