Schneider C65H-DCC6A Miniature Circuit Breaker

Product Overview

The Schneider C65H-DCC6A is a specialized 2-pole miniature circuit breaker (MCB) from the Multi 9 C65H-DC series, purpose-built for low-voltage direct current applications. In DC environments, extinguishing an electrical arc is significantly more challenging than in AC systems; this breaker is specifically engineered with magnetic arc-extinguishing technology to handle those risks.
