DC MCB Schneider C65H-DCC10A | Multi 9 Protection Module

Schneider C65H-DCC10A Miniature DC Circuit Breaker

Product Description
The Schneider C65H-DCC10A is a compact DC miniature circuit breaker built for stable performance in low-voltage direct current protection systems. It delivers consistent 10 A protection with a C-curve trip profile, making it suitable for DC circuits that experience moderate inrush currents. Moreover, its high 10 kA breaking capacity at 250 V DC ensures reliable interruption during fault conditions.

Engineers value this breaker for its robust endurance, long service life, and dependable thermal-magnetic tripping behavior. In addition, its flame-retardant housing and 35 mm DIN-rail mounting simplify panel design while maintaining safety compliance with IEC 60947-2 and GB 14048.2. The breaker performs well in solar systems, industrial DC panels, and energy storage applications where fault isolation must be quick and predictable.
