Schneider C65H-DCC10A Circuit Breaker

Product Overview

The Schneider C65H-DCC10A is a specialized DC miniature circuit breaker (MCB) from the C65H-DC (Multi9) series. Engineered specifically for direct current protection, this 2-pole breaker is designed to safeguard DC distribution networks, renewable energy systems (such as solar PV arrays), and industrial automation equipment. Unlike standard AC breakers, the C65H-DC series is built to handle the unique extinguishing requirements of DC arcs, ensuring reliable performance in systems up to 250 VDC.

Key Features

• Dedicated DC Protection: Specifically designed to manage DC current, which does not have a natural "zero-crossing" like AC, making it essential for battery banks and solar power strings.

• C-Curve Tripping Profile: Optimized for standard industrial loads, providing a balance between protecting sensitive electronics and allowing for minor inrush currents.

• High Breaking Capacity: Rated for 10 kA, ensuring the breaker can safely interrupt significant fault currents without damage to the surrounding infrastructure.

• Compact DIN Rail Mounting: Standard 36mm width (2 modules) allows for easy integration into standard electrical panels and distribution boards.

• Tunnel-Type Terminals: Features robust terminals designed for secure cable clamping, reducing the risk of loose connections and thermal hotspots.

• Visual Status Indication: Provides clear "ON/OFF" status via the toggle handle and front-facing indicators for rapid troubleshooting.

• Global Standards Compliance: Certified to IEC 60947-2, UL, and CCC standards, making it suitable for international industrial projects.
