CHTAIXI DC MCB 2P C100 – 500V 100A 35mm DIN Rail DC Isolator for Solar PV Systems

Reliable DC protection for solar and other DC systems

The CHTAIXI DC MCB 2P C100 is a compact two-pole circuit breaker designed for DC power paths up to 500V and 100A. It blends fast protection with reliable isolation, helping to reduce risk in solar PV installations and other DC networks. With a magnetic arc-extinguishing system and durable silver alloy contacts, it aims for steady performance in busy control panels and enclosed spaces. The flame-retardant shell and clear color indicator support quick status checks at a glance, aiding routine maintenance and safer operation.

The unit mounts on a 35mm DIN rail, enabling tidy panel layouts in solar inverters, battery rooms, and DC distribution cupboards. Its robust construction, combined with a practical visual indicator, offers a calm, predictable user experience under typical conditions and during fault events. This combination can be particularly helpful when coordinating protective devices across a DC power chain, from generation to distribution.
