Overview
The Slocable MCB 500V 2P 16A DC Solar Isolator is a heavy-duty 2-pole miniature circuit breaker engineered specifically for direct current photovoltaic systems. Rated at 500V DC and 16A continuous current, it features a dedicated DC arc-quenching chamber with magnetic blow-out technology that ensures safe, reliable interruption of DC fault currents — something standard AC breakers fundamentally cannot do. With a 6kA breaking capacity, Type C trip curve, and compliance to IEC/EN 60947-2, this MCB delivers both overload and short-circuit protection in a compact 35mm DIN-rail format that fits standard electrical enclosures.
Purpose-built for off-grid solar installations in Australian caravans, motorhomes, RVs, and 4WD setups, this isolator handles 12V, 24V, and 48V battery systems with open-circuit voltages up to 500V DC — covering virtually every rooftop solar array configuration used on the road. Its wide operating temperature range of -25°C to +70°C means it performs equally well in the scorching heat of the outback as it does on cold winter mornings in the high country. Whether you're wiring a solar string on a caravan roof, protecting a battery bank in a camper trailer, or building out a reliable off-grid power system for remote camping, the clear ON/OFF toggle and DIN-rail mount make installation and servicing fast and straightforward.
