Overview
The Slocable MCB500322P is a double-pole (2P) miniature circuit breaker purpose-built for DC solar PV systems, rated at 500V DC and 32A continuous with a 6kA short-circuit breaking capacity. Its thermal-magnetic trip mechanism delivers dual-layer protection — reacting to sustained overloads and instantaneous fault currents — while IEC 60947-2 compliance ensures it meets the same international standard demanded in professional solar installations. The compact DIN rail profile (35mm) fits neatly inside standard solar distribution enclosures, keeping your electrical system tidy and safe.
Ideal for Australian caravan owners, motorhome travellers, RV setups, and 4WD dual-battery systems, this isolator is the practical choice wherever a reliable DC disconnect point is needed between solar panels and MPPT charge controllers or battery banks. Whether you're setting up a rooftop solar array on a caravan in the outback, integrating a high-voltage PV string in an off-grid cabin, or building a hybrid system for extended remote travel, the MCB500322P gives you a clean, code-compliant isolation point rated for Australia's demanding conditions — from alpine cold (-25°C) to the scorching heat of the Australian summer (+70°C).
Key Features
- Double-pole (2P) design disconnects both DC positive and negative conductors simultaneously for safe, complete isolation
