Overview
The Slocable MCB 500V 2P 10A DC Solar Isolator is a purpose-built miniature circuit breaker (MCB) engineered to safeguard solar PV systems from overcurrent and short-circuit faults. Rated at 500V DC with a 10-ampere continuous current rating and a robust 6kA short-circuit breaking capacity, this double-pole unit simultaneously disconnects both positive and negative conductors — delivering complete galvanic isolation and full circuit protection in a single compact device. Its thermal-magnetic trip mechanism and C-curve characteristic make it ideally matched to solar PV string protection, while the flame-retardant thermoplastic housing ensures reliability across Australian operating temperatures from -5°C to +40°C.
Purpose-designed for Australian caravan, RV, motorhome, and off-grid 4WD setups, this MCB slots neatly onto a standard 35mm DIN rail inside any distribution enclosure or switchboard — keeping your solar installation tidy and compliant. Use it between solar panels and your MPPT or PWM charge controller to protect against string overcurrent, or between your battery bank and inverter to guard against downstream faults. Compatible with 12V, 24V, and 48V off-grid systems, it also doubles as a convenient manual isolation switch for safe maintenance work on your solar array, making it an essential component for any serious off-road or long-haul touring rig.
