Suntree 20 Amps DC MCB Solar Breaker 4 Pole 1000V

Product Description

Keep your solar strings firing on all cylinders with the Suntree 20A solar circuit breaker – a compact powerhouse that delivers top-notch protection for high-voltage PV setups without the bulk or hassle. This 4-pole miniature circuit breaker is engineered for DC solar applications, capping out at 20A and a whopping 1000V to shield against overloads, shorts, and faults in multi-string arrays, inverters, or battery banks. Polarity? No sweat – it’s reversible for foolproof wiring, even if you’re juggling positive and negative lines in tight spots. With a solid 6kA breaking capacity, it quenches arcs lightning-fast to save your gear from meltdown, all while snapping onto a standard DIN rail for that pro-grade panel look. The thermal-magnetic trip (C curve for those inrush-heavy solar loads) and transparent window for status peeks make it a dream for installers who value speed and smarts. Whether you’re topping off a rooftop farm or beefing up an off-grid rig, this Suntree breaker brings the reliability that turns potential headaches into hassle-free power – day in, day out.
