The Suntree DC MCCB (Molded Case Circuit Breaker) 2 Pole 500VDC is a heavy-duty safety switch designed to protect solar photovoltaic (PV) arrays, commercial solar inverters, and large battery storage systems from electrical overloads and short circuits.

Unlike smaller DIN-rail Miniature Circuit Breakers (MCBs), an MCCB provides much higher current ratings (often ranging from 100A up to 250A) and significantly higher short-circuit interrupting capabilities to safely snuff out high-energy DC arcs.

Suntree DC MCCB (Molded Case Circuit Breaker) 2 Pole 500VDC Key Specifications & Features

Voltage Rating: 500V DC (engineered specifically for mid-voltage DC solar strings or high-capacity battery banks).
Configuration: 2-Pole (Double Pole) to isolate both the positive (+) and negative (-) legs of your DC circuit simultaneously.
Enclosed Arc Chamber: Built with zero-arc-flash technology, meaning it handles internal faults safely without requiring extra partition plates inside your electrical cabinet.
Rugged Mechanical Life: Built to withstand up to 10,000 mechanical operations for frame sizes under 250A.
Extreme Temp Endurance: Operates reliably in environmental conditions ranging from -20°C to 70°C .

Critical Installation Warnings

Polarity Sensitivity: DC MCCBs are strictly polarity-sensitive . You must line up the positive (+) and negative (-) wires coming from your panels or batteries exactly with the stamped markings on the breaker. Reversing the polarity will prevent the internal magnetic chutes from extinguishing an electrical arc, creating a serious fire hazard.
Sizing Safety Margin: When matching this breaker to your solar array, always calculate 125% of the total short-circuit current (Isc) of your solar strings to avoid nuisance tripping from normal peak sun exposure.
