PV Circuit Breaker (1000V-63A-4P)

The PV Circuit Breaker (1000V DC, 63A, 4-Pole) is designed to provide safe, reliable protection for solar photovoltaic (PV) systems operating at high DC voltages. With a 63A current rating and 1000V DC capacity, this breaker is ideal for isolating and protecting your solar strings, combiner boxes, or inverter inputs.

Engineered for use in off-grid, grid-tied, and hybrid solar systems, this 4-pole DC breaker offers enhanced safety by breaking both positive and negative lines simultaneously — minimizing the risk of arcing and electrical faults in high-voltage DC circuits.

Built with high-quality arc-extinguishing materials and quick-trip mechanisms, this circuit breaker helps prevent system damage during overcurrent, short circuits, or system maintenance. It can be DIN rail mounted for quick installation in distribution or combiner boxes.
