About This

Master Protection for 160A Systems: Engineered for high-output power demands. This 160Amp MCCB provides the ultimate safeguard for large-scale Solar Systems, battery banks, and high-current industrial circuits. It acts as a rugged master disconnect, shielding your expensive inverters and cables from catastrophic overloads.
Specialized DC Arc Quenching: Safety without compromise. Direct Current doesn't have a zero-crossing, making arcs difficult to extinguish. Our DC Circuit Breaker is built with an advanced internal arc-chute system that pulls the arc away from the contacts instantly, preventing fire hazards and extending the device's service life.
Heavy-Gauge Terminal Reliability: Designed for the thickest cables. The oversized copper-alloy lugs are built to handle the torque and heat of 1/0 AWG or 2/0 AWG wires required for 160Amp service. This ensures a rock-solid, low-resistance connection that stays cool even under continuous high-load operations.
Industrial Thermal-Magnetic Trip: Intelligent response to electrical faults. Featuring a calibrated Thermal-Magnetic mechanism, this breaker prevents "nuisance tripping" caused by ambient heat in solar sheds, while providing instantaneous protection against short circuits—the perfect balance for Other DC Applications like winches or hydraulic pumps.
Molded Case Structural Integrity: Built for harsh environments. The WGM1PV-250 is encased in a high-impact, flame-retardant molded shell. Unlike fragile DIN-rail breakers, this surface-mount 1P DC Circuit Breaker resists vibration and structural stress, making it ideal for mobile RV power grids and industrial off-grid setups.
