About This

Industrial-Grade 250A Protection: Engineered for the most demanding energy storage systems. This 250Amp MCCB provides a robust safety barrier for high-power Solar Systems, capable of handling the massive current flow from large battery banks to 10kW+ inverters. It is the definitive upgrade for users moving beyond the limits of standard miniature breakers.
Superior Magnetic Arc-Quenching: Safety without compromise. DC currents are notoriously difficult to interrupt; our DC Circuit Breaker features a specialized internal arc-chute and permanent magnet system that pulls the arc away from the contacts instantly. This ensures a clean, safe disconnect and prevents internal carbon buildup during a fault.
Heavy-Duty Terminal Integrity: Built for the thickest conductors. The oversized copper terminals are designed to accommodate high-gauge cables (up to 250kcmil or 4/0 AWG) with ease. This high-torque connection point minimizes electrical resistance and prevents the heat-related terminal melting often seen in lower-quality DC Applications.
Molded Case Ruggedness: Engineered for longevity in harsh environments. The WGM1PV-250 is housed in a high-impact, flame-retardant molded shell that protects internal precision components from structural vibration and dust. It’s the ideal DC Master Disconnect for static home powerwalls or mobile command centers.
Reliable Master Disconnect Function: Total control at your fingertips. The high-leverage toggle handle provides a clear tactile response, allowing you to use this breaker as a primary manual disconnect for your Battery Bank. Whether for emergency isolation or routine maintenance, it ensures your high-voltage DC grid remains under your absolute control.
