Wengart 250A DC MCCB Circuit Breaker, 2-Pole 500Vdc Molded Case Breaker for 48V Solar Battery Storage, High-Capacity Off-Grid Systems and Inverter Disconnect, WGM1PV-250

Professional-Grade MCCB Protection: Designed for high-amperage, main-system protection. This 250A Molded Case Circuit Breaker (MCCB) is engineered for heavy-duty DC applications. Note: This is a large bolt-on industrial breaker, not compatible with standard 35mm DIN rail residential panels.
Optimized for 48V Battery Banks: The preferred choice for a master disconnect in large-scale energy storage. Whether you are managing a DIY LiFePO4 server rack battery system or an off-grid cabin PV array, this 250A breaker provides the essential fail-safe for your high-current "Hydro" backbone.
Superior 500Vdc Arc Quenching: Built specifically for the challenges of Direct Current. Features internal arc-extinguishing technology that safely interrupts high-energy faults up to 500Vdc, protecting your expensive hybrid inverters and solar panel strings from catastrophic damage.
Rugged Construction for Canadian Climates: Housed in high-impact, flame-retardant molded material that remains stable across extreme temperature fluctuations. Perfect for installation in unheated power sheds, garages, or outdoor enclosures common in North American off-grid setups.
Heavy-Duty Terminal Connections: Features robust, high-torque screw terminals designed to accommodate large-gauge power cables (ideal for 4/0 AWG and above). This ensures a low-resistance connection, minimizing heat buildup and maintaining system efficiency under continuous 250A loads.
