Wengart 200 Amp DC MCCB Circuit Breaker, 250V 1-Pole Molded Case Breaker for High-Capacity Solar Inverters, Battery Bank & Off-Grid Power Systems, WGM1PV-250 Heavy Duty DC Protector

The Heavy-Weight Champion of DC System SafetyWhen you are managing a 200-Amp power flow, there is no room for "good enough." The Wengart MCCB Circuit Breaker WGM1PV-250 is a professional-grade Molded Case solution designed for the most demanding Solar Systems and energy storage grids. Rated for DC250V and below, this 1P breaker is the essential link between your high-capacity battery bank and your off-grid inverter, providing a level of safety and durability that miniature DIN-rail breakers can't match.Engineered for Thermal Stability and Longevity High-amperage DC protection requires specialized engineering to handle heat and electrical arcs. The Wengart 200A breaker utilizes silver-alloy contacts and an optimized internal geometry to keep resistance at an absolute minimum. This means less heat generated during normal operation and faster isolation during a fault. Designed for permanent surface mounting, this breaker is built to be the "Master Disconnect" that you can rely on for years of maintenance-free service.Technical SpecificationsCurrent Rating: 200 Amp (Continuous Duty)Voltage Rating: DC 250V (Works for 12V, 24V, 48V, 72V, 96V, 120V systems)Pole Configuration: 1-Pole (1P)Trip Type: Thermal-Magnetic Precision TripMounting: Surface/Backplate Mounting (Hardware included)Wire Compatibility: Optimized for 4/0 AWG and high-capacity busbarsFrequently Asked Questions (Lowering Your Return Rate)Q: Does it matter which way I wire the "+" and "-"? A: Yes! For maximum safety and arc-quenching performance, please follow the Polarity Markings on the device. We recommend installing this on the Positive leg of your battery circuit.Q: Is this too big for a standard breaker box? A: Most likely. This is a Molded Case Circuit Breaker (MCCB), which is significantly larger than a standard home breaker. Please check the dimensions in the product images to ensure you have adequate clearance in your enclosure.Q: Can this be used as a manual battery disconnect? A: Absolutely. The high-leverage toggle handle is designed for manual operation, allowing you to safely isolate your battery bank for maintenance or during system emergencies.

• Industrial-Scale Power Protection: Secure your high-wattage investments. This 200Amp MCCB is engineered as the ultimate safety backbone for Solar Systems and massive battery arrays. It provides critical overcurrent and short-circuit protection for systems where standard miniature breakers simply cannot handle the thermal load.
• Advanced Magnetic Arc-Quenching: DC power creates persistent arcs that are difficult to break. Our DC Circuit Breaker features specialized internal arc-chutes that rapidly extinguish high-energy arcs, preventing internal carbonization and ensuring a safe, decisive disconnection under full load conditions.
• Heavy-Duty Terminal Engineering: Built for the thickest conductors. The reinforced copper-alloy terminals are designed to accommodate the 4/0 AWG or larger cables required for 200Amp service. This ensures a low-resistance connection, significantly reducing heat buildup at the contact points—a common failure point in budget breakers.
• Rugged Molded Case Construction: Durability for the harshest environments. Housed in a flame-retardant, high-impact molded shell, the WGM1PV-250 is resistant to structural stress and vibration. Whether it’s installed in a static solar shed or a mobile Emergency Command Vehicle, it maintains its calibration and safety rating.
• Precision Thermal-Magnetic Tripping: Reliability without "nuisance trips." Our dual-action mechanism provides instantaneous magnetic protection against short circuits while allowing for the natural inrush currents of large inverters. It’s the professional choice for Other DC Applications like EV charging stations and telecommunications backup power.
