Mini Manual Service Disconnect EV Socket 2 Pins Front Mount 400A

Engineered for space-constrained high-voltage environments, our Mini Manual Service Disconnect (Mini MSD) series delivers uncompromised safety in a highly compact, cost-effective footprint. Optimized for Energy Storage Systems (ESS) and Electric Vehicle (EV) battery packs, it reliably handles a 200A to 400A current capacity at 690V/700V DC. Despite its smaller size, it retains all critical safety features—including an integrated High-Voltage Interlock Loop (HVIL), a precise two-stage unlocking mechanism, IP2XB touch-safe design, and built-in replaceable fuses—providing engineers with a foolproof circuit protection and isolation solution tailored for tight installation spaces.

Compact Footprint & Circuit Protection

Optimized for space-constrained battery layouts, this Mini MSD safely handles 200A to 400A at 690V/700V DC. It features a built-in replaceable fuse that instantly isolates electrical faults, protecting your expensive systems from overcurrent damage while saving valuable enclosure space.

Advanced Two-Stage Safety Disconnect

Incorporates a precise two-stage unlocking mechanism synchronized with an integrated High-Voltage Interlock Loop (HVIL) circuit. This design ensures the HVIL circuit completely breaks before the main power contacts separate. It effectively eliminates the risk of dangerous electrical arcing, guaranteeing absolute safety for your maintenance personnel during manual service operations.

IP2XB Touch-Safe Protection

Constructed with a reliable IP2XB touch-safe design across all exposed terminal areas on both the plug and socket. This physical barrier actively prevents operators’ fingers from accidentally contacting live high-voltage components when the device is unmated. It ensures your energy systems meet strict industry safety compliance and prevents fatal shock hazards during routine inspections.

Designed for critical high-power isolation, our Manual Service Disconnect (MSD) connectors are essential safety components for commercial Energy Storage Systems (ESS), Electric Vehicle (EV) battery packs, and high-voltage Power Distribution Units (PDUs). Engineered to handle up to 400A and 700V DC, they provide engineers and service technicians with a secure, tool-free solution to instantly sever high-voltage circuits. This guarantees absolute safety and compliance during system upgrades, routine battery maintenance, and emergency responses.
