Engineered for the highest level of safety in high-voltage Energy Storage Systems (ESS) and Electric Vehicles (EV), our Manual Service Disconnect (MSD) series delivers robust power handling with a 500A to 630A current capacity at 800V DC. Featuring an integrated High-Voltage Interlock Loop (HVIL), a precise two-stage unlocking mechanism, an IP2XB touch-safe design, and built-in replaceable fuses, these highly durable connectors provide engineers with a circuit protection and isolation solution during both active operation and routine maintenance. High-Capacity Power & Circuit Protection Engineered to safely handle massive power loads with a 500A to 630A rated current at 800V DC. It features a built-in replaceable fuse that immediately isolates electrical faults when an overload occurs. This integrated protection effectively safeguards your expensive battery packs and high-voltage power distribution systems from severe overcurrent damage. 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. APPLICATIONS 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 630A and 800V 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.

COMPLIANCE & CERFITICATIONS All certifications listed below are held by Renhotec or our verified manufacturing facilities, ensuring full compliance with international automotive and safety standards. IATF-16949 ISO 9001 Cerfitied CE Compliance RoHS Compliant TUV Safety Tested FAQ What is the operating temperature range and environmental durability of the MSD? Designed for extreme operational environments, the housing is molded from high-grade UL94 V-0 flame-retardant plastics. It maintains stable electrical performance and physical integrity in severe temperatures ranging from -40℃ to 125℃, ensuring reliable operation in both scorching outdoor ESS setups and freezing EV conditions. ? How many mating cycles can this connector withstand safely? While Manual Service Disconnects are typically used only during periodic maintenance or emergencies, our MSD series is built for longevity. The premium contacts ensure a mechanical lifespan of at least 50 safe mating cycles under no-load conditions without degrading the contact resistance or IP sealing. What panel mounting options are available for the MSD receptacle? Our MSD sockets are designed for highly adaptable Panel Mount installations on your Power Distribution Units (PDU) or battery enclosures. Depending on your specific structural design and space constraints, they support both Front Mount (installed from the outside in) and Rear Mount (installed from the inside out). This flexibility ensures a robust integration that withstands severe mechanical vibrations in heavy-duty applications. What is the standard lead time for your connectors? For in-stock items, orders are typically processed and shipped within 1-2 business days. For standard configurations requiring new production, our agile manufacturing capabilities allow us to deliver in as fast as 7 to 14 days.
