C-MSD Non-fused Connector

The C-MSD (Compact Manual Service Disconnect) is a safety isolation device specifically designed for high-voltage systems. It is typically used to manually disconnect high-voltage circuits, ensuring operator safety during service, maintenance, or emergency power-off situations. Its compact design, reliable performance, and clear safety functions make it an indispensable component in modern electrical systems, particularly in electric vehicles (EVs), energy storage systems (ESS), and industrial equipment.

Product Characteristics:

Featuring a unique busbar heat dissipation structure, it effectively extends the service life of the fuse. The two-stage unlocking mechanism provides sufficient system response time.

Remarks:

1. Receptacle interlocks are supplied with a wire harness (optional quantities available); the plug is equipped with two high-voltage interlock (HVIL) pins.

2. Use M5 combination bolts for panel mounting. Tightening torque: 4.0–4.3 N·m. Recommended panel thickness: 2–4 mm; Flatness: < 0.1 mm.

3. Use M8 combination nuts for busbar connection. Tightening torque: 14–15 N·m. Fasteners must be tightened using a power driver featuring an instantaneous torque cut-off function (providing an immediate stop and an audible "click" at the set torque). The use of non-torque-controlled power tools is prohibited. If a compliant power driver is unavailable, a calibrated manual torque w
