Industrial RC-MSD2-400-H-B1 Manual Service Disconnector

The RC-MSD2-400-H-B1 Manual Service Disconnector is a high‑current, plug‑and‑jack style disconnect designed for electric vehicle power systems. This Recodeal MSD2 module combines manual disconnection with fuse‑based protection to interrupt high‑voltage circuits during service or maintenance in EV/HEV applications. Key specs include a 750 V DC voltage rating, a nominal current rating of 250 A (300 A for up to 30 minutes), and IP68 sealing after installation (IPXXB option available separately) to resist moisture and dust in automotive environments. The MSD2 platform uses a rotatable locking handle with a secondary lock mechanism for secure operation, and it integrates breaking and fuse elements to save space and simplify servicing. Electrical performance features a total power contact resistance of ≤1.5 mΩ and a signal contact resistance ≤10 mΩ, with insulation resistance of ≤3500 MΩ in normal conditions (100 MΩ under damp heat). Construction materials include a flame‑retardant thermoplastic shell, silver‑plated copper alloy contacts, and silicone rubber seals, with an operating temperature range of −40°C to +125°C and relative humidity up to 95% (40°C). The MSD2 family is rated for around 500 mating cycles, making it suitable for frequent maintenance tasks in EV charging, battery management, and high‑voltage distribution within industrial or automotive systems.
