DOS-MV2P80 is a DIN-rail mounted switch isolator designed for electrical distribution and panel applications. It is used to safely isolate a circuit (disconnect it from the supply) for maintenance, testing, or emergency shutdown.

✔ Type: DIN Rail Disconnect / Isolator Switch
✔ Poles: 2 (phase + neutral) → 2P
✔ Rated Current: 80 A → 80
✔ Mounting: Clip-on 35 mm DIN rail
✔ Function: Manual electrical isolation — breaks both poles so the circuit is fully disconnected when OFF

A DIN rail isolator like the DOS-MV2P80 is a manual disconnect switch that:

• Provides a positive break of both phase and neutral lines for safety.

• Enables safe maintenance or servicing of downstream equipment.

• Helps meet electrical safety regulations by clearly separating live parts when OFF.

• Is suitable for use in distribution boards, panel boards, and switchgear assemblies.

It doesn’t usually provide over-current protection like a circuit breaker — its main purpose is circuit isolation, not automatic protection.
