Why Choose the Mersen NP80 Neutral Pole Accessory?
The Mersen NP80 is an additional neutral pole accessory designed for use with compatible Mersen M63 and M80 non-fused disconnect switches. It allows a compatible three-pole switch assembly to be expanded with a fourth switched pole, making it suitable for electrical systems where the neutral conductor must be isolated alongside the phase conductors.
Designed for industrial control panels, machinery and power distribution equipment, the NP80 provides reliable mechanical and electrical integration with the associated Mersen disconnect switch platform. Its compact construction helps panel builders create coordinated isolation assemblies without requiring a separate neutral switching device.
The NP80 has a rated current of 80 A and a general-use voltage rating of up to 600 V AC. It is supplied as an accessory rather than a complete disconnect switch and must be installed with a compatible Mersen switch body and operating components.

Coordinated Neutral Isolation for Industrial Switches
The Mersen NP80 enables a compatible three-pole disconnect switch to incorporate an additional switched neutral pole. This allows the neutral conductor to be disconnected in coordination with the phase conductors when required by the equipment design, maintenance procedure or applicable electrical installation standard.
Because the NP80 is designed for the associated Mersen switch platform, it provides a compact and mechanically coordinated solution for panel builders and OEM manufacturers. Compatibility should be confirmed against the exact disconnect switch model before installation.
Typical Applications
- Industrial control panels.
- Machinery disconnect assemblies.
- Electrical distribution boards.
- OEM automation equipment.
- Three-phase systems requiring neutral isolation.
- Motor control and maintenance isolation circuits.
