Why Choose the Mersen 4P2500 Neutral-Pole Switch Accessory?
The Mersen 4P2500 is a heavy-duty neutral-pole accessory designed for use with compatible Mersen M2500 non-fusible disconnect switches. It enables a three-pole M2500 switch assembly to be configured for four-pole operation where the neutral conductor must be switched and isolated together with the three phase conductors.
Engineered for Mersen's high-current UL 98 disconnect-switch platform, the 4P2500 operates mechanically with the main switch mechanism to provide coordinated isolation. This makes it suitable for large industrial switchboards, power-distribution systems and critical electrical installations requiring simultaneous disconnection of all phases and the neutral.
Designed for the 2500 A M2500 switch platform, this accessory provides a practical modular solution for creating a four-pole isolation arrangement. The 4P2500 is supplied as an accessory component and must be installed as part of a compatible complete Mersen disconnect-switch assembly.
Key Advantages
- Adds a dedicated switched neutral pole to a compatible Mersen M2500 disconnect switch.
- Enables coordinated four-pole isolation of three phases and neutral.
- Designed specifically for the heavy-duty 2500 A M2500 switch platform.
- Modular construction simplifies switchboard and distribution-system configuration.
- Suitable for demanding industrial and commercial power applications.
- Manufactured by Mersen for reliable mechanical compatibility with the main switch assembly.
Key Features
- Mersen 4P2500 neutral-pole accessory.
- Compatible with Mersen M2500 non-fusible disconnect switches.
- Provides one additional switched pole.
- Designed for neutral conductor switching and isolation.
- Mechanically coordinated with the main disconnect-switch mechanism.

Coordinated Neutral Isolation for High-Current Systems
A neutral-pole accessory allows the neutral conductor to be disconnected at the same time as the three phase conductors. This arrangement may be required in generator systems, transfer applications, separately derived supplies and other installations where complete four-pole electrical isolation is specified.
The Mersen 4P2500 is engineered to operate as part of the compatible M2500 disconnect-switch mechanism. Installation should be completed in accordance with Mersen documentation, applicable electrical regulations and the technical requirements of the complete switchboard or power-distribution system.
Typical Applications
- High-current three-phase and neutral distribution systems.
- Industrial switchboards and main distribution panels.
- Service-entrance disconnect assemblies.
- Generator and transfer-switch installations.
- Large industrial machinery isolation systems.
- Commercial and industrial power-distribution equipment.
