Why Choose the Mersen 4P1600 Neutral-Pole Switch Accessory?
The Mersen 4P1600 is a dedicated neutral-pole accessory designed for compatible Mersen M1600 non-fusible disconnect switches. It allows a three-pole M1600 switch assembly to be configured for four-pole operation where the neutral conductor must be switched and isolated alongside the three phase conductors.
Engineered as part of Mersen's modular disconnect-switch system, the 4P1600 operates mechanically with the main switch mechanism to provide coordinated isolation. This makes it suitable for high-current industrial switchboards, power-distribution panels and machinery installations requiring simultaneous disconnection of all phases and the neutral.
The accessory is specifically designed for the Mersen M1600 UL 98 switch platform and must be installed as part of a complete compatible disconnect-switch assembly. Its heavy-duty construction supports dependable operation within demanding industrial and commercial power-distribution environments.
Key Advantages
- Adds a dedicated switched neutral pole to a compatible Mersen M1600 disconnect switch.
- Enables coordinated four-pole isolation of three phases and neutral.
- Designed specifically for the high-current M1600 switch platform.
- Modular construction simplifies switchboard and panel configuration.
- Suitable for industrial power-distribution and service-isolation applications.
- Manufactured by Mersen for dependable mechanical compatibility.
Key Features
- Mersen 4P1600 neutral-pole accessory.
- Compatible with Mersen M1600 UL 98 non-fusible disconnect switches.
- Provides one additional switched pole.
- Designed primarily for neutral conductor switching.
- Mechanically coordinated with the main disconnect-switch mechanism.
- Enables a compatible three-pole switch to operate as a four-pole assembly.
- Heavy-duty construction for high-current switchgear applications.
- Accessory component rather than a complete disconnect switch.
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 isolation is specified.
The Mersen 4P1600 is engineered for coordinated operation with the compatible M1600 disconnect-switch mechanism. It should only be installed with the specified switch platform and in accordance with Mersen installation instructions, applicable wiring regulations and the requirements of the complete power-distribution system.
Typical Applications
- Three-phase and neutral power-distribution systems.
- Industrial switchboards and distribution panels.
- Service-isolation switch assemblies.
- Generator and transfer-switch installations.
- Large machinery isolation systems.
- Commercial and industrial electrical distribution equipment.
