Mersen 4P1600 neutral-pole accessory for compatible M1600 UL 98 non-fusible disconnect switches, enabling coordinated four-pole isolation of three phases and neutral.
£961.73
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.
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.
