FuseBox 2 Pole 100A Main Switch Enclosed IP20 Meter Isolator | E2PMSH

Compact 100A Double Pole Main Switch for Meter Tail Isolation

The FuseBox E2PMSH is a compact 2 pole 100A enclosed main switch and meter isolator, designed to provide a convenient point of isolation between the electricity meter and consumer unit.

Rated at 100A AC22A, the E2PMSH simultaneously isolates both conductors in a single-phase installation and is specifically designed for use with 16mm² and 25mm² double-insulated meter tails. Its compact IP20 polycarbonate enclosure makes it ideal for indoor meter cupboards, service positions and other locations where space is limited.

The enclosure also features a split cover, top and bottom cable entry points and wire-sealing provision, providing a practical, installer-friendly solution for meter isolation and main switching applications.

100A Double Pole Isolation

The E2PMSH incorporates a 2 pole 100A main switch, allowing both conductors to be disconnected when the isolator is operated.

This provides a convenient means of isolating the electrical installation downstream of the meter, allowing work to be carried out without routinely needing to disturb the upstream supply fuse.

With a rated operational current of 100A AC22A, the unit is suitable for appropriately designed installations up to its specified rating.

Designed for Meter Tails

FuseBox specifically designs the E2PMSH for use with 16mm² and 25mm² double-insulated meter tails.

The main switch terminals can accommodate conductors up to 35mm², providing generous connection capacity, while top and bottom entry points help simplify cable routing during installation.

Compact IP20 Polycarbonate Enclosure

The main switch is supplied ready-mounted inside a compact IP20 polycarbonate enclosure.

At approximately 150mm high, 50mm wide and 83mm deep, the E2PMSH requires relatively little wall space, making it particularly useful for meter cupboards and service areas where installation space may be restricted.

The enclosure is intended for indoor installation.

Split Cover with Wire-Sealing Facility

The E2PMSH features a practical split-cover enclosure with provision for a wire or plastic seal through the tamper-resistant screw.

This makes the unit particularly well suited to meter isolation applications while providing straightforward access during installation and authorised maintenance.

High Mechanical Endurance

FuseBox specifies the E2PMSH with a mechanical endurance of 20,000 operations, providing a durable switching solution for long-term installation.

The unit is designed to operate across temperatures from -25°C to +40°C, with a specified storage range of -25°C to +70°C.
