Why Choose the ABB EPH-S10020 Protecta Home 20-Way Consumer Unit?

The ABB EPH-S10020 is a 20-way, 100 A main switch consumer unit from the ABB Protecta Home range, designed for residential and light commercial electrical distribution installations. Featuring a factory-fitted 100 A switch disconnector (isolator), this consumer unit provides a central point for isolating the electrical installation while accommodating separately selected circuit protection devices.

Manufactured with a robust steel enclosure, the EPH-S10020 offers a practical solution for electrical installations requiring multiple outgoing circuits. Its 20-way configuration supports organised distribution of electrical circuits for lighting, socket outlets, fixed appliances and other building services. The enclosure is supplied with a shrouded busbar, neutral and earth bars, and installation instructions to support professional assembly.

With nominal dimensions of 250 mm high × 450 mm wide × 105 mm deep, the ABB EPH-S10020 combines generous circuit capacity with a compact, wall-mounted format. Its RAL 7035 light grey steel finish provides a durable appearance suitable for utility areas, electrical cupboards and other appropriate indoor installation locations.

20-Way Electrical Distribution with a 100 A Main Switch

The ABB EPH-S10020 is designed for installations where a substantial number of outgoing circuits must be accommodated within one consumer unit. Its 20-way capacity provides flexibility when arranging separate circuits for lighting, socket outlets, kitchen appliances, heating equipment and other electrical loads.

The factory-fitted 100 A main switch isolator provides a means of disconnecting the consumer unit supply for appropriate isolation procedures. Unlike an RCD or RCBO, a switch disconnector does not independently provide residual current or overcurrent protection. These functions must be provided by suitably selected protective devices according to the electrical installation design.

The steel enclosure provides a robust housing for the electrical distribution assembly. Its RAL 7035 light grey finish is suitable for electrical cupboards, service areas and other locations where a professional, practical appearance is preferred.

The included shrouded busbar, neutral bar and earth bar support the assembly and wiring of compatible circuit protection equipment. The arrangement helps electricians maintain organised conductor routing and provides convenient termination points for outgoing circuit conductors.

As part of ABB's Protecta Home range, the EPH-S10020 is intended for use with appropriately selected and approved electrical protection devices. Final circuit arrangements, RCD or RCBO requirements, conductor sizes and installation methods must be determined in accordance with applicable wiring regulations and ABB's installation instructions.
