Reliable Main Switch Isolation and Circuit Distribution

The ABB EPH-S10004 Protecta Home consumer unit provides a central location for electrical supply isolation and outgoing circuit protection. Its factory-fitted 100 A main switch-disconnector enables manual isolation of the consumer unit supply, supporting safe electrical installation and maintenance procedures when used in accordance with applicable isolation requirements.

The consumer unit incorporates a shrouded busbar arrangement for distributing the incoming supply to compatible outgoing protective devices. Dedicated neutral and protective earth terminal bars provide organised conductor termination, helping installers maintain a tidy and accessible wiring arrangement within the enclosure.

The 4-way configuration is particularly useful for smaller electrical installations, dedicated distribution requirements and applications where a limited number of final circuits need individual protection. Compatible MCBs provide overcurrent protection, while appropriately selected RCBOs can provide combined overcurrent and residual current protection. The factory-fitted main switch is an isolation device and does not itself provide overload, short-circuit or residual current protection.

The ABB Protecta Home consumer unit family is designed to BS EN 61439-3, covering low-voltage distribution boards intended to be operated by ordinary persons. The completed installation must comply with applicable electrical installation requirements, including BS 7671. Correct selection of protective devices, conductor sizes, earthing arrangements and upstream protection is essential for safe operation.

Typical Applications

• Residential electrical distribution and consumer unit installations.
• Small domestic electrical distribution boards.
• Garages, workshops and utility areas requiring dedicated circuit distribution.
• Residential extensions and refurbishment projects.
• Light commercial premises with limited outgoing circuit requirements.
• Small offices and ancillary building electrical installations.
• Electrical distribution systems using compatible ABB MCBs and RCBOs.
• Replacement and upgrading of suitable existing consumer units.
• Indoor building services installations requiring a compact 100 A main switch consumer unit.
