Why Choose the ABB EPH-S11110 Protecta Home 10-Way 100 A RCCB Consumer Unit?
The ABB EPH-S11110 is a 10-way, 100 A RCCB-controlled consumer unit from the ABB Protecta Home range, designed for residential and light commercial electrical distribution installations. Featuring a 100 A residual current circuit breaker (RCCB) as its incoming protective device, this consumer unit provides residual current protection and switching for its associated outgoing circuits.
Designed to accommodate 10 outgoing circuit ways, the EPH-S11110 provides a practical distribution solution for installations requiring a single RCCB-protected circuit group. Its factory-fitted 100 A RCCB monitors residual current imbalance and disconnects the protected circuits when its specified operating conditions are met, supporting electrical safety when installed as part of a correctly designed protection system.
Housed in a durable steel enclosure measuring 250 × 290 × 105 mm, the ABB EPH-S11110 combines compact construction with organised circuit distribution. Supplied with a factory-fitted RCCB, shrouded busbar, neutral and earth bars, and installation instructions, it provides a convenient foundation for professional electrical distribution board assembly.

Reliable 10-Way Electrical Distribution with 100 A RCCB Protection
The ABB EPH-S11110 is designed for electrical installations requiring a compact consumer unit with a single incoming residual current protective device. Its 10-way configuration provides space for compatible miniature circuit breakers and other approved modular protection devices, allowing electricians to organise lighting, socket outlet and fixed appliance circuits according to the electrical installation design.
The consumer unit incorporates a 100 A RCCB as its incoming device. Unlike a main switch-only consumer unit, this configuration provides residual current protection for the outgoing circuits connected through the RCCB. The device monitors the balance between outgoing and returning current and disconnects the protected circuits when a qualifying residual current imbalance is detected.
The 100 A rating describes the RCCB's current-carrying capacity and must not be confused with its residual current operating sensitivity. The precise residual current sensitivity and RCCB type should be confirmed from the installed device specification and matched to the requirements of the electrical installation.
Because the EPH-S11110 uses a single RCCB-controlled arrangement, a residual current fault on one outgoing circuit may cause the incoming RCCB to disconnect all circuits supplied through it. Electrical designers should consider this shared protection arrangement when determining circuit allocation, continuity-of-supply requirements and the suitability of the consumer unit for a particular installation.
Importantly, an RCCB does not independently provide overload or short-circuit protection. Suitable miniature circuit breakers or other compatible overcurrent protective devices must therefore be selected for the outgoing circuits. Appropriate upstream overcurrent protection for the RCCB must also be provided in accordance with the electrical design and ABB installation instructions.
The incoming RCCB can provide switching and isolation functionality where the installed device is approved and suitable for that purpose. However, the EPH-S11110 is an RCCB-controlled consumer unit rather than a separate 100 A main switch plus RCCB configuration. This distinction is important when comparing Protecta Home consumer unit models.
The steel enclosure provides a robust housing for the distribution assembly, while its nominal dimensions of 250 × 290 × 105 mm support installation in suitable indoor locations. The RAL 7035 finish, factory-fitted RCCB, shrouded busbar and conductor termination bars help provide an organised foundation for professional electrical distribution.
Final device selection, conductor sizing, earthing arrangements, residual current protection coordination and installation methods must comply with ABB instructions and applicable electrical installation regulations, including relevant BS 7671 requirements.
