Why Choose the ABB EPH-S11108 Protecta Home 8-Way 100 A RCCB Consumer Unit?
The ABB EPH-S11108 is an 8-way, 100 A RCCB-controlled consumer unit from the ABB Protecta Home range, designed for residential and light commercial electrical distribution. 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 8 outgoing circuit ways, the EPH-S11108 provides a compact and practical distribution solution for installations requiring a single RCCB-protected circuit group. The 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 with nominal dimensions of 250 × 270 × 105 mm, the ABB EPH-S11108 combines compact construction with practical circuit organisation. Supplied with the specified factory-fitted RCCB, shrouded busbar, neutral and earth bars, and installation instructions, it provides a convenient platform for professional electrical distribution board assembly.

Reliable 8-Way Electrical Distribution with 100 A RCCB Protection
The ABB EPH-S11108 is designed for electrical installations requiring a compact distribution board with a single incoming residual current protective device. Its 8-way configuration provides space for compatible miniature circuit breakers and other approved modular protection devices, allowing electrical contractors to arrange outgoing circuits according to the 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 current-carrying capacity of the RCCB and should not be confused with its residual current operating sensitivity. The precise residual current sensitivity and RCCB type must be confirmed from the installed device specification and matched to the electrical installation requirements.
Because the EPH-S11108 uses a single RCCB-controlled arrangement, a residual current fault on one outgoing circuit may cause the RCCB to disconnect all circuits supplied through it. Electrical designers should consider this shared protection arrangement when determining circuit allocation and continuity-of-supply requirements.
Importantly, an RCCB does not independently provide overload or short-circuit protection. Appropriate miniature circuit breakers or other compatible overcurrent protective devices must therefore be selected for the outgoing circuits. The incoming RCCB must also have suitable upstream overcurrent protection in accordance with the electrical design and manufacturer instructions.
The RCCB can provide switching and isolation functionality where the installed device is approved and suitable for that purpose. However, the EPH-S11108 is an RCCB-controlled consumer unit rather than a separate 100 A main switch plus RCCB configuration. This distinction is important when selecting the correct ABB Protecta Home model.
The steel enclosure provides a robust housing for the distribution assembly, while its compact 250 × 270 × 105 mm dimensions support practical installation planning. The RAL 7035 finish, factory-fitted RCCB, shrouded busbar and termination bars help provide an organised foundation for a professionally assembled consumer unit.
Final device selection, conductor sizing, earthing arrangements, residual current protection coordination and installation methods must comply with ABB installation instructions and applicable electrical installation regulations, including relevant BS 7671 requirements.

Frequently Asked Questions
What is the ABB EPH-S11108 consumer unit?
The ABB EPH-S11108 is an 8-way Protecta Home consumer unit featuring a 100 A incoming RCCB. It is designed for residential and light commercial electrical distribution installations requiring a single RCCB-protected circuit group.
How many outgoing ways does the ABB EPH-S11108 provide?
The EPH-S11108 provides 8 outgoing circuit ways for compatible modular protective devices. The outgoing circuits are supplied through the consumer unit's 100 A RCCB-controlled arrangement.
Does the ABB EPH-S11108 include a 100 A RCCB?
Yes. The EPH-S11108 is specified with a factory-fitted 100 A residual current circuit breaker. The RCCB provides residual current protection for its associated outgoing circuits, while suitable overcurrent protective devices must be selected separately.
What are the dimensions of the ABB EPH-S11108?
The ABB EPH-S11108 has nominal dimensions of 250 × 270 × 105 mm (height × width × depth). It features a steel enclosure with a RAL 7035 light grey finish.
What is the difference between the ABB EPH-S11108 and an 8-way main switch consumer unit?
The EPH-S11108 incorporates a 100 A RCCB as its incoming protective device, providing residual current protection for the associated outgoing circuits. An 8-way main switch-only consumer unit instead uses a switch disconnector for incoming isolation and does not provide the same built-in RCCB protection.
