Why Choose the ABB EPH-S11104 Protecta Home 4-Way 100A RCCB Consumer Unit?
The ABB EPH-S11104 (1TVC151800S3099) is a compact 4-way consumer unit with a factory-fitted 100 A residual current circuit breaker (RCCB), designed for residential and light commercial electrical distribution. Part of the ABB Protecta Home range, this consumer unit provides a practical solution for installations requiring four outgoing circuit ways and a common residual current protective device.
Unlike a main switch-only consumer unit, the ABB EPH-S11104 uses a 100 A RCCB as its incoming switching and residual current protection device. This arrangement allows compatible outgoing circuits to be supplied through a single RCCB, providing residual current protection while retaining a convenient means of manual switching. The four-way layout is particularly useful for smaller electrical installations, dedicated circuit groups and distribution board upgrades.
Manufactured with a durable steel enclosure finished in RAL 7035 grey, the EPH-S11104 has nominal dimensions of 250 × 190 × 105 mm (H × W × D). ABB's Protecta Home range is designed to BS EN 61439-3 and is supplied with a shrouded busbar, neutral and earth terminal bars, and installation instructions, helping professional installers create an organised and compliant electrical distribution assembly.

Understanding the 100A RCCB Incomer and Four-Way Circuit Configuration
The ABB EPH-S11104 is part of the 100 A RCCB incomer range of Protecta Home consumer units. Its factory-fitted RCCB monitors the current flowing through the conductors it protects and disconnects the supply when a residual current imbalance exceeds the device's specified operating threshold. This provides an important protective function for suitably designed electrical installations.
The 100 A rating refers to the RCCB's rated current and must not be confused with its residual operating current. The RCCB's residual operating current, type and other protective characteristics must be verified from the fitted device's technical information. An RCCB does not independently provide overload or short-circuit protection, so appropriate upstream protection and correctly selected outgoing overcurrent protective devices are essential.
With four outgoing ways, the EPH-S11104 offers greater circuit capacity than the two-way EPH-S11102 while retaining the same nominal enclosure dimensions. The included shrouded busbar, neutral terminal bar and earth terminal bar help installers organise electrical connections and install compatible outgoing protective devices according to ABB's approved assembly arrangements.
Because the outgoing circuits share a common RCCB incomer, an RCCB operation may disconnect all circuits supplied through that device. Installers should therefore consider circuit continuity, expected protective conductor currents and the requirements of BS 7671 when designing the installation. The completed assembly must comply with ABB's installation instructions and the applicable electrical safety requirements.
Typical Applications
- Small residential electrical distribution installations.
- Domestic consumer unit replacements and electrical upgrades.
- Dedicated groups of circuits requiring common residual current protection.
- Residential refurbishment and renovation projects.
- Garages and domestic workshops with several outgoing circuits.
- Utility rooms and ancillary building electrical distribution.
- Small offices and light commercial premises.
- Indoor distribution systems requiring four outgoing circuit ways.
- Electrical installations using compatible ABB modular protective devices.
- Projects requiring a compact steel consumer unit with a factory-fitted 100 A RCCB incomer.

Frequently Asked Questions
What is the ABB EPH-S11104 used for?
The ABB EPH-S11104 is a 4-way Protecta Home consumer unit with a factory-fitted 100 A RCCB incomer. It is designed for residential and light commercial electrical distribution where compatible outgoing circuits require a common residual current protective device.
How many outgoing ways does the ABB EPH-S11104 provide?
The EPH-S11104 provides four outgoing ways and four modular positions, as identified in ABB's Protecta Home consumer unit selection information. The protective devices installed must be compatible with the manufacturer's approved assembly arrangement.
What is the rating of the RCCB in the ABB EPH-S11104?
The EPH-S11104 incorporates a 100 A RCCB incomer. This figure is the device's rated current, not its residual operating current. The residual operating current must be confirmed from the fitted RCCB specification.
Does the ABB EPH-S11104 include a main switch?
The EPH-S11104 is an RCCB incomer consumer unit, rather than a main switch-only model. Its factory-fitted RCCB provides manual switching and residual current protection. The manufacturer description does not identify a separate main switch-disconnector.
Does the ABB EPH-S11104 provide overload and short-circuit protection?
The 100 A RCCB provides residual current protection but does not independently protect against overloads or short circuits. Suitable upstream protection and correctly selected outgoing overcurrent protective devices are required for the completed electrical installation.
