Why Choose the ABB EPH-S11215-AF Protecta Home 15-Way Dual RCD Consumer Unit?
The ABB EPH-S11215-AF (1TVC151800S3084) is a 15-way, 100 A main switch consumer unit with two 100 A residual current circuit breakers (RCCBs), designed for residential and light commercial electrical distribution. Part of the ABB Protecta Home range, this consumer unit features an AFDD-compatible split-load arrangement that supports modern circuit protection requirements.
Featuring a 100 A main switch-disconnector and 2 × 100 A RCCBs, the EPH-S11215-AF combines centralised electrical isolation with residual current protection for separately configured circuit groups. Its 15-way AFDD split-load design provides additional modular space to accommodate compatible arc fault detection devices (AFDDs) and other approved outgoing protective equipment.
ABB's Protecta Home selection guide identifies this model as a 15-way, 30-module steel consumer unit with nominal dimensions of 500 × 380 × 105 mm (H × W × D). This configuration provides a practical solution for installations requiring multiple outgoing circuits, dual RCCB protection and the additional modular space associated with AFDD installations.

AFDD-Ready Distribution with Dual 100A RCCB Protection
The ABB EPH-S11215-AF is designed for installations where both residual current protection and accommodation for arc fault detection devices are important considerations. Its 100 A main switch provides a central point of supply isolation, while the two 100 A RCCBs provide residual current protection for separately configured outgoing circuit groups.
The 15-way, 30-module arrangement is particularly relevant to AFDD installations because compatible AFDD protective devices can require more modular space than conventional single-module MCBs. The EPH-S11215-AF provides an enclosure layout specifically identified by ABB for AFDD split-load applications. AFDD compatibility does not mean that AFDD devices are factory-fitted; the required outgoing protective devices must be selected according to the installation design and confirmed supply configuration.
ABB identifies Protecta Home RCCB split-load consumer units as having a variable split arrangement. This supports the allocation of outgoing circuits between the RCCB groups, subject to the manufacturer's approved assembly configuration. The 100 A RCCB rating represents the rated current of each device and is not its residual operating current. RCCBs do not independently provide overload or short-circuit protection, so suitable overcurrent protection remains essential. Installation must comply with the applicable requirements of BS 7671 and ABB's instructions.
Typical Applications
- Residential consumer unit installations requiring AFDD-compatible circuit arrangements.
- New-build housing developments.
- Domestic electrical distribution board replacements and upgrades.
- Residential installations with multiple outgoing circuits.
- Split-load electrical distribution requiring two RCCB-protected circuit groups.
- Electrical installations incorporating compatible arc fault detection devices.
- Lighting and socket outlet circuits with appropriately selected protection.
- Property renovation and electrical refurbishment projects.
- Light commercial premises and small offices.
- Professional electrical distribution installations requiring a 15-way, 30-module consumer unit.
