Why Choose the ABB EPH-S11219-AF Protecta Home 19-Way Dual RCD AFDD-Compatible Consumer Unit?
The ABB EPH-S11219-AF (1TVC151800S3085) is a 19-way, 100 A main switch consumer unit featuring two 100 A residual current circuit breakers (RCCBs). Designed for residential and light commercial electrical distribution, this ABB Protecta Home consumer unit combines incoming supply isolation, dual RCD protection and generous modular capacity in a durable steel enclosure.
As part of ABB's Protecta Home AFDD-compatible split-load consumer unit range, the EPH-S11219-AF is designed to accommodate appropriately selected arc fault detection devices and other compatible modular circuit protection equipment. Its 19-way, 38-module configuration provides additional installation space for protective devices that may occupy more than one modular position.
The EPH-S11219-AF incorporates a 100 A main switch-disconnector and 2 × 100 A RCCBs, allowing outgoing circuits to be arranged into two residual current-protected groups. With nominal enclosure dimensions of 500 × 450 × 105 mm (H × W × D), this steel consumer unit provides a practical distribution solution for electrical installations requiring substantial circuit capacity and flexible protection arrangements.

High-Capacity AFDD-Compatible Distribution with Dual 100A RCCB Protection
The ABB EPH-S11219-AF is designed for electrical installations requiring a larger number of outgoing circuits and sufficient modular space for modern protective devices. Its 19-way, 38-module layout makes it particularly suitable for arrangements incorporating compatible arc fault detection devices, which may require more enclosure space than conventional single-module miniature circuit breakers.
The 100 A main switch-disconnector provides a central point of manual supply isolation, while the two 100 A RCCBs provide residual current protection for their respective circuit groups. ABB's variable split-load design allows the allocation of outgoing ways between these groups to be configured within the manufacturer's approved assembly arrangements. The completed circuit design should consider expected loading, cumulative protective conductor currents, circuit continuity and the consequences of an RCCB operating.
Arc fault detection devices (AFDDs) are designed to identify certain potentially hazardous electrical arcing conditions. The EPH-S11219-AF is an AFDD-compatible enclosure configuration; it should not be assumed that outgoing AFDDs are included with the consumer unit. Appropriate devices must be selected separately according to the installation requirements and ABB's compatibility information.
The 100 A rating of each RCCB identifies its rated current, not its residual operating current. RCCBs do not independently provide overload or short-circuit protection, so suitable upstream and outgoing overcurrent protection must be incorporated into the installation. The consumer unit must be installed and verified in accordance with BS 7671, the manufacturer's instructions and applicable electrical safety requirements.
Typical Applications
- Residential electrical distribution installations requiring multiple outgoing circuits.
- New-build houses and residential development projects.
- Domestic consumer unit replacements and electrical upgrades.
- Properties requiring AFDD-compatible circuit protection arrangements.
- Electrical installations incorporating suitable arc fault detection devices.
- Split-load distribution systems with two RCCB-protected circuit groups.
- Large domestic electrical installations with numerous lighting and socket circuits.
- Residential extensions and major refurbishment projects.
- Light commercial premises and small offices.
- Workshops, garages and ancillary building electrical distribution.
- Professional indoor electrical installations requiring a 19-way, 38-module consumer unit.
