Why Choose the ABB EPH-S16212 Protecta Home 12-Way 100A Dual RCD Consumer Unit?
The ABB EPH-S16212 (1TVC151800S3067) is a 12-way, 100 A main switch consumer unit with two 63 A RCCBs, designed for residential and light commercial electrical distribution. Part of the ABB Protecta Home range, this dual RCD consumer unit provides a practical solution for organising outgoing electrical circuits into separately protected groups within a robust steel enclosure.
Featuring a 100 A main switch-disconnector and two 63 A residual current circuit breakers (RCCBs), the EPH-S16212 combines centralised supply isolation with residual current protection for appropriately configured circuit groups. Its split-load arrangement allows outgoing circuits to be distributed between the two RCCBs, helping installers create an organised electrical installation suited to the building's protection requirements.
With 12 outgoing ways and manufacturer-listed nominal dimensions of 250 × 380 × 105 mm (H × W × D), the ABB EPH-S16212 provides a compact yet versatile distribution solution. The Protecta Home steel enclosure is suitable for professional consumer unit installations where dependable construction, convenient access and flexible circuit arrangements are essential.

Flexible Dual RCD Protection for Split-Load Electrical Installations
The ABB EPH-S16212 is designed around a 100 A main switch and two 63 A RCCBs. The main switch provides a central point of isolation for the consumer unit, while the RCCBs provide residual current protection for their respective outgoing circuit groups. This arrangement allows circuits to be divided between two protective devices rather than placing all outgoing circuits under a single RCCB.
A key advantage of the EPH-S16212 is its variable split-load arrangement. ABB identifies the RCCB split configuration as adjustable within the relevant Protecta Home consumer unit range, allowing installers to allocate outgoing ways according to the installation design and compatible assembly components. Circuit allocation should take account of expected loads, leakage currents, protective device coordination and the consequences of an RCCB operating.
The 63 A rating of each RCCB refers to its rated current and must not be confused with the residual operating current used for earth leakage protection. RCCBs do not provide overload or short-circuit protection by themselves, so correctly selected overcurrent protective devices and appropriate upstream protection remain essential. The completed installation must meet the applicable requirements of BS 7671 and the manufacturer's assembly instructions.
