Why Choose the ABB EPH-S66102 Protecta Home 2-Way 63A RCCB Consumer Unit?
The ABB EPH-S66102 (1TVS151800S3050) is a compact 2-way, 63 A RCCB incomer consumer unit from the ABB Protecta Home range. Designed for residential and suitable light commercial electrical distribution applications, it provides a practical enclosure for a small number of outgoing circuits requiring common residual current protection.
Featuring a factory-fitted 63 A residual current circuit breaker (RCCB), the ABB EPH-S66102 combines manual switching and residual current protection within a single incoming device. The two-way configuration is particularly useful for smaller distribution requirements, dedicated circuit groups, garages, outbuildings and appropriately designed electrical refurbishment projects.
ABB's Protecta Home selection guide identifies the EPH-S66102 as a 2-way, 2-module steel consumer unit with nominal dimensions of 250 × 190 × 105 mm (H × W × D). The enclosure is finished in RAL 7035 grey and belongs to ABB's steel consumer unit range designed to BS EN 61439-3. It is supplied with a shrouded busbar, earth and neutral terminal bars, and installation instructions, providing a convenient foundation for professional electrical distribution installations.

Understanding the 63A RCCB Incomer and Two-Way Circuit Configuration
The ABB EPH-S66102 belongs to the 63 A RCCB incomer section of the Protecta Home consumer unit range. Its incoming RCCB detects residual current imbalance between the conductors passing through the device and disconnects the supply when the residual current exceeds its specified operating threshold. This provides an important protective function for appropriately designed electrical installations.
The 63 A rating refers to the RCCB's rated current and should not be confused with its residual operating current, commonly expressed in milliamperes. The precise residual operating current and RCCB type must be confirmed from the fitted device before installation. An RCCB does not independently provide overload or short-circuit protection, so suitable upstream protection and correctly selected outgoing overcurrent protective devices remain essential.
The two outgoing ways make the EPH-S66102 suitable for small distribution arrangements where a common RCCB incomer is appropriate. The included shrouded busbar, neutral terminal bar and protective earth terminal bar help installers organise compatible modular devices and electrical connections within the enclosure.
Because the outgoing circuits share one RCCB incomer, operation of the RCCB can disconnect all circuits supplied through it. Electrical designers should consider continuity of supply, protective conductor currents and the installation's earthing arrangement when selecting this configuration. Installation and verification must follow BS 7671 and ABB's assembly instructions.
