Why Choose the ABB EPH-S66110 Protecta Home 10-Way 63 A RCCB Consumer Unit?
The ABB EPH-S66110 is a 10-way, 63 A RCCB-controlled consumer unit from the ABB Protecta Home range, designed for residential and light commercial electrical distribution. Featuring a 63 A residual current circuit breaker (RCCB) as its incoming protective device, this consumer unit combines residual current protection with a practical arrangement for distributing power to multiple outgoing circuits.
Designed to accommodate 10 outgoing circuit ways, the EPH-S66110 provides a convenient solution for installations requiring a single RCCB-protected circuit group. Its incoming RCCB monitors residual current imbalance and disconnects the associated circuits when its specified operating conditions are met, helping support electrical safety as part of a correctly designed installation.
Housed in a durable steel enclosure measuring 250 × 290 × 105 mm, the ABB EPH-S66110 combines compact dimensions with organised electrical distribution. The Protecta Home assembly is supplied with its specified incoming RCCB, shrouded busbar, earth and neutral bars, and installation instructions, providing a practical foundation for professional consumer unit installation.

Practical 10-Way Electrical Distribution with 63 A RCCB Protection
The ABB EPH-S66110 is designed for electrical installations requiring a compact consumer unit with a single incoming residual current protective device. Its 10-way configuration provides space for compatible miniature circuit breakers and other approved modular protective devices, allowing electricians to organise outgoing circuits according to the electrical installation design.
The consumer unit incorporates a 63 A RCCB as its incoming protective device. Unlike a main switch-only consumer unit, this arrangement provides residual current protection for the outgoing circuits connected through the RCCB. The device monitors the balance between outgoing and returning current and disconnects the protected circuits when a qualifying residual current imbalance occurs.
The 63 A rating describes the current-carrying capacity of the RCCB and must not be confused with its residual current operating sensitivity. The actual residual current sensitivity, RCCB type and operating characteristics must be confirmed from the installed protective device specification.
Because the EPH-S66110 uses a single RCCB-controlled arrangement, a residual current fault on one outgoing circuit may cause the incoming RCCB to disconnect all circuits supplied through it. This shared protection arrangement should be considered when assessing circuit grouping, continuity of supply and the suitability of the consumer unit for a particular installation.
Importantly, an RCCB does not independently provide overload or short-circuit protection. Appropriate miniature circuit breakers or other compatible overcurrent protective devices must therefore be selected for the outgoing circuits. Suitable upstream overcurrent protection must also be provided for the RCCB in accordance with the installation design and ABB instructions.
The incoming RCCB may provide switching and isolation functionality where the installed device is approved and suitable for that purpose. However, the EPH-S66110 is an RCCB-controlled consumer unit rather than a separate 63 A main switch plus RCCB configuration. This distinction is important when comparing ABB Protecta Home models.
The steel enclosure provides robust housing for the electrical distribution assembly. Its nominal dimensions of 250 × 290 × 105 mm, RAL 7035 finish, shrouded busbar and conductor termination bars help provide an organised platform for professional installation.
Final protective device selection, conductor sizing, earthing arrangements, circuit coordination and installation methods must comply with ABB instructions and applicable electrical installation regulations, including relevant BS 7671 requirements.
