Why Choose the ABB EPH-S11116 Protecta Home 16-Way Consumer Unit?
The ABB EPH-S11116 is a robust and reliable 16-way, 100 A RCCB incomer consumer unit designed for organised electrical distribution and residual current protection in domestic and residential installations. Featuring a factory-fitted 100 A residual current circuit breaker (RCCB), this consumer unit provides a central distribution point for multiple outgoing electrical circuits while incorporating earth leakage protection. As part of the established ABB Protecta Home consumer unit series, it offers electricians and electrical contractors a practical solution for residential installations requiring a single RCCB-controlled distribution arrangement.
The EPH-S11116 features a single RCCB incomer configuration, allowing compatible outgoing circuit protection devices to be installed downstream of the factory-fitted RCCB. This arrangement provides common residual current protection for the connected circuit group, while appropriately rated miniature circuit breakers (MCBs) can provide individual overload and short-circuit protection. The RCCB also provides switching and isolation of its downstream circuits when used in accordance with the manufacturer's instructions and appropriate safe isolation procedures.
With 16 outgoing ways and a 100 A rated RCCB incomer, the EPH-S11116 provides generous circuit capacity for domestic electrical distribution. Its durable RAL 7035 grey steel enclosure offers robust housing for electrical components, while its 250 × 380 × 105 mm (H × W × D) nominal dimensions support practical wall-mounted installation. The unit is supplied with a shrouded busbar, earth and neutral bars and installation instructions to assist with efficient installation and circuit organisation.

Reliable Residual Current Protection for Domestic Electrical Distribution
RCCB consumer units such as the ABB EPH-S11116 Protecta Home provide a central distribution point for electrical circuits while incorporating residual current protection. The factory-fitted 100 A RCCB monitors the balance of current flowing through the live and neutral conductors. If an earth leakage imbalance exceeds the device's specified operating threshold, the RCCB disconnects the associated circuits to help reduce the risk of electric shock and other electrical hazards.
The single RCCB incomer arrangement allows multiple outgoing circuits to share a common residual current protective device. This provides a straightforward distribution configuration where shared RCCB protection is appropriate for the electrical installation. However, because the outgoing circuits are connected through the same RCCB, an earth leakage fault affecting one circuit can disconnect all circuits supplied through that device. Circuit division, selectivity and continuity of supply requirements should therefore be considered during electrical installation design.
The ABB Protecta Home series combines durable steel enclosures with practical installation features for residential electrical distribution. The EPH-S11116 is supplied with a factory-fitted RCCB, shrouded busbar and earth and neutral bars, supporting organised installation of compatible outgoing protective devices. The RCCB provides residual current protection but does not itself provide overload or short-circuit protection. Appropriately rated overcurrent protective devices are therefore required, and installation must be carried out by a competent electrician in accordance with applicable electrical regulations, including BS 7671.
