Why Choose the ABB EPH-S11316 Protecta Home 16-Way Consumer Unit?
The ABB EPH-S11316 is a 16-way, 100 A triple-RCCB consumer unit from the ABB Protecta Home range, designed for residential and light commercial electrical distribution installations. Featuring a 100 A main switch isolator and three 100 A residual current circuit breakers (RCCBs), this consumer unit provides central supply isolation and three separately protected residual current circuit groups.
The EPH-S11316 combines 16 outgoing circuit ways with a triple-RCCB split-load arrangement, allowing electricians to organise compatible miniature circuit breakers across three residual current protection groups. This configuration offers additional flexibility when distributing lighting, socket outlet and fixed appliance circuits, helping reduce the number of circuits affected by a single RCCB operation compared with a single-RCCB arrangement.
Housed in a durable steel enclosure measuring 250 × 490 × 105 mm, the ABB EPH-S11316 provides a practical solution for installations requiring multiple outgoing circuits and three RCCB-protected sections. Its compact single-row design, 100 A main switch and three 100 A RCCBs make it suitable for professionally designed electrical distribution systems using compatible ABB circuit protection equipment.

Flexible 16-Way Distribution with Three 100 A RCCBs
The ABB EPH-S11316 is designed for electrical installations requiring multiple outgoing circuits and enhanced flexibility in residual current protection grouping. Its 16-way configuration provides space for compatible modular protective devices, allowing electricians to arrange lighting, socket outlets, fixed appliances and other circuits according to the electrical installation design.
The consumer unit incorporates a 100 A main switch isolator, providing a central means of disconnecting the incoming supply. Downstream of the main switch, three 100 A RCCBs establish separate residual current protection groups, enabling outgoing circuits to be distributed across three sections rather than relying on one or two shared RCCBs.
This triple-RCCB configuration can improve the organisation of outgoing circuits and help limit the extent of supply interruption caused by an individual RCCB trip. However, circuits sharing the same RCCB may still be disconnected together if a residual current fault occurs on one of those circuits.
Each RCCB monitors the residual current balance of its associated circuit group and disconnects that group when the device's specified operating conditions are met. The 100 A rating identifies the current-carrying capacity of each RCCB and must not be confused with its residual current operating sensitivity, which should be confirmed from the installed device specification.
Importantly, RCCBs do not independently provide overload or short-circuit protection. Compatible miniature circuit breakers or other suitable overcurrent protective devices must therefore be selected for outgoing circuits. The three 100 A RCCB ratings also do not imply that the consumer unit can supply a combined load of 300 A; the overall assembly remains subject to its incoming supply, main switch and manufacturer-specified operating limits.
The steel enclosure provides a robust housing for the distribution assembly, while its nominal dimensions of 250 × 490 × 105 mm support practical installation planning. Final circuit allocation, conductor sizing, protective device coordination and installation methods must follow ABB instructions and applicable electrical installation regulations.
