Why Choose the ABB EPH-S66216 Protecta Home 16-Way Consumer Unit?
The ABB EPH-S66216 is a 16-way, 63 A split-load consumer unit from the ABB Protecta Home range, designed for residential and light commercial electrical distribution installations. Featuring a 63 A main switch isolator and two 63 A residual current circuit breakers (RCCBs), this consumer unit provides a practical solution for distributing electrical circuits across two independently protected residual current groups.
The EPH-S66216 offers 16 outgoing circuit ways with an adaptable split-load arrangement, allowing electricians to organise compatible miniature circuit breakers and other approved protection devices according to installation requirements. Its two RCCBs provide residual current protection for their respective circuit groups, while the main switch enables central isolation of the consumer unit supply.
Housed in a durable steel enclosure with nominal dimensions of 250 × 450 × 105 mm, the ABB EPH-S66216 combines generous circuit capacity with a practical surface-mounted format. Supplied with factory-fitted switching and residual current protection equipment, a shrouded busbar, neutral and earth bars, and installation instructions, it provides a convenient platform for professional electrical distribution board assembly.

Flexible 16-Way Distribution with Dual 63 A RCCB Protection
The ABB EPH-S66216 is designed for electrical installations requiring a relatively high number of outgoing circuits within a single consumer unit. Its 16-way capacity allows electricians to configure separate circuits for lighting, socket outlets, kitchen appliances, heating systems and other electrical loads using appropriately selected modular protection devices.
The consumer unit incorporates a 63 A main switch isolator for central disconnection of the incoming supply. Two downstream 63 A RCCBs provide separate residual current protection groups, allowing outgoing circuits to be distributed between them rather than relying on one RCCB for the entire installation.
ABB's variable split-load arrangement offers flexibility in allocating outgoing ways between the two RCCB groups, subject to the approved busbar configuration and installation instructions. This enables the circuit layout to be planned around the requirements of the property and the electrical installation design.
Each RCCB monitors the residual current balance of its associated circuit group and disconnects that group when its specified residual current operating conditions are met. However, RCCBs do not provide independent overload or short-circuit protection. Compatible miniature circuit breakers or other suitable overcurrent protective devices must therefore be installed for outgoing circuits.
Dividing circuits between two RCCBs can reduce the number of circuits affected by a single residual current trip compared with an installation protected by one shared RCCB. Nevertheless, a fault on one circuit may still interrupt other circuits connected to the same RCCB. Circuit allocation should therefore consider continuity of supply, the nature of connected loads and applicable electrical installation regulations.
The steel enclosure provides a durable housing for the distribution assembly, while the RAL 7035 light grey finish offers a practical appearance for electrical cupboards, utility rooms and other suitable indoor locations. Factory-fitted switching equipment, a shrouded busbar and neutral and earth bars help simplify the assembly of a professionally installed consumer unit.
