1TVC151800S3076 ABB EPH-S66316 Protecta Home 16-Way 63A Consumer Unit with 3 x 63A RCCBs

Why Choose the ABB EPH-S66316 Protecta Home 16-Way Consumer Unit?

The ABB EPH-S66316 is a reliable and versatile 16-way, 63 A triple split-load consumer unit designed for safe and organised electrical distribution in domestic and residential installations. Featuring a 63 A main switch and three 63 A residual current circuit breakers (RCCBs), this consumer unit provides convenient supply isolation and residual current protection across three separate circuit groups. As part of the established ABB Protecta Home series, it is designed for electricians and electrical contractors seeking dependable circuit distribution and flexible installation options.

The EPH-S66316 features a triple RCCB split-load arrangement, allowing outgoing electrical circuits to be distributed between three residual current protection groups. This configuration helps improve circuit organisation and can reduce disruption caused by an individual RCCB trip compared with installations using a single RCCB. The integrated main switch provides a central means of isolating the consumer unit for maintenance and electrical installation work.

With 16 outgoing ways, a 63 A main switch and three 63 A RCCBs, the EPH-S66316 offers a practical solution for residential properties requiring multiple protected circuits. Its robust steel enclosure and compact wall-mounted format make it suitable for fixed electrical installations where space and accessibility are important. Measuring 250 × 490 × 105 mm (H × W × D), the consumer unit provides substantial circuit capacity within a convenient horizontal enclosure.

Reliable Electrical Protection for Domestic Distribution Systems

Consumer units such as the ABB EPH-S66316 Protecta Home provide a central distribution point for electrical circuits within residential properties. The integrated 63 A main switch enables isolation of the consumer unit, while the three 63 A RCCBs provide residual current protection for their respective outgoing circuit groups. RCCBs detect imbalances between the live and neutral currents and disconnect the associated circuits when residual current exceeds their operating threshold, helping reduce the risk of electric shock and electrical hazards.

The triple split-load design allows electricians to organise electrical circuits across three independently protected groups. This can be particularly beneficial in properties with multiple lighting, socket outlet and appliance circuits. By separating circuits between RCCBs, an earth leakage fault affecting one group does not automatically disconnect the other two groups. Appropriate circuit allocation is important for maintaining electrical safety and reducing unnecessary disruption.

The EPH-S66316 forms part of the ABB Protecta Home steel consumer unit range, developed for dependable residential electrical distribution. Its adaptable split-load arrangement and 16-way capacity provide flexibility for different installation requirements. RCCBs provide residual current protection but do not replace the need for correctly rated overload and short-circuit protective devices. Installation must be completed by a competent electrician using compatible protective devices and in accordance with applicable electrical installation regulations, including BS 7671.

Typical Applications

• Domestic electrical distribution in houses and residential properties.
• New-build housing and residential electrical installations.
• Consumer unit replacement and electrical distribution upgrades.
• Lighting and socket outlet circuit distribution.
• Kitchen, utility room and household appliance circuits.
• Residential installations requiring three separate RCCB protection groups.
• Electrical refurbishment and property rewiring projects.
• Small residential buildings requiring a 16-way consumer unit.
• Fixed electrical installations with a suitably rated 63 A incoming arrangement.
• Wall-mounted electrical distribution and circuit protection systems.
