1TVC151800S3062 ABB EPH-S66208 Protecta Home 8-Way 63A Main Switch Dual 63A RCCB Split-Load Consumer Unit

Why Choose the ABB EPH-S66208 8-Way Protecta Home Split-Load Consumer Unit?

The ABB EPH-S66208 Protecta Home Consumer Unit (1TVC151800S3062) is a genuine ABB 8-way split-load consumer unit featuring a 63 A main switch isolator and two 63 A residual current circuit breakers (RCCBs). Designed for professional electrical distribution installations, it provides a compact, coordinated assembly for accommodating compatible outgoing circuit protection devices.

Part of the ABB Protecta Home range, the EPH-S66208 features a durable steel enclosure finished in RAL 7035 light grey. Its adaptable split-load arrangement enables suitable outgoing circuits to be divided between two RCCB-protected sections, subject to the installation design and ABB's assembly instructions.

With nominal dimensions of 250 mm high, 330 mm wide and 105 mm deep, this consumer unit offers a practical solution where installation space is limited. The assembly is supplied with factory-fitted incoming devices, a shrouded busbar, neutral and earth bars, and installation instructions, and is designed to BS EN 61439-3.

Dual 63 A RCCB Split-Load Protection

The ABB EPH-S66208 combines a 63 A incoming main switch with two 63 A RCCBs, allowing outgoing circuits to be organised into two residual current protection groups.

This arrangement can be useful in domestic electrical installations where circuits are divided between separate RCCB sections. If one RCCB trips, the circuits connected to that section may lose supply while circuits on the other section can remain energised, provided no wider supply interruption has occurred.

ABB identifies its RCCB split-load consumer units as having a variable split arrangement. The actual distribution of outgoing ways must be configured using the approved busbar and terminal arrangement and in accordance with the manufacturer's instructions.

The two 63 A RCCBs do not provide a combined incoming current rating of 126 A. The assembly has a 63 A main switch, and the complete installation must be designed within the applicable equipment and supply ratings.

Compact Steel Enclosure for Residential Distribution

With nominal dimensions of 250 x 330 x 105 mm, the ABB EPH-S66208 is one of the more compact dual-RCCB configurations in the Protecta Home range. Its eight-way layout makes it suitable for installations requiring a modest number of outgoing circuits while retaining a split-load arrangement.

The RAL 7035 steel enclosure provides a coordinated housing for the factory-fitted switching equipment, residual current devices and compatible outgoing circuit breakers.

Before installation, the electrician should verify the available mounting space, cable entry arrangement, accessibility and any required working clearances. The published dimensions are nominal enclosure dimensions and should not be treated as wall cut-out measurements.

Factory-Fitted Main Switch, RCCBs and Terminal Equipment

The EPH-S66208 is supplied with the incoming 63 A switch disconnector and two 63 A RCCBs already fitted. ABB also specifies a shrouded busbar, neutral and earth bars, and installation instructions as part of the Protecta Home steel consumer unit assembly.

These components provide a coordinated foundation for the completed electrical distribution board. The neutral terminal arrangement must correspond to the two RCCB-protected circuit groups, while protective earth connections must maintain the required continuity.

Outgoing miniature circuit breakers are not identified as included in the standard EPH-S66208 configuration. They should be selected separately using the approved ABB device range and the requirements of each outgoing circuit.

Installation, Circuit Design and Electrical Safety

The ABB EPH-S66208 should be installed by a competent electrical professional in accordance with the applicable wiring regulations, including BS 7671 where relevant, and ABB's product-specific instructions.

Each RCCB-protected circuit must have its line and neutral conductors arranged correctly. Neutrals from different RCCB groups must not be mixed, as incorrect connections can lead to unwanted tripping or improper operation.

RCCBs provide residual current protection but do not independently provide the overload and short-circuit protection required for outgoing circuits. Suitable circuit breakers or other approved protective devices must therefore be selected and installed as part of the completed assembly.

The specified 63 A RCCB rating refers to rated current, not residual-current sensitivity. The required RCCB type and residual operating current must be checked against the actual fitted devices and installation requirements.
