Why Choose the ABB EPH-S66219-AF Protecta Home 19-Way Consumer Unit?
The ABB EPH-S66219-AF is a robust and versatile 19-way split-load consumer unit designed for MCB and Arc Fault Detection Device (AFDD) installations in domestic and residential electrical distribution systems. As part of the established ABB Protecta Home series, this consumer unit incorporates a 63 A main switch isolator and two 63 A residual current circuit breakers (RCCBs), providing a practical arrangement for circuit isolation and residual current protection.
Designed to accommodate modern electrical protection requirements, the EPH-S66219-AF provides space for suitable miniature circuit breakers (MCBs) and arc fault detection devices, allowing electricians to configure outgoing circuits according to installation requirements. Its split-load configuration separates circuits into RCCB-protected groups, while its AFDD-compatible layout supports the use of additional arc fault protection where required.
With 19 outgoing ways, a 63 A main isolator and two 63 A RCCBs, the EPH-S66219-AF is suitable for residential installations requiring organised electrical distribution and flexible protective device selection. Its 38-module capacity and nominal dimensions of 500 × 450 × 105 mm (H × W × D) provide the additional installation space required for MCB and AFDD arrangements within a durable steel enclosure.

Reliable Electrical Distribution with AFDD-Compatible Circuit Protection
Modern domestic electrical installations require effective circuit protection, reliable isolation and sufficient space for protective devices. The ABB EPH-S66219-AF Protecta Home consumer unit provides a practical distribution solution by combining a 63 A main switch isolator with two 63 A RCCBs and an enclosure arrangement designed to accommodate suitable MCBs and AFDDs.
The two RCCBs provide residual current protection for their respective groups of outgoing circuits. These devices monitor the balance between live and neutral currents and disconnect the protected circuits when a residual current fault exceeds the device's operating threshold. This helps reduce the risk of electric shock and certain electrical fault hazards when the installation is correctly designed and maintained. RCCBs do not provide overload or short-circuit protection independently, so suitable overcurrent protective devices must be installed.
The AFDD-compatible design allows electricians to incorporate appropriate arc fault detection devices into the distribution system. AFDDs are designed to detect characteristic electrical arcing faults that may not be identified by conventional overcurrent or residual current protective devices. When correctly selected and installed, they provide an additional level of protection against electrical fire risks associated with dangerous arcing conditions. The EPH-S66219-AF is designed to accommodate AFDDs; individual AFDD devices must be selected separately according to the circuit requirements.
The 38-module enclosure capacity provides the space required for wider protective devices, while the robust steel construction, shrouded busbar and integrated terminal bars support organised installation and maintenance. As part of the ABB Protecta Home range, this consumer unit offers a dependable platform for residential electrical distribution systems requiring flexible circuit protection arrangements.
