1TVC151800S3078 ABB EPH-11244-AM Protecta Home 4+4-Way Consumer Unit 100A Main Switch 2x100A RCCB MCB/AFDD

Why Choose the ABB EPH-11244-AM Protecta Home 4+4-Way Consumer Unit?

The ABB EPH-11244-AM is a compact and reliable 4+4-way split-load consumer unit with a 100 A main switch isolator and two 100 A residual current circuit breakers (RCCBs), designed for safe and organised electrical distribution in residential installations. As part of the established ABB Protecta Home consumer unit series, it features a specialised split MCB/AFDD arrangement that supports the installation of compatible miniature circuit breakers and arc fault detection devices.

This consumer unit combines a durable steel enclosure with a practical dual RCCB split-load configuration, allowing outgoing circuits to be organised into two separately protected groups. The arrangement provides flexibility for domestic electrical installations while supporting the use of compatible arc fault detection devices (AFDDs), which can help reduce fire risks associated with dangerous electrical arcing faults when correctly selected and installed.

With a 4+4-way configuration providing 8 outgoing ways, a 100 A main isolator and two 100 A RCCBs, the EPH-11244-AM is suitable for residential distribution systems requiring flexible circuit protection. The consumer unit provides 12 modular spaces and has nominal enclosure dimensions of 250 mm high × 380 mm wide × 105 mm deep, making it a practical solution for domestic electrical installations.

Reliable Electrical Distribution and Advanced Circuit Protection

Consumer units such as the ABB EPH-11244-AM provide a central location for electrical isolation, circuit distribution and protective devices in residential installations. The integrated 100 A main switch isolator allows the incoming electrical supply to be disconnected when required, while the two 100 A RCCBs monitor residual current within their respective circuit groups. When an RCCB detects a residual current fault exceeding its operating threshold, it disconnects the associated circuits to help reduce the risks associated with earth leakage faults.

The ABB Protecta Home series supports modern domestic electrical distribution requirements through practical enclosure designs and flexible protective device arrangements. The EPH-11244-AM features a split MCB/AFDD configuration, allowing appropriately selected miniature circuit breakers and arc fault detection devices to be incorporated into the installation. Compatible AFDDs provide additional protection by detecting certain hazardous electrical arcing conditions that conventional overcurrent and residual current protective devices may not identify.

The 4+4-way split-load arrangement enables installers to organise outgoing circuits across two RCCB-protected groups. Individual circuits require appropriately rated overcurrent protection, and the selection of MCBs, AFDDs and other protective devices must account for circuit characteristics, installation requirements and applicable wiring regulations. The 100 A main switch and RCCB ratings represent the ratings of those components and do not remove the need for suitable upstream protection and circuit load assessment.
