1TVC151800S3075 ABB EPH-S11320 Protecta Home 20-Way 100A Consumer Unit with 3 x 100A RCCBs

Why Choose the ABB EPH-S11320 Protecta Home 20-Way Consumer Unit?

The ABB EPH-S11320 is a robust and versatile 20-way, 100 A consumer unit with a 100 A main switch and three 100 A residual current circuit breakers (RCCBs), designed for safe and organised electrical distribution in domestic and residential installations. Part of the trusted ABB Protecta Home consumer unit series, this steel-enclosed distribution board provides a practical solution for electricians and electrical contractors requiring reliable circuit isolation, residual current protection and flexible circuit arrangements.

Featuring a triple RCCB split-load configuration, the EPH-S11320 allows outgoing circuits to be distributed across three residual current protection groups. This arrangement supports effective circuit organisation and can help limit the number of circuits affected by an individual RCCB trip compared with a single-RCCB installation. The integrated main switch provides a convenient means of isolating the consumer unit for electrical maintenance and servicing.

With 20 outgoing ways, a 100 A main switch and three 100 A RCCBs, the EPH-S11320 is suitable for residential electrical installations requiring multiple protected circuit groups. Its durable steel enclosure and compact vertical design make it particularly suitable for wall-mounted electrical distribution applications. The unit measures approximately 500 × 330 × 105 mm (H × W × D), providing a practical balance between circuit capacity and installation space.

Reliable Electrical Protection and Distribution for Residential Installations

Consumer units such as the ABB EPH-S11320 Protecta Home provide a central location for distributing electrical power to individual circuits throughout a property. The main switch enables isolation of the incoming supply to the distribution board, while the three RCCBs provide residual current protection for their respective circuit groups. When an RCCB detects an earth leakage imbalance exceeding its operating threshold, it disconnects the associated circuits to help reduce the risk of electric shock and electrical hazards.

The three-RCCB split-load arrangement offers additional flexibility when organising household electrical circuits. Installers can distribute compatible outgoing circuits across separate RCCB groups according to the electrical installation design. This can help reduce disruption by preventing a fault affecting one RCCB group from automatically disconnecting every circuit in the consumer unit. RCCBs do not provide overload or short-circuit protection, so appropriately rated MCBs or other compatible protective devices are required for the outgoing circuits.

The Protecta Home range is developed for residential distribution applications where reliable switching, circuit organisation and practical installation are important. The EPH-S11320 combines a robust steel enclosure with a substantial 20-way capacity, making it suitable for properties requiring multiple electrical circuits and organised residual current protection. Installation, circuit allocation and protective device selection must be carried out by a competent electrician in accordance with applicable electrical installation regulations.
