Why Choose the ABB EPH-S66320 Protecta Home 20-Way Consumer Unit?

The ABB EPH-S66320 is a robust and reliable 20-way triple split-load consumer unit designed for safe and organised electrical distribution in residential installations. As part of the established ABB Protecta Home consumer unit series, it features a 63 A main switch isolator and three 63 A residual current circuit breakers (RCCBs), providing central supply isolation and residual current protection across three separate groups of outgoing circuits.

This consumer unit combines a durable steel enclosure with a practical triple split-load configuration, allowing electrical circuits to be distributed between three RCCB-protected sections. The arrangement supports flexible circuit allocation and helps organise electrical protection throughout the installation. Its robust construction and accessible design make it suitable for installation, inspection and maintenance by qualified electrical professionals.

With 20 outgoing ways, a 63 A main isolator and three 63 A RCCBs, the EPH-S66320 is ideal for domestic electrical installations requiring multiple protected circuits. The consumer unit features nominal enclosure dimensions of 500 mm high × 330 mm wide × 105 mm deep, providing a practical distribution solution for residential properties with extensive electrical circuit requirements.

Key Advantages

  • Robust 20-way consumer unit designed for residential electrical distribution.
  • 63 A main switch isolator provides convenient isolation of the incoming electrical supply.
  • Three 63 A RCCBs provide residual current protection across separate circuit groups.
  • Triple split-load configuration enables flexible distribution of outgoing electrical circuits.
  • Variable split arrangement supports circuit allocation according to installation requirements.
  • Durable steel enclosure provides mechanical protection for internal electrical components.
  • 20 outgoing ways accommodate multiple residential circuits.
  • Compatible with appropriately selected ABB modular circuit protection devices.
  • Practical enclosure dimensions of 500 × 330 × 105 mm.
  • Part of the established ABB Protecta Home range for domestic electrical installations.

Key Features

  • ABB Protecta Home consumer unit series.
  • 20-way outgoing circuit configuration.
  • 63 A rated main switch isolator.
  • 3 × 63 A residual current circuit breakers (RCCBs).
  • Triple split-load arrangement with three RCCB-protected circuit groups.
  • Variable split configuration for flexible circuit distribution.
  • Robust steel enclosure construction.
  • Designed for domestic low-voltage electrical distribution.
  • Supports installation of compatible miniature circuit breakers.
  • Organised circuit distribution for lighting, socket outlets and fixed electrical equipment.
  • 500 mm nominal enclosure height.
  • 330 mm nominal enclosure width.
  • 105 mm nominal enclosure depth.

Reliable Electrical Distribution and Circuit Protection

Consumer units such as the ABB EPH-S66320 provide a central location for electrical isolation, power distribution and circuit protection within residential installations. The integrated 63 A main switch isolator allows the incoming supply to be disconnected when required, while the three 63 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 risk of electric shock and electrical hazards.

The ABB Protecta Home series is designed to support practical electrical distribution and organised circuit protection. The EPH-S66320 incorporates a triple split-load configuration, allowing outgoing circuits to be arranged between three RCCB-protected sections. This provides greater flexibility when grouping circuits and can limit the number of circuits affected by an individual RCCB operation compared with arrangements using fewer shared RCCBs. Individual outgoing circuits must be fitted with suitably rated overcurrent protective devices, and the installation must be designed in accordance with applicable wiring regulations.

Typical Applications

  • Residential electrical distribution in houses and domestic properties.
  • New-build housing electrical installations.
  • Consumer unit replacement and electrical refurbishment projects.
  • Domestic installations requiring 20 outgoing circuit ways.
  • Triple split-load distribution systems with three RCCB-protected groups.
  • Lighting and socket-outlet circuit distribution.
  • Electrical distribution for domestic appliances and fixed equipment.
  • Residential properties with multiple electrical circuit requirements.
  • Domestic installations requiring central supply isolation and residual current protection.
  • Electrical installation projects requiring flexible circuit grouping.
