1TVC151800S3098 ABB EPH-S11102 Protecta Home 2 Way 100A RCCB Consumer Unit

Why Choose the ABB EPH-S11102 Protecta Home 2-Way 100A RCCB Consumer Unit?

The ABB EPH-S11102 (1TVC151800S3098) is a compact 2-way, 100 A RCCB consumer unit from the ABB Protecta Home range, designed for residential and light commercial electrical distribution. Featuring a factory-fitted residual current circuit breaker (RCCB) as the incoming device, this consumer unit provides residual current protection for compatible outgoing circuits within a durable steel enclosure.

Unlike a conventional main switch-only consumer unit, the ABB EPH-S11102 incorporates a 100 A RCCB incomer, combining manual switching with residual current protection. This arrangement makes it a practical choice for smaller electrical distribution installations where a limited number of outgoing circuits require a common residual current protective device.

ABB's Protecta Home selection information confirms a 2-way, 2-module configuration with nominal enclosure dimensions of 250 × 190 × 105 mm (H × W × D). The unit features a RAL 7035 grey steel enclosure and is supplied with a shrouded busbar, earth and neutral terminal bars, and installation instructions, providing a convenient starting point for professional electrical installations.

Understanding the 100A RCCB Incomer and Two-Way Circuit Arrangement

The ABB EPH-S11102 belongs to the 100 A RCCB incomer section of the Protecta Home consumer unit range. Its factory-fitted RCCB monitors the balance of current flowing through the conductors it protects and disconnects the supply when residual current exceeds the device's specified operating threshold. This functionality is particularly important in electrical installations where residual current protection is required.

The 100 A rating describes the RCCB's rated current, not its residual operating current. The residual operating current, RCCB type and other protective characteristics must be confirmed from the actual fitted device before installation. A 100 A RCCB must not be assumed to provide overload or short-circuit protection: appropriate upstream protection and correctly selected outgoing overcurrent protective devices remain necessary.

With two outgoing ways, the EPH-S11102 is suited to small circuit groups and dedicated distribution requirements. The supplied shrouded busbar, neutral bar and earth bar help installers arrange compatible protective devices and conductors neatly within the enclosure. The final circuit configuration must follow ABB's compatibility and assembly instructions.

The Protecta Home steel consumer unit range is designed to BS EN 61439-3, covering low-voltage distribution boards intended to be operated by ordinary persons. Electrical installations must also comply with applicable requirements of BS 7671. The RCCB incomer provides common residual current protection, meaning an RCCB trip can disconnect all outgoing circuits supplied through it; circuit selection should therefore consider continuity of supply and the requirements of the installation.

Typical Applications

• Small residential electrical distribution installations.
• Dedicated electrical circuit groups requiring a common RCCB incomer.
• Domestic electrical refurbishment and upgrade projects.
• Garages and workshops with limited outgoing circuit requirements.
• Utility areas and ancillary building electrical distribution.
• Small indoor electrical installations using compatible modular protective devices.
• Light commercial distribution applications requiring a compact consumer unit.
• Replacement of suitable existing RCCB incomer consumer units.
• Electrical distribution installations requiring two outgoing ways and a 100 A RCCB incomer.
