1SKT330844C0001 ABB EPP-S844 Protecta Plus 8+4+4-Way 250 A Distribution Board

Why Choose the ABB EPP-S844 Protecta Plus 8+4+4-Way 250 A Distribution Board?

The ABB EPP-S844, order code 1SKT330844C0001, is a 250 A Protecta Plus vertical split-load distribution board designed for commercial and industrial power-distribution applications. Its 8+4+4-way configuration divides the outgoing circuits into three sections, providing a practical platform for separating different loads, services or circuit groups within one enclosure.

The Protecta Plus platform uses 250 A main busbars and is designed for indoor wall-mounted installation. The EPP-S844 enclosure is manufactured from 1 mm sheet steel with an epoxy-coated, textured RAL 7035 light-grey finish, combining robust construction with straightforward access for wiring and maintenance.

Measuring approximately 1380 × 450 × 130 mm, the EPP-S844 provides a substantial yet organised distribution solution for installations requiring multiple separately arranged outgoing sections. Protecta Plus assemblies provide IP43 protection with the door fitted, IK07 mechanical impact resistance and a rated conditional short-circuit current of 35 kA.

Flexible Split-Load Power Distribution

The ABB Protecta Plus system is designed to give installers flexibility when configuring sub-distribution equipment for commercial and industrial buildings. The EPP-S844's 8+4+4 arrangement divides its outgoing capacity into three distinct sections, helping designers organise different circuit groups while retaining them within one coordinated distribution-board enclosure.

The 250 A busbar system, robust steel enclosure and 35 kA conditional short-circuit rating provide a dependable foundation for power distribution. Protecta Plus also supports a broad selection of ABB modular protection, metering, monitoring and surge-protection equipment, allowing the completed assembly to be configured for the requirements of the installation.

Typical Applications

• Commercial three-phase power distribution.
• Industrial sub-distribution systems.
• Lighting, power and services distribution.
• Office and retail developments.
• Factories and manufacturing facilities.
• Plant rooms and building-services installations.
• Applications requiring separately organised outgoing circuit groups.
• ABB Protecta Plus distribution systems.
