Why Choose the ABB EPX-PB812 800A 12-Way Protecta Power Panelboard?
The ABB EPX-PB812 is a high-capacity 800 A 12-way moulded case circuit breaker (MCCB) distribution panelboard designed for reliable low-voltage electrical power distribution in commercial, industrial and infrastructure installations. As part of the ABB Protecta Power enclosure range, this panelboard provides a modular solution for distributing electrical power through multiple protected outgoing circuits while supporting straightforward installation, maintenance and future system modifications.
The EPX-PB812 incorporates an 800 A rated busbar system and provides 12 outgoing ways for compatible ABB Tmax XT moulded case circuit breakers. The Protecta Power system features innovative plug-in circuit breaker connections, an improved finger-safe busbar stack and modular enclosure accessories designed to simplify electrical distribution assembly and improve accessibility for authorised installation and maintenance personnel.
Measuring 1700 mm high × 1000 mm wide × 300 mm deep, the EPX-PB812 provides a substantial yet organised enclosure arrangement for demanding electrical distribution applications. The Protecta Power system supports 415 V AC operation, a 50 kA short-time withstand current for 1 second and IP43 enclosure protection when correctly assembled with the specified components, making it suitable for appropriately designed indoor low-voltage distribution installations.

Reliable High-Capacity Power Distribution for Modern Electrical Installations
High-capacity moulded case circuit breaker panelboards are essential components in commercial and industrial low-voltage electrical distribution systems. They provide a centralised arrangement for distributing electrical power to multiple outgoing circuits while accommodating suitable protective devices for overload, short-circuit and isolation requirements.
The ABB EPX-PB812 combines an 800 A rated busbar system with a 12-way outgoing configuration, providing a practical solution for electrical installations requiring substantial distribution capacity. Its rated short-time withstand current of 50 kA for 1 second supports appropriately engineered distribution assemblies where prospective fault levels and protective device coordination have been assessed.
ABB Protecta Power incorporates an innovative plug-in MCCB connection system using spring-loaded contacts. This arrangement reduces the number of conventional bolted circuit breaker connections and is designed to maintain reliable electrical contact during normal operation. The improved finger-safe busbar stack provides additional protection against accidental direct contact with internal busbar components.
The modular enclosure design also supports electrical system flexibility. Compatible ABB Tmax XT circuit breakers can be selected to provide the required circuit protection characteristics, while optional metering and monitoring accessories allow electrical engineers to incorporate power measurement and energy management functions into the completed distribution assembly.
With its 1700 × 1000 × 300 mm enclosure format, durable steel construction and coordinated cable entry arrangements, the EPX-PB812 is designed to support professional electrical panel building and long-term distribution system maintenance. The completed installation must be assembled in accordance with ABB instructions, with appropriate incoming and outgoing protective devices, connection kits, cable terminations and accessories selected for the required electrical performance.
