Why Choose the ABB EPX-PB808 800A 8-Way Panelboard?
The ABB EPX-PB808, manufacturer order code 1SKV413149S0001, is an 800 A, 8-way MCCB distribution panelboard from the ABB Protecta Power range. Designed for professional low-voltage electrical distribution, this panelboard provides a modular platform for configuring incoming and outgoing circuits in commercial, industrial and infrastructure installations.
Featuring an 800 A rated busbar system and eight outgoing ways, the EPX-PB808 supports the distribution of electrical power through appropriately selected ABB Tmax XT moulded-case circuit breakers. Its nominal enclosure dimensions of 1400 mm high x 1000 mm wide x 300 mm deep provide a defined footprint for electrical plant room planning and switchgear installation.
The ABB Protecta Power system combines modular construction with a finger-safe busbar arrangement, spring-loaded plug-in circuit breaker connections and a comprehensive selection of compatible accessories. These features support efficient panelboard assembly, flexible circuit protection configurations and straightforward integration into modern low-voltage distribution systems.
As the 8-way model within ABB's 800 A Protecta Power panelboard range, the EPX-PB808 is suitable for installations requiring high-current distribution capacity with a defined number of outgoing MCCB circuits. Incoming devices, outgoing breakers, metering equipment and additional accessories must be selected according to the electrical design and applicable ABB assembly instructions.

800A MCCB Power Distribution with ABB Protecta Power
The ABB Protecta Power system is designed for low-voltage electrical distribution installations requiring high-current capacity, modular construction and configurable circuit protection. The range includes 400 A and 800 A panelboard options, allowing electrical designers to select equipment according to the required distribution capacity and number of outgoing circuits.
The ABB EPX-PB808 provides an 8-way, 800 A panelboard configuration with nominal dimensions of 1400 mm x 1000 mm x 300 mm. It is the smallest way-count option within ABB's 800 A Protecta Power main enclosure selection, which also includes the EPX-PB812 12-way and EPX-PB818 18-way variants.
The Protecta Power platform uses spring-loaded plug-in circuit breaker connectors for compatible outgoing devices. This arrangement reduces reliance on conventional bolted connections at the plug-in interface and is designed to support reliable electrical contact. ABB also incorporates an improved IP20 finger-safe busbar stack to help reduce the risk of accidental contact during appropriate installation and maintenance activities.
For incoming power arrangements, the 800 A Protecta Power panelboard range supports suitably selected ABB Tmax XT devices. ABB lists XT5 630 A and XT6 800 A incoming switch-disconnector options in three-pole and four-pole configurations. The final incoming device must be selected according to the installation's load, fault level, protection requirements and approved assembly design.
The Protecta Power technical specification identifies a 50 kA for 1 second rated short-time withstand current. This rating describes the specified withstand capability of the distribution assembly and should not be confused with the short-circuit breaking capacity of an individual MCCB. The breaking capacity of each protective device depends on the selected circuit breaker and its operating voltage.
The system also provides options for Form 3b Type 2 segregation in three-pole arrangements and Form 4b Type 6 segregation in four-pole arrangements, subject to the specified assembly configuration. These arrangements support the separation of functional units and connections in accordance with the relevant switchgear assembly design.
For projects requiring electrical monitoring, ABB Protecta Power can be configured with compatible ABB Tmax XT circuit breakers, metering devices and communication accessories. Depending on the selected equipment, these technologies can support measurement, energy monitoring and communication with building or facility management systems.
The EPX-PB808 should not be assumed to include all incoming and outgoing MCCBs, metering equipment or optional accessories. The final distribution assembly must be specified with the appropriate electrical devices, connection kits, protective arrangements and enclosure components. Electrical performance and compliance depend on the complete verified assembly rather than the panelboard enclosure alone.
