Why Choose the ABB EPX-PB408 400A 8-Way Panelboard?
The ABB EPX-PB408, manufacturer order code 1SKV413140S0001, is a 400 A, 8-way MCCB distribution panelboard from the ABB Protecta Power range. Designed for professional low-voltage power distribution, this panelboard provides a modular platform for configuring incoming and outgoing electrical circuits in commercial, industrial and infrastructure installations.
Featuring a 400 A rated busbar system and eight outgoing ways, the EPX-PB408 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 switchroom planning and electrical panelboard installation.
The ABB Protecta Power system combines modular construction with a finger-safe busbar design, plug-in circuit breaker connections and a range of compatible accessories. These features help electrical contractors and panel builders configure distribution assemblies to suit project requirements while supporting accessible installation and maintenance.
As the 8-way model in ABB's 400 A Protecta Power panelboard range, the EPX-PB408 is suitable for applications requiring a compact selection of outgoing MCCB circuits. The final electrical configuration, including incoming devices, outgoing breakers, metering and additional accessories, must be selected according to the relevant ABB technical documentation.

400A MCCB Power Distribution with ABB Protecta Power
The ABB Protecta Power system is designed for low-voltage electrical distribution applications requiring modular construction, configurable circuit protection and accessible installation arrangements. The range includes 400 A and 800 A panelboard options, allowing electrical designers to select equipment according to the intended distribution capacity and number of outgoing circuits.
The ABB EPX-PB408 provides an 8-way, 400 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 400 A Protecta Power main panelboard selection, which also includes the EPX-PB412 12-way and EPX-PB418 18-way variants.
The panelboard is designed for integration with compatible ABB Tmax XT moulded-case circuit breakers. ABB's Protecta Power platform uses spring-loaded plug-in circuit breaker connections, helping reduce the need for conventional bolted connections at compatible outgoing device interfaces. The manufacturer's finger-safe busbar stack is designed to meet IP20 protection requirements at that component level.
For incoming power arrangements, the 400 A Protecta Power system supports appropriately selected ABB Tmax XT devices. ABB's product selection literature includes XT4 250 A and XT5 400 A incoming switch-disconnector options in three-pole and four-pole configurations. The appropriate incoming device must be chosen according to the electrical design, protection requirements and approved panelboard assembly.
The 50 kA for 1 second short-time withstand rating specified for the EPX-PB408 relates to the panelboard's rated short-time withstand capability. It should not be confused with the breaking capacity of an individual MCCB, which depends on the selected circuit breaker and its operating voltage.
ABB Protecta Power also offers compatible accessories for cable routing, metering, surge protection and enclosure expansion. These options can help electrical designers adapt a distribution assembly to building infrastructure requirements. The availability and suitability of each accessory must be checked against the selected panelboard configuration.
The EPX-PB408 panelboard should not be assumed to include all incoming and outgoing protective devices. The final assembly specification must identify the required MCCBs, incoming connections, protective devices, metering equipment and accessories. Electrical ratings, ingress protection and compliance of the completed distribution board depend on the approved assembly and correct installation.
