Why Choose the ABB EPX-4004SD 400A Four-Pole Switch Disconnector?
The ABB EPX-4004SD is a purpose-designed 400 A four-pole switch disconnector for compatible ABB Protecta Power electrical distribution panelboards. Based on the ABB Tmax XT5 device platform, this incoming switching device provides a dedicated means of manually switching and isolating the electrical supply to a low-voltage distribution assembly.
Part of the ABB Protecta Power Enclosures range, the EPX-4004SD is designed for use as an incoming non-automatic switch disconnector within compatible 400 A panelboard configurations. Its four-pole (4P) arrangement supports switching of three-phase conductors and a neutral conductor where required by the approved installation design.
Developed for electrical contractors, switchgear manufacturers and panel builders, the EPX-4004SD provides a coordinated incoming switching solution for ABB Protecta Power distribution systems. With a 400 A current rating, XT5 frame configuration and manufacturer order code 1TVS151800S3363, this genuine ABB component is suitable for commercial and industrial power distribution installations requiring a compatible four-pole incoming switch disconnector.

Reliable 400A Incoming Switching with ABB Tmax XT5 Technology
The incoming device is an important part of a low-voltage electrical distribution panelboard. It provides a designated switching point between the incoming electrical supply and the distribution system, supporting controlled operation and electrical isolation when installed and used in accordance with the applicable safety procedures.
The ABB EPX-4004SD is designed for this role within compatible 400 A ABB Protecta Power panelboards. Its XT5 four-pole configuration provides switching functionality for installations where the electrical design requires three-phase conductors and a neutral conductor to be switched together.
ABB identifies the EPX-4004SD as a non-automatic switch disconnector, distinguishing it from the MCCB incoming devices also available for the Protecta Power system. A switch disconnector provides switching and isolation functionality but does not independently provide the automatic overload or short-circuit protection associated with an appropriately specified circuit breaker.
The ABB Protecta Power range includes 250 A XT4 and 400 A XT5 incoming switch disconnectors in three-pole and four-pole configurations. For a 400 A installation, the EPX-4003SD provides the three-pole XT5 option, while the EPX-4004SD provides the four-pole XT5 option. Selecting the appropriate pole configuration is essential for compatibility with the electrical supply arrangement and installation requirements.
The Protecta Power 400 A panelboard range includes 8-way, 12-way and 18-way configurations. The EPX-4004SD is intended for compatible incoming arrangements within this range, subject to the approved panelboard design and the correct connection accessories.
ABB's Protecta Power product selection information identifies a maximum XT5 incoming cable capacity of 185 mm² for the relevant incoming device arrangement. Actual conductor suitability depends on the selected terminals, cable type, installation conditions and manufacturer's instructions. The complete installation must also include the necessary upstream or associated overcurrent protection and comply with the applicable electrical standards.
