Why Choose the ABB EPX-8004SD 800A 4-Pole Switch Disconnector?
The ABB EPX-8004SD, manufacturer order code 1TVS151800S3375, is an 800 A four-pole switch disconnector based on the ABB Tmax XT6 platform. Designed for use as an incoming switching device in compatible ABB Protecta Power 800 A panelboards, it provides a dedicated solution for manual switching and electrical isolation in demanding low-voltage distribution installations.
Officially described as the EPX-8004SD 800A 4P SD - XT6, the product combines an 800 A device rating, four-pole configuration and ABB Tmax XT6 device platform. ABB lists it among the non-automatic incoming switch-disconnector options for its 800 A Protecta Power panelboard range.
The four-pole arrangement supports electrical distribution designs requiring the switching of four conductors, subject to the applicable neutral switching and earthing requirements. As a non-automatic switch disconnector, the EPX-8004SD is intended for switching and isolation rather than providing automatic overload or short-circuit protection.
For electrical contractors, switchgear manufacturers and professional panel builders, the ABB EPX-8004SD offers a manufacturer-designated incoming device for high-current Protecta Power assemblies. Its dedicated order code and associated XT6 connection accessories help simplify the specification of compatible distribution equipment.

ABB Tmax XT6 Incoming Switching for 800A Protecta Power Panelboards
The ABB Protecta Power system provides modular low-voltage distribution panelboards for commercial and industrial electrical installations. Its 800 A panelboard range is intended for applications requiring substantial distribution capacity, with incoming device options covering different current ratings, pole configurations and switching or protection functions.
The ABB EPX-8004SD is specifically listed as an 800 A four-pole XT6 non-automatic switch disconnector. It is intended for compatible Protecta Power incoming arrangements where the approved electrical design requires an 800 A isolation device rather than an incoming MCCB with automatic protective tripping.
ABB's 800 A Protecta Power panelboard family includes the EPX-PB808 8-way, EPX-PB812 12-way and EPX-PB818 18-way models. These provide different outgoing circuit capacities while sharing the same nominal 800 A busbar rating. The EPX-8004SD can be considered as part of an appropriately specified incoming arrangement for this panelboard family.
The four-pole configuration distinguishes the EPX-8004SD from the EPX-8003SD, which provides an equivalent 800 A XT6 switch-disconnector arrangement with three poles. Four-pole switching may be required in installations where the neutral conductor must be switched alongside the three phases. The correct arrangement depends on the earthing system, neutral conductor requirements and applicable electrical installation regulations.
As a non-automatic switch disconnector, the EPX-8004SD is intended for controlled switching and isolation. It should not be confused with a protective MCCB: the switch-disconnector function does not independently detect overloads or short circuits and operate an automatic protective trip. The electrical design must therefore include suitable protective equipment and coordination arrangements.
For connection to the Protecta Power distribution system, the corresponding accessory is the ABB EPX-8004CK 800 A four-pole XT6 incoming connection kit. This is a separately identified product and should not be assumed to be included with the EPX-8004SD. The correct kit and associated components must be selected for the intended panelboard configuration.
ABB's Protecta Power incoming device selection information identifies a maximum cable capacity of 2 x 120 mm² for XT6. This is a manufacturer-stated platform reference and is subject to the applicable terminal arrangement, conductor type and installation instructions. Cable selection must also account for current-carrying capacity, thermal conditions, fault withstand requirements and the overall electrical design.
For applications requiring cable lug connections, ABB identifies front extended terminals as an available option within its incoming device accessory range. Any additional terminal kits, shrouds, supports or cable management accessories must be verified for compatibility with the selected XT6 device and Protecta Power assembly.
ABB also offers the EPX-6304SD, a 630 A four-pole XT5 switch disconnector, for installations requiring a lower-rated incoming device. Where automatic incoming protection is required, suitable MCCB alternatives should be considered instead of a non-automatic switch disconnector. Device selection must reflect the required operating current, prospective fault level, protection strategy and isolation requirements.
The EPX-8004SD is an incoming switching device, not a complete electrical panelboard. A finished Protecta Power installation may require the panelboard enclosure, incoming connection kit, outgoing circuit breakers, metering accessories and other assembly components. The completed system must be assembled and verified in accordance with the manufacturer's instructions and applicable electrical standards.
