Why Choose the ABB EPX-8003SD 800A 3-Pole Switch Disconnector?
The ABB EPX-8003SD is a dedicated 800 A three-pole incoming switch disconnector designed for compatible ABB Protecta Power low-voltage electrical distribution panelboards. Based on the ABB Tmax XT6 device frame, this non-automatic switching device provides a manufacturer-specified solution for manually switching and isolating an incoming electrical supply. Its ABB order code is 1TVS151800S3374, and its official product description is EPX-8003SD 800A 3P SD - XT6.
Part of the ABB Protecta Power Enclosures product group, the EPX-8003SD combines an 800 A rated current with a three-pole configuration for suitable three-phase electrical distribution arrangements. It is intended for installations where the incoming supply requires a switch disconnector rather than a moulded case circuit breaker incorporating automatic overload and short-circuit protection.
ABB lists the EPX-8003SD among its non-automatic incoming switch disconnectors for Protecta Power 800 A busbar panelboards. The product pack contains the incoming device, while the corresponding connection kit and any additional terminal accessories must be selected according to the intended panelboard arrangement. This makes the EPX-8003SD suitable for electrical contractors, switchboard manufacturers and panel builders specifying coordinated ABB power distribution equipment.

800A Three-Pole Incoming Switching for Protecta Power Distribution Systems
The ABB Protecta Power system provides a modular platform for low-voltage electrical distribution in commercial and industrial installations. Its 800 A busbar panelboard range accommodates different incoming switching and protective devices, allowing the assembly to be configured for the electrical installation's requirements. The EPX-8003SD is specifically identified as an 800 A three-pole XT6 non-automatic switch disconnector within this range.
A switch disconnector performs a different role from a moulded case circuit breaker. The EPX-8003SD is intended for manually switching and isolating an electrical supply and does not provide automatic overload or short-circuit tripping. Appropriate fault protection must therefore be provided elsewhere in the installation, with the switching device selected and coordinated according to its applicable electrical ratings and the complete system design.
The three-pole configuration is intended for switching the three phase conductors in a suitable three-phase supply arrangement. Neutral conductor treatment must be determined separately according to the installation's earthing system and applicable regulations. Where a four-pole switching arrangement is required, ABB lists the related EPX-8004SD XT6 switch disconnector.
ABB's Protecta Power selection information identifies a maximum cable capacity of 2 × 120 mm² for XT6 incoming devices. This manufacturer selection-guide value must be considered alongside the actual terminal configuration, conductor construction, cable termination method and installation conditions. ABB also offers front extended terminals for suitable lug connections, subject to the relevant device and assembly instructions.
For installation within a compatible Protecta Power panelboard, ABB lists the EPX-8003CK as the corresponding 800 A three-pole XT6 incoming connection kit. This connection kit provides the specified incomer support, shrouding and busbar connectivity components. The incoming switch disconnector and connection kit are distinct products, so both must be considered when specifying the complete assembly.
Related ABB Protecta Power incoming devices include the EPX-6303SD, a 630 A three-pole XT5 switch disconnector, and the EPX-8004SD, an 800 A four-pole XT6 switch disconnector. Where automatic overcurrent protection is required at the incomer, ABB also offers the EPX-8003MCCB and EPX-8003-E1-MCCB XT6 incoming circuit breaker options. Selection must reflect the required switching functionality, protective coordination and distribution assembly compatibility.
