Why Choose the ABB EPX-6304SD 630A 4-Pole Switch Disconnector?
The ABB EPX-6304SD is a 630 A four-pole incoming switch disconnector designed for compatible ABB Protecta Power low-voltage electrical distribution panelboards. Built around the ABB Tmax XT5 frame, this non-automatic switching device provides a dedicated solution for manually switching and isolating an incoming electrical supply. Its ABB order code is 1TVS151800S3373, and its manufacturer product description is EPX-6304SD 630A 4P SD - XT5.
Part of the ABB Protecta Power Enclosures product group, the EPX-6304SD is designed for incoming supply arrangements requiring a 630 A rated current and four-pole switching configuration. It is particularly suited to three-phase distribution systems where the installation design calls for switching of the three phase conductors and neutral, subject to the applicable earthing arrangement and electrical installation requirements.
ABB lists the EPX-6304SD among its non-automatic incoming switch disconnectors for Protecta Power 800 A busbar panelboards. The product pack contains the incoming switching device, while the appropriate connection components and any additional terminal accessories must be selected for the complete distribution assembly. This makes the EPX-6304SD a manufacturer-specified choice for electrical contractors, switchboard manufacturers and panel builders working with ABB Protecta Power systems.

630A Four-Pole Incoming Switching for Protecta Power Distribution Systems
The ABB Protecta Power range provides a modular approach to low-voltage electrical distribution, with incoming switching devices selected to suit different panelboard ratings and supply configurations. The EPX-6304SD is listed in ABB's 800 A busbar panelboard incoming device range as a 630 A four-pole XT5 non-automatic switch disconnector. Its rating and configuration make it suitable for incoming switching arrangements where the complete electrical installation has been designed around the relevant device characteristics.
A switch disconnector is different from a moulded case circuit breaker with an automatic protection trip unit. The EPX-6304SD is intended to provide switching and isolation functionality rather than automatically responding to overloads or short circuits. Suitable upstream or otherwise coordinated protective devices must therefore be provided to address the installation's fault protection requirements. The switch disconnector's operational and isolation suitability must also be verified against the applicable ABB device documentation.
The four-pole configuration provides switching positions for a three-phase and neutral arrangement where neutral switching is permitted and required by the electrical system design. The appropriate treatment of the neutral conductor depends on the earthing system, installation regulations and the complete switching arrangement. The EPX-6304SD should therefore be selected according to the intended electrical distribution configuration rather than pole count alone.
ABB's Protecta Power selection information lists a maximum cable capacity of 185 mm² for XT5 incoming devices. This is a general selection-guide value and does not remove the need to verify the actual terminals, conductor type, termination method and installation conditions. ABB also identifies front extended terminals as an available option for suitable cable lug connections. The correct connection kit and terminal accessories must be selected separately where required by the panelboard assembly.
Related ABB Protecta Power incoming switching options include the EPX-6303SD, a 630 A three-pole XT5 switch disconnector, and the EPX-8004SD, an 800 A four-pole XT6 switch disconnector. ABB also offers the EPX-6304MCCB for installations requiring a 630 A four-pole XT5 incoming circuit breaker with automatic protection functionality. These alternatives should be selected according to the incoming supply rating, pole configuration and electrical protection design.
