Why Choose the ABB EPX-2503SD 250A 3-Pole Switch Disconnector?
The ABB EPX-2503SD is a 250 A three-pole switch disconnector designed for use as an incoming device in compatible ABB Protecta Power electrical distribution panelboards. Based on the ABB Tmax XT4 frame, this non-automatic switching device provides a dedicated means of manually switching and isolating the incoming supply within a suitable low-voltage distribution assembly. Its ABB order code is 1TVS151800S3360.
Part of the ABB Protecta Power Enclosures product group, the EPX-2503SD is intended for installations where the incoming supply requires a switch disconnector rather than a moulded case circuit breaker with an overcurrent protection trip unit. Its 250 A current rating and three-pole configuration make it suitable for appropriately designed three-phase distribution arrangements, subject to the installation's electrical and isolation requirements.
ABB lists the EPX-2503SD among the non-automatic incoming switch disconnectors for its Protecta Power 400 A busbar panelboard range. The incoming device is supplied as part of the specified product pack, while the appropriate connection arrangement and any additional accessories must be selected to suit the complete panelboard installation. This makes the EPX-2503SD a practical choice for electrical contractors, switchboard manufacturers and panel builders working with ABB Protecta Power systems.

250A Incoming Switching and Isolation for Protecta Power Panelboards
The ABB Protecta Power system provides a modular platform for low-voltage electrical distribution, with a range of incoming devices designed to suit different panelboard configurations. The EPX-2503SD belongs to ABB's non-automatic switch disconnector selection for compatible 400 A busbar panelboards. Its 250 A rating and XT4 three-pole configuration identify the intended incoming switching arrangement.
A switch disconnector differs from a moulded case circuit breaker because it is primarily intended to provide switching and isolation rather than automatic fault protection. The EPX-2503SD does not incorporate the overload and short-circuit trip functions associated with an MCCB. Where fault protection is required, suitable protective devices must be provided elsewhere in the electrical installation and coordinated with the switch disconnector's applicable ratings.
ABB identifies the EPX-2503CK as the corresponding 250 A three-pole XT4 incoming connection kit within the Protecta Power accessory range. Incoming connection kits provide the necessary support, shrouding and busbar connectivity for the specified arrangement. The correct connection kit and any additional terminal accessories should be selected according to ABB's installation instructions and the chosen panelboard configuration.
For XT4 incoming devices, ABB's Protecta Power selection information lists a maximum cable capacity of 150 mm². Actual conductor suitability depends on the terminal arrangement, conductor construction, cable termination method and applicable installation requirements. ABB also identifies front extended terminals as an available option for suitable lug connections. These details should be checked against the relevant device and assembly documentation before installation.
Related incoming switching options include the EPX-2504SD, which provides a 250 A four-pole XT4 configuration, and the EPX-4003SD, which provides a 400 A three-pole XT5 configuration. For installations requiring automatic overcurrent protection, ABB also offers dedicated XT4 MCCB incoming devices. The appropriate product must be selected according to the supply arrangement, switching requirements and overall protection design.
