Why Choose the ABB EPX-NLXT4 XT4 Neutral Link >250 A?
The ABB EPX-NLXT4 (1SDA123192R1) is a dedicated XT4 neutral link designed for use within ABB Protecta Power low-voltage distribution assemblies. As part of the ABB Protecta Power enclosure and distribution system, this accessory provides a neutral connection arrangement for compatible outgoing moulded case circuit breaker (MCCB) installations.
Specifically identified for ABB Tmax XT4 outgoing MCCB applications, the EPX-NLXT4 supports the organisation of neutral conductors within distribution equipment. Its application in the Protecta Power system helps electrical panel builders establish a coordinated neutral connection arrangement alongside three-pole outgoing circuit breakers.
The EPX-NLXT4 is specified as an XT4 neutral link for >250 A applications under ABB order code 1SDA123192R1. It is intended for appropriately engineered Protecta Power assemblies, including compatible group-mounted Form 4 Type 2/6 arrangements. The neutral link is an electrical connection accessory rather than a protective switching device, and its suitability must be assessed against the complete distribution assembly design.

Reliable Neutral Connections for Low-Voltage Power Distribution
Neutral links provide connection points for neutral conductors within electrical distribution systems. Where three-pole moulded case circuit breakers are used to control and protect phase conductors, a separate neutral connection arrangement may be required according to the electrical system design. Correct selection and installation of neutral connection components are important for maintaining conductor continuity and supporting reliable distribution board operation.
The ABB EPX-NLXT4 is designed for the outgoing section of compatible ABB Protecta Power assemblies incorporating Tmax XT4 MCCBs. Its dedicated application within the manufacturer's modular distribution system supports coordinated panel construction and component compatibility. Electrical designers and installers must verify the required neutral conductor capacity, connection arrangement, installation conditions and complete assembly rating before commissioning.
Typical Applications
- ABB Protecta Power low-voltage distribution assemblies.
- Outgoing circuits using ABB Tmax XT4 three-pole MCCBs.
- Commercial electrical power distribution switchboards.
- Industrial low-voltage distribution panels.
- Group-mounted Form 4 Type 2/6 switchgear arrangements.
- Electrical installations requiring separate neutral conductor connections.
- Modular distribution board construction and assembly.
- Maintenance and replacement of compatible Protecta Power neutral connection accessories.
