Neutral terminal assembly · 250A · single-conductor lug configuration · Noark Electrical NT-2A
SKU: NT-2A
250A neutral terminal assembly for Noark enclosed breaker and MCCB applications requiring a single-conductor lug configuration. Commonly used where a dedicated neutral termination is needed in 3P-4W assemblies; confirm enclosure and breaker compatibility before ordering.
What this product is for
The NT-2A is a neutral terminal assembly used with compatible Noark enclosed breaker and MCCB assemblies where a 250A neutral connection is required. It provides a factory-matched neutral terminal option for 3-phase, 4-wire distribution equipment.
Use for
Use for 250A enclosed breaker builds, panel modifications, or replacement neutral terminal assemblies where the equipment is designed to accept a Noark NT-series neutral terminal. It is suited to commercial and industrial distribution applications that require a dedicated neutral landing point.
Avoid for
Avoid using this accessory as a universal neutral bar or as a substitute for a different frame size, hole pattern, or manufacturer-specific neutral kit. Do not assume cross-compatibility with other breaker lines or panelboards without confirming the exact Noark assembly requirements.
Best for
Best for electricians and panel builders ordering a correct replacement or specifying a 250A neutral terminal for a Noark enclosed breaker assembly. It is also a practical choice when matching listed accessories to maintain a code-compliant installation.
Installed in
Typically installed in compatible enclosed circuit breaker equipment and MCCB-based distribution assemblies. Final fit depends on the Noark enclosure series, breaker frame, and neutral terminal selection guide for the assembly.
Why this product exists
Some enclosed breaker applications require a dedicated neutral termination rather than a 3-wire configuration. The NT-2A exists to provide a matched 250A neutral terminal option within the Noark NT product family, helping contractors order the correct accessory for 3P-4W equipment layouts.
Compared with similar products
Within the Noark NT family, NT-1A is the 150A version and NT-3A is the 400A version, while NT-3B and NT-4B move to 2-hole terminal configurations at higher ampacities. The NT-2A is the 250A, 1-hole option, making it the correct choice when the project calls for that specific current rating and lug style.
Typical buying guidance: neutral terminal accessories must match the listed equipment and conductor termination style. Actual fit and conductor acceptance depend on the equipment design, wire size, bending space, and local electrical code.
