Neutral Terminal Assembly · 150A · Single-Conductor Lug · Noark Electric NT-1A
SKU: NT-1A
150A neutral terminal assembly for Noark enclosed breaker and MCCB configurations, with a single-conductor lug for dedicated neutral termination. Commonly used where a field-installed neutral point is required in panel, disconnect, or enclosed breaker assemblies; verify enclosure and breaker compatibility before ordering.
What this product is for
The Noark NT-1A is a neutral terminal assembly rated 150A with a single-conductor lug. It is used to add a dedicated neutral termination point in compatible Noark enclosed circuit breaker and MCCB assemblies.
Use for
Use for enclosed breaker builds, control panels, main disconnect arrangements, and retrofit work where a neutral terminal is required within a compatible Noark configuration. It suits commercial and light industrial distribution applications that need a clean, dedicated neutral landing point.
Avoid for
Avoid using this accessory where the enclosure or breaker assembly is not listed for NT-series neutral terminals, where ampacity exceeds 150A, or where multiple conductor terminations are required on one lug. Do not assume universal fit across all MCCB brands or frame sizes.
Best for
Best for electricians and panel builders matching a Noark enclosed breaker assembly that calls for a 150A, 1-hole neutral option. It is a practical choice when maintaining listing compliance and using manufacturer-matched accessories matters.
Installed in
Typically installed inside compatible enclosed circuit breaker equipment, distribution assemblies, and panel-based power distribution setups. Final placement and conductor range should be confirmed against the specific enclosure and breaker documentation.
Why this product exists
This neutral assembly provides a manufacturer-designated neutral termination option for systems that require a neutral conductor in the enclosure. Using the correct accessory can simplify ordering, support code-compliant assembly practices, and reduce field improvisation.
Compared with similar products
Compared with higher-rated NT-series neutral assemblies, the NT-1A is the 150A version with a single terminal hole. It is intended for lower ampacity enclosed breaker applications than NT-2A, NT-3A, or NT-4B style options. As typical buying guidance, match the neutral assembly rating to the breaker/enclosure system rating and required conductor termination style. Actual suitability depends on equipment layout, conductor type, and local electrical code.
