The ETNKT2350T is an Eaton replacement trip unit rated 350A, 2-Pole, designed for use within the Eaton NKT-frame moulded-case circuit breaker series. Trip units are frame-specific and must match the breaker's pole count, ampere rating, and trip unit mounting interface — substitutions across frames or brands are not supported. This unit is intended for commercial and industrial panelboards and switchboards, not residential loadcentres. Have your existing breaker's full catalogue number on hand? Send it to our team and we'll confirm fitment.
The ETNKT2350T is designed specifically for Eaton NKT-frame circuit breakers in a 2-pole, 350A configuration. Trip unit compatibility is determined by the breaker frame, pole count, and amp rating — not all NKT-frame breakers share the same trip unit interface. We recommend providing your full breaker catalogue number so our team can confirm the correct match before you order.
In many cases, yes — Eaton's NKT-frame breakers are designed with field-replaceable trip units, which can make replacing the trip unit a cost-effective alternative to full breaker replacement, especially for hard-to-find or older units. However, the replacement must be an exact match in frame, poles, and amp rating. Our team can help verify whether your specific breaker supports this approach.
Eaton NKT-series components can be difficult to source through standard distribution channels. Northern Breaker Group specializes in obsolete and hard-to-find breaker parts across Canada.
