Looking to protect circuits up to 100 Amps?

Add an NK ground fault relay to your shunt trip breaker to create a cost-effective solution.

Begin Here >

Do you have a Square D panelboard, and need a 2 pole (up to 50 A) GFCI breaker or 3 pole (50 A to 100 A) GFCI breaker?

Combine an NK Technologies AC ground fault relay and Square D breaker with shunt trip option to make 5 mA ground fault circuit interrupter solution. This combination includes current overload protection.

Or - Do you have an ABB, Allen Bradley, Cutler Hammer, EATON, GE, Siemens or any Other panelboard/load center and need 3-pole (208 VAC) GFCI breaker for a 15 to 100 A branch circuit?

Save material and labor costs by using NK Technologies AC ground fault relay and a breaker (from your OEM) with a shunt trip option to make a 5 mA ground fault circuit interrupter solution. This combination includes current overload protection as well.

Here is what Engineers have to say about our technical expertise...

“Changes to NEC 210.8 B-F have challenged all of us in the industry to find new GFCI solutions. When NK Technologies reached out to us recently, we decided to invest a few hours into meeting with their application experts. Five of our electrical engineering designers attended the session and considered it time well spent. NK Technologies has an in-depth understanding of the new NEC requirements and ground fault products designed to meet them. We are thankful for their time.”
