Description
Engineered for high-capacity power distribution, the NC361000 is a 1000A molded case circuit breaker. It utilizes thermal-magnetic technology for dependable LI protection. This component plugs into Square D I-Line panelboards and switchboards. It serves as a legacy solution, with modern replacements available in the PowerPacT P-Frame series. Boasting a 100kA rating at 480VAC, it safely clears severe faults. The adjustable magnetic trip allows customization of the instantaneous response.Specifications

Product FAQs
4 answersWhat equipment is the NC361000 designed to be installed in?
This breaker features an I-Line style plug-in connection and is specifically designed for use in Square D I-Line panelboards and switchboards. It is not compatible with standard unit-mount enclosures or QO-style load centers.
Is the Square D NC361000 still manufactured, or is there a direct replacement?
The NC361000 is a legacy N-frame molded case circuit breaker. Square D has transitioned to the PowerPact P-Frame series, such as the PJA36100, for modern replacements in 1000A I-Line applications.
How does the adjustable magnetic trip function benefit the NC361000?
While the thermal element provides fixed long-time overload protection, the adjustable magnetic element allows you to fine-tune the instantaneous short-circuit response. This adjustability helps electricians properly coordinate the breaker with downstream protective devices.
What are the lug wire size requirements for the NC361000?
The breaker is equipped with multi-barrel lugs that accept four 3/0 AWG to 600 kcmil aluminum or copper conductors per phase, accommodating the large parallel wire runs typical of 1000A services.

Was happy with all the service would’ve wished the person would inform me if I would’ve spent $15 more I could’ve got free shipping. That way I could’ve ordered another 20 amp circuit breaker. And got it for free.

I wasn't sure about ordering my particular breakers online because they don't make replica replacements but found the warranty outstanding. The follow-up call as a new customer and the speed with which my order was processed and completed was superior. The price was 1/3 what the ONE local supplier charged.
