Product FAQs
6 answersWhat equipment is the NHL361200 designed to be installed in?
This unit mount breaker is designed for use in Square D QED switchboards and motor control centers.
Is the NHL361200 an I-Line plug-in breaker?
No. The NHL361200 is a unit mount, feed-thru circuit breaker that bolts directly to the bus or backpan. I-Line panelboards require a plug-in variant.
What type of trip unit is installed in the NHL361200?
It is equipped with a thermal magnetic trip unit that provides long-time and instantaneous (LI) protection functions. The thermal element is fixed, while the magnetic element is adjustable.
What size wire is accepted by the standard lugs on this 1200A breaker?
The standard factory lugs accept four 350 to 750 kcmil aluminum or copper conductors per phase.
Is the N-frame NHL361200 still in active production?
The N-frame is a legacy molded case circuit breaker. When upgrading or replacing this unit, facilities often transition to the modern Square D PowerPact P-frame series, such as the PJL36120U31A, using a compatible retrofit kit.
What safety precautions are required before servicing the NHL361200?
Always de-energize the switchboard or motor control center upstream before servicing. Verify the absence of voltage with a properly rated meter and wear appropriate arc flash PPE as required by NFPA 70E for 1200A equipment.
