Description
Designed to handle heavy electrical loads, the ABB NS361000 provides 65kAIC interrupting capacity at 240V. This 3-pole, 1000A molded case circuit breaker utilizes a thermal-magnetic trip mechanism with adjustable magnetic settings for precise circuit protection. It is engineered for bolt-on installation in compatible Eaton and Westinghouse switchboards. Facility managers can utilize this unit as a reliable substitute for discontinued Series C ND31000, HND31000, and CN31000 breakers.Specifications

Product FAQs
6 answersWhich panelboards are compatible with the NS361000 circuit breaker?
This N-Frame breaker is an exact fit for legacy Eaton and Westinghouse PRL4 panelboards and switchboards.
What legacy Westinghouse circuit breakers can the NS361000 replace?
It serves as a direct drop-in substitute for older Westinghouse HNB31000 and ND31000 units without requiring a retrofit kit.
What are the wire size requirements for the load side lugs on this breaker?
The load side lugs are designed to accept four conductors per phase, accommodating wire sizes from 3/0 AWG up to 500 kcmil.
How does the trip unit on the NS361000 function?
It utilizes a non-interchangeable thermal-magnetic trip unit that provides fixed long-time protection and adjustable magnetic settings for instantaneous (LI) overcurrent protection.
How is the NS361000 installed into the electrical system?
It features a bolt-on connection type, allowing it to be bolted directly to the busbars of compatible Eaton and Westinghouse switchboards.
Can this 1000A breaker be used in 480V and 600V industrial applications?
Yes, it is rated for use in systems up to 600VAC, providing a maximum interrupting capacity of 30kA at 480VAC and 25kA at 600VAC.
