Description
Part of the HEG series, this 70A, 3-pole molded case circuit breaker is engineered for commercial and industrial power distribution up to 600VAC. Designed to install into legacy Federal Pacific panelboards, the bolt-on unit serves as an exact cross-reference for older NEG631070 and NEF631070 models. This ensures a proper fit without the need for aftermarket adapters. Rated at 22 kAIC at 480V, the breaker utilizes fixed thermal-magnetic trip elements to quickly clear electrical faults.Specifications

Product FAQs
6 answersWhat older Federal Pacific breakers does the HEG631070 replace?
The HEG631070 serves as a direct substitute for discontinued Federal Pacific NEF631070 and NEG631070 70-amp, 3-pole circuit breakers.
What type of panelboards will accept the HEG631070 breaker?
This breaker is specifically designed for use with legacy Federal Pacific panelboards that accommodate H-frame bolt-on circuit breakers.
Is the HEG631070 compatible with modern panelboards from other manufacturers?
No. This is a legacy Federal Pacific H-frame breaker designed exclusively for older Federal Pacific panelboards. It will not mount onto the bus of modern panels from brands like Square D, Eaton, or Siemens.
Are the thermal and magnetic trip functions adjustable on this breaker?
No, the HEG631070 features a thermal-magnetic trip unit with fixed long-time and fixed instantaneous (LI) settings. Neither the thermal nor the magnetic trip points can be adjusted in the field.
What are the minimum and maximum wire sizes accepted by the HEG631070 lugs?
The load side terminals accept conductors as small as 14 AWG and as large as 1/0 AWG. When sizing your wire, verify that the conductor ampacity aligns with the 70-amp rating of the breaker and local electrical codes.
Does this breaker plug in or bolt on to the panel bus?
The HEG631070 utilizes a bolt-on connection. It must be mechanically fastened to the panelboard bus with hardware, which provides a highly secure connection for commercial and industrial applications.
