Description

Built for commercial power systems, the Square D GJL36070 is a 70A, 3-pole molded case circuit breaker from the legacy PowerPacT G-Frame series.

Product FAQs

4 answers
What does the 'J' in the GJL36070 catalog number indicate?

The 'J' designates the interrupting rating tier within the Square D PowerPacT G-Frame family. It signifies a high interrupting capacity, specifically rated for 65kA at 480VAC and 100kA at 240VAC.

What is the direct replacement or upgrade path for the GJL36070?

For legacy system upgrades, the PowerPacT G-Frame GJL36070 transitions to the newer PowerPacT H-Frame equivalent, catalog number HJL36070.

Is the GJL36070 compatible with I-Line panelboards?

No, the GJL36070 is a unit-mount (feed-thru) breaker designed for bolt-on installation in control panels and enclosures. It does not have the plug-on jaw connections required for Square D I-Line panelboards.

Are the thermal and magnetic trip settings adjustable on this breaker?

No, the GJL36070 features a fixed thermal-magnetic trip unit. Both the long-time (thermal) and instantaneous (magnetic) trip functions are factory-set and non-interchangeable.
