HGB3B090B - 90Amp Circuit Breaker Description
HGB3B090B - 90Amp Circuit Breaker
If you’re trying to match an existing breaker, HGB3B090B gives you a very specific electrical and mechanical profile to work from. This 90-amp, 3-pole HGB G-frame circuit breaker is designed for compatible low-voltage panelboard applications and uses a thermal-magnetic trip unit to protect against overload and short-circuit conditions. For maintenance crews, electricians, and facility teams, the HGB3B090B is a practical choice when the job calls for this exact 90A, three-pole HGB configuration—not just a breaker with a similar amp rating.
Key Features and Benefits
- 90A, 3-pole configuration: Designed for compatible three-pole electrical applications requiring a 90-amp breaker.
- Thermal-magnetic protection: Responds to both sustained overloads and short-circuit conditions.
- HGB G-frame design: Built for low-voltage panelboard installations that use the corresponding frame configuration.
- TC1GG20 load-side lugs: Gives installers a clearly defined load-side connection setup.
- 8 AWG–1/0 AWG conductor range: Accepts copper or aluminum conductors within the specified wire sizes.

Material Compliance and Certifications
The HGB3B090B is UL Listed, which gives electrical professionals a recognized certification point when checking compatibility with a particular panelboard or installation.
Where It Works Best
The HGB3B090B is best suited to compatible low-voltage panelboards and commercial or industrial electrical distribution systems that specifically call for a 90A, 3-pole HGB G-frame breaker with thermal-magnetic protection.
It is particularly useful in maintenance and replacement work where the existing equipment requires the same frame, voltage rating, interrupting capacity, lug arrangement, and conductor range.
