HGB3B045B - 45Amp Circuit Breaker Description
HGB3B045B - 45Amp Circuit Breaker
When you’re replacing a breaker, the small details matter just as much as the amp rating. The HGB3B045B is a 45A, 3-pole HGB G-frame circuit breaker made for compatible low-voltage panelboard applications. It uses a straightforward thermal-magnetic trip unit for overload and short-circuit protection, with interrupting ratings of 14 kAIC at 600Y/347V and 35 kAIC at 480Y/277V.
Key Features and Benefits
- 45-amp rating: Sized for circuits and equipment requiring a 45A breaker.
- Three-pole configuration: Provides three-pole protection in compatible panelboard systems.
- Thermal-magnetic trip: A proven design that responds to both overloads and short circuits.
- Load-side lug design: Equipped with TC1GG20 lugs for the specified load connection.
- Flexible conductor range: Accepts 8 AWG to 1/0 AWG copper or aluminum wire.
- Space-conscious G-frame size: The 3 x 5.4 x 2.8-inch dimensions make it easier to check fit in existing compatible equipment.

Material Compliance and Certifications
The HGB3B045B is UL Listed, an important point to verify when selecting electrical protection equipment for a specific panelboard or installation.
Available manufacturer data identifies an ECCN classification of EAR99 / AL N and states that the breaker is not classified as dangerous goods.
Where It Works Best
The HGB3B045B makes the most sense in compatible low-voltage panelboards and commercial or industrial electrical distribution equipment where a 45A, three-pole HGB G-frame breaker is specified. Its thermal-magnetic trip makes it a practical choice for applications requiring conventional overload and short-circuit protection.
