GE THHQB1130 Miniature Circuit Breaker 30A 1 Pole 120/240V AC
A 30 A single-pole miniature circuit breaker rated 120/240 V AC with 22 kA interrupting capacity and bolt-on mounting for load centers
- 30 A rated current protects 120/240 V single-phase circuits
- 22 kA interrupting rating clears high fault currents safely
- Bolt-on mounting fits GE load centres and lighting panels
- Screw-clamp terminals accept wire down to 14 AWG
- Compact 3.3 × 1 × 2.4 in frame saves panel space
What This Breaker Is
The GE THHQB1130 is a single-pole miniature circuit breaker rated at 30 amps for 120/240 V AC systems. It belongs to the THHQB series and carries a 22 kA interrupting capacity at that voltage. The unit uses a bolt-on mounting style and a toggle actuator for manual switching.
How It Fits a Panel
This breaker occupies one pole space in compatible GE load centres or lighting panels that accept bolt-on THHQB frames up to 60 A. Screw-clamp terminals accept conductors down to 14 AWG, securing the circuit wiring without additional hardware. The 3.3 in length, 1 in width and 2.4 in depth allow it to sit flush beside other single-pole devices in the same row.
Who Should Use It
Electricians and facility managers needing a 30 A single-pole protector for standard AC branch circuits will find this breaker matches the spec. It is not suited for DC applications, multi-pole requirements, or panels that only accept plug-in breakers. Buyers who need a higher interrupting rating or a different frame size should look elsewhere.

Questions about this item
Will a 30 A breaker trip if the load exceeds 30 A continuously?
The breaker is rated 30 A; it will open the circuit when current exceeds that rating according to its time-current curve.
How much heat does the THHQB1130 generate during all-day operation?
Normal operation produces modest warmth; the bolt-on frame dissipates heat into the load-center bus, and the 22 kA interrupting rating indicates robust thermal performance.
What load-center bus style is required for this bolt-on breaker?
It mounts on GE bus connections rated for 60 A frame size, using screw-clamp terminals that accept wire down to 14 AWG.
