Typical Applications
Ideal for use in compatible ABB / GE load centers, lighting panels, and panelboards where bolt-on Q-Line branch circuit protection is required. Commonly used for feeder circuits, HVAC equipment, lighting circuits, appliance circuits, and other 120/240V loads.
Construction Details
Bolt-on connection provides a secure mechanical and electrical attachment to compatible panelboard bus structures.
Thermal-magnetic trip elements provide protection against overloads and short-circuit conditions.
Compact one-inch-per-pole design helps maximize panelboard circuit density.
Important Notes
Verify breaker compatibility with the specific panelboard or load center before installation.
Installation should be performed by qualified electrical personnel in accordance with applicable electrical codes.
Use THQB2130GFT where 30A 2-pole GFCI self-test protection is required.
