Condition

THHQB1120 panelboard note: ABB's GE-branded THHQB1120 is a high-interrupt Q-Line breaker that bolts to the bus rather than clipping in like a residential plug-in device. It provides fixed thermal-magnetic protection for a 20-amp single-pole circuit.

THHQB1120 specifications

  • Catalog number: THHQB1120
  • Rating: 20A, 1-pole, 120/240VAC class
  • Interrupting rating: 22kA
  • Mounting: Q-Line bolt-on
  • Trip: Non-interchangeable thermal-magnetic

THHQB versus plug-in Q-Line

The bolt-on bus connection is the key fit feature. A similarly rated THQL or another Q-Line case is not a substitute unless the equipment documentation expressly lists it.

Equipment match

Verify the panelboard label accepts THHQB, and compare pole count, system voltage, available fault current, lug range, and accessory requirements. The breaker should be installed on de-energized equipment using the specified hardware and torque by a qualified electrical professional.

There is a $15 charge for delivery. Additional charges will be imposed by our couriers for delivery to remote areas, a surcharge may be levied to cover carriage to these areas.
