GE THQB 1-Pole 20A 120/240V HID Bolt-On Breaker

SKU CH-DKVT-F488D

Single-pole 20 A HID bolt-on breaker rated 120/240 V AC with 10 kA interrupting capacity for lighting panels and load centres

  • HID-rated breaker protects high-intensity discharge lighting circuits
  • 20 A single-pole design handles 120/240 V AC panel loads
  • 10 kA interrupting rating clears faults safely at rated voltage
  • Bolt-on mounting fits GE THQB load centres and panels directly
  • Screw-clamp terminals accept 14 AWG Cu or 12 AWG Al conductors

20 A HID Bolt-On Breaker

The GE THQB 1-pole 20 A 120/240 V breaker is designed for high-intensity-discharge lighting loads in residential or light-commercial panels. It fits single-phase load centres that accept the THQB bolt-on frame and protects HID circuits with a dedicated trip curve. Electricians wiring new or retrofit lighting panels will find it matches the required frame size and voltage rating.

10 kA interrupting at 120/240 V AC

The breaker carries a maximum AIR of 10 kA at 120/240 V AC and is not rated for DC applications. It mounts only on bolt-on bus bars and accepts copper wire down to 14 MCM or aluminium down to 12 MCM via screw-clamp terminals. Panels requiring a higher interrupting rating or a different mounting style cannot use this device.

Bolt-on mounting with screw-clamp terminals

Installation consists of bolting the 3.5 in by 1 in frame onto the panel bus and tightening the screw-clamp terminals onto prepared conductors. The toggle actuator provides clear on-off indication. Common issues include mismatching the bolt-on foot pattern to a plug-on panel, using undersized wire below the 14 MCM copper minimum, or applying the breaker to non-HID loads that need a standard trip curve.

Questions about this item

Should I pick the 20 A single-pole version or a different amp rating for my lighting panel?

Choose the 20 A single-pole breaker when the circuit is rated for 20 amps; other amp ratings in the THQB series protect different load levels and will not fit the same design current.

What does the 10 kA interrupting rating mean once the breaker is installed in a load centre?

It means the breaker can safely clear a fault current up to 10 kA at 120/240 V AC without damage, so the panel’s available fault current must not exceed that value.

How does the bolt-on mounting style limit where this THQB breaker can be used?

The bolt-on base only fits GE load centres and lighting panels designed for the THQB frame; it will not snap into plug-on or competitive panel boards.
