GE THHQB 30 A 3 Pole 240 V AC Circuit Breaker

SKU CH-HKMY-TFDS8

A 30 A, three-pole miniature circuit breaker rated 120/240 V AC with a 22 kA interrupting capacity and bolt-on mounting for load centres

  • High interrupting capacity up to 22 kA at 120/240 V AC
  • Three-pole design protects 120/240 V AC three-phase circuits
  • 30 A rating with 60 A frame fits standard load centres
  • Bolt-on mounting secures directly to bus connections
  • Screw-clamp terminals accept wire down to 14 AWG

Product Identity

The GE THHQB 30 A three-pole breaker provides high-interrupting protection at 120/240 V AC for three-phase load centres and lighting panels. It is built for electricians and facility managers who need a 22 kA AIR rating in a bolt-on frame.

Bundled Impact

The unit ships as a single breaker with screw-clamp terminals that accept conductors down to 14 AWG. No additional accessories or software are included, so the installer must supply compatible bus connections and mounting hardware.

Pre-Order Checklist

Verify that the panel accepts THHQB series bolt-on breakers and that the 60 A frame size matches the bus rating. Confirm three-phase 120/240 V AC supply, available pole space, and that the 3.3 in length, 3 in width and 2.4 in depth fit the enclosure.

Questions about this item

Will the screw-clamp terminals on this 30 A breaker need periodic re-torquing after installation?

The screw-clamp terminals accept wire down to 14 AWG and are designed to maintain clamping force; re-torquing is only required if a visual inspection shows a loose connection.

What is the maximum available interrupting rating that limits fault-current handling on this THHQB unit?

The breaker carries a 22 kA AIR rating at 120/240 V AC, so fault currents above that level would exceed its interrupting capacity.

How much heat does the 3-pole frame dissipate when running continuously at 30 A in a load-center enclosure?

The 60 A frame size and bolt-on mounting are rated for continuous 30 A operation; normal temperature rise stays within UL limits for enclosed load-center installations.
