GE THQB2170 70 A Bolt-On Breaker

The GE THQB2170 is a 70 amp, two-pole miniature circuit breaker rated for 120/240 V AC single-phase service. It mounts by bolting onto a compatible THQ frame and carries a 10 kA interrupting rating at the rated voltage. The toggle actuator provides manual on-off-reset operation.

For lighting panels and load centers needing 70

This breaker suits electricians and maintenance staff fitting or replacing a 70 A branch device in GE load centers or lighting panels that accept the THQB bolt-on series. It is not for applications requiring a DC voltage rating, a plug-in mounting style, or a frame size larger than 100 A.

10 kA interrupting rating at 120/240 V AC

The 10 kA AIR rating is the single specification that confirms the breaker can safely clear the available fault current in the panel. Verify that the system’s calculated short-circuit current does not exceed this value before installation.

Questions about this item

How much heat or noise does the THQB2170 generate when it carries a full 70 A load all day?

The breaker has no fan or moving parts, so it runs silently; normal warmth at rated current is expected but no active cooling is required.

What panel or mounting hardware must I already have to install this bolt-on, two-pole breaker?

It fits a GE load center or lighting panel with a 100 A frame and accepts 8 AWG to 1/0 AWG lug connections.

Will this 120/240 V AC breaker coordinate with an older 10 kA-rated panel I want to keep?

Yes — its maximum AIR rating is 10 kA at 120/240 V AC, matching panels rated for that interrupting capacity.
