ABB / General Electric THQD22150WL Molded Case Circuit Breaker

The "WL" suffix means the breaker is supplied with factory-installed line and load lugs. This configures it as a feed-thru, unit-mount breaker rather than a bus-connected model.

The primary difference is the short circuit interrupting capacity. The TQD series has a standard rating of 10 kAIC at 240V, whereas the THQD series features a higher 22 kAIC rating. Both share the same physical Q-Line frame size.

Yes, this breaker is suitable for reverse feed applications. The line and load connections can be swapped without compromising the thermal-magnetic protective functions.

This breaker can be installed in GE Q-Line standalone enclosures designed for TQD and THQD frames up to 225A, such as the NEMA 3R rated TQD225NR for outdoor applications.

As a unit-mount, feed-thru breaker, it does not plug or bolt onto a traditional panelboard bus. It is individually mounted to a backpan or enclosure and hardwired directly on both the line and load sides.

Yes, the included lugs are dual-rated for both copper and aluminum (Cu/Al) conductors, accepting wire sizes from 4 AWG up to 300 kcmil.

It features a fixed, non-interchangeable thermal-magnetic trip unit with common trip functionality. This ensures both poles open simultaneously during long-time overloads or instantaneous short circuits.

Yes, GE THQD series molded case circuit breakers are HACR rated, making them suitable for protecting heating, air conditioning, and refrigeration equipment circuits.
