ABB / General Electric THQD22225 Molded Case Circuit Breaker

The primary difference is the short circuit interrupting rating. The TQD22225 is rated for 10kAIC at 240V, while the THQD22225 provides a higher interrupting capacity of 22kAIC at 240V. Both share the same physical frame size and mounting footprint.

Following ABB's acquisition of GE Industrial Solutions, this breaker may feature either GE or ABB branding. The form, fit, function, and UL listings remain identical regardless of the logo printed on the label.

This is a unit mount, feed-thru breaker. It bolts directly to the chassis of GE A-Series or Spectra Series panelboards, or to the backpan of an individual enclosure, rather than plugging onto a busbar.

Yes, this breaker supports reverse feed applications. This makes it suitable for use as a main breaker or in generator back-feed setups where permitted by local electrical codes.

Yes, this breaker is HACR rated. It is approved for use with heating, air conditioning, and refrigeration equipment that requires a 225A overcurrent protection device.

No, the THQD22225 features a non-interchangeable trip unit with fixed thermal and fixed magnetic settings for long-time and instantaneous protection.

Yes, it includes an internal common trip mechanism. If an overcurrent or short circuit fault occurs on either of the two poles, both poles will trip simultaneously to safely disconnect all ungrounded conductors.

The included line and load lugs accept 4 AWG to 300 kcmil copper or aluminum wire. When terminating, ensure conductors are sized according to the 75C ampacity column in the NEC for a 225A circuit.
