ABB / General Electric TQD32150WL Molded Case Circuit Breaker

This breaker is designed for use in GE and ABB A-Series panelboards, GE individual enclosures, and compatible switchboards.

The WL suffix indicates that the circuit breaker comes complete with factory-installed copper and aluminum line and load lugs, specifically the TCAL25 lug kit.

Both are 150A, 3-pole Q-Line circuit breakers with identical physical dimensions. The primary difference is their short circuit interrupting capacity. The TQD is rated at 10kAIC at 240VAC, while the THQD is a high-interrupting version rated at 22kAIC at 240VAC.

If you are installing this breaker in a GE or ABB A-Series II panelboard with specified space mounting, a separate mounting kit like the BASPPTQD3PGE is required to connect to the existing bus provisions.

Yes. TQD series thermal magnetic circuit breakers do not have line and load specific internal mechanisms, making them suitable for reverse feed wiring.

No. The TQD32150WL features a fixed thermal and fixed magnetic trip unit. It provides long-time and instantaneous protection but cannot be adjusted in the field.

ABB acquired GE Industrial Solutions. Depending on the production batch, this Q-Line breaker may feature ABB labels, GE labels, or dual branding, but the form, fit, and function remain identical.

For main breaker applications in newer panelboards, ABB has transitioned the TQD frame to the FORMULA A2 and Tmax XT series, such as the A2A150TW. Installing these newer frames in older enclosures usually requires a retrofit kit.

Yes. This circuit breaker is HACR rated, meaning it is approved for safely protecting heating, air conditioning, and refrigeration equipment circuits.

No. Like most standard molded case circuit breakers, the TQD32150WL is rated for 80 percent continuous load unless it is housed in an enclosure that is explicitly listed for 100 percent operation.
