ABB / General Electric TEYD2020B Miniature Circuit Breaker

The TEYD2020B is designed specifically for bolt-on installation in GE A-Series panelboards. It mounts directly to the panelboard busbars for a secure connection.

The 'D' in the TEYD series indicates its specific interrupting rating tier within the TEY frame family, offering a 25kAIC rating at 277/480VAC. This provides higher fault-clearing capacity than standard TEY breakers.

Yes, the built-in lugs on the TEYD2020B are rated for both copper and aluminum conductors. Ensure you use the correct wire sizes: 14 to 10 AWG for copper or 12 to 10 AWG for aluminum, and torque them to the manufacturer specifications printed on the breaker.

Yes, this thermal-magnetic breaker is UL listed for DC applications up to 250VDC, providing a 10kAIC interrupting capacity for DC control or distribution loads.

Following ABB's acquisition of GE Industrial Solutions, the TEYD2020B may feature either GE or ABB branding on the label. Both versions are manufactured to the same specifications and carry the same UL listings for use in A-Series panels.

This is a bolt-on miniature circuit breaker. It requires being bolted directly to the panelboard bus, providing a secure, vibration-resistant connection commonly required in commercial and industrial environments.
