Product FAQs

5 answers
What panelboards are compatible with the TEYH3020B circuit breaker?

This breaker is designed specifically for use in GE A-Series lighting panelboards.

How does the TEYH3020B mount into the panelboard?

It is a bolt-on circuit breaker that secures directly to the panelboard bus using mounting screws, ensuring a stable and reliable connection.

What is the difference between a standard TEY and the TEYH series breaker?

The H in the TEYH series indicates a higher interrupting capacity. While standard TEY breakers are rated for 14kAIC at 480Y/277VAC, the TEYH series provides a 35kAIC rating at the same voltage.

Can the TEYH3020B be used in direct current applications?

Yes, this breaker is certified for use in direct current systems up to 250VDC, providing 10kAIC of interrupting capacity for DC applications.

Can I use the TEYH3020B to replace an older standard TEY breaker?

Yes, it shares the same physical dimensions and bolt-on mounting as standard TEY breakers, allowing it to serve as a direct replacement while offering a higher interrupting capacity.
