Product FAQs
8 answersWhat panelboards are compatible with the TEYL2020B?
The TEYL2020B is designed specifically for use in GE A-Series lighting panelboards. It utilizes a bolt-on connection to secure directly to the panel bus.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions in 2018. TEYL series breakers are now manufactured by ABB but retain the original GE branding and part numbers, making them direct replacements for existing GE TEYL2020B installations.
What does the L in the TEYL2020B catalog number indicate?
In the GE TEY frame family, the L designates a high interrupting capacity. The TEYL2020B is fully rated to safely interrupt up to 65kA at 480V or 277V, offering higher fault protection than standard TEY, TEYD, or TEYH variants.
Can the TEYL2020B be used in DC voltage systems?
Yes, this thermal-magnetic breaker is rated for DC applications. It carries an interrupting rating of 42kA at 125VDC and 20kA at 250VDC.
What wire sizes are accepted by the lugs on the TEYL2020B?
The factory-installed load lugs on this 20A breaker accept 14-10 AWG copper wire or 12-10 AWG aluminum wire.
Can I replace a standard TEY or TEYH breaker with a TEYL2020B?
Yes, the TEYL2020B shares the same physical dimensions and bolt-on mounting configuration as other TEY frame breakers. It can be used as a direct replacement or upgrade when a higher 65kA interrupting rating is required in an A-Series panelboard.
Does the TEYL2020B mount onto a standard DIN rail?
No, the TEYL2020B is a bolt-on molded case circuit breaker designed exclusively for GE A-Series panelboards. It does not support DIN rail mounting.
Does this breaker provide arc fault or ground fault protection?
No, the TEYL2020B features standard thermal-magnetic trip technology with fixed long-time and instantaneous functions for overload and short-circuit protection. It does not include built-in AFCI or GFCI capabilities.
