Product FAQs
5 answersWhich panelboards accept the TEY320 circuit breaker?
This bolt-on miniature circuit breaker is specifically designed for installation in GE A-Series lighting panelboards.
Are there higher interrupting rating alternatives to the standard TEY320?
Yes. The standard TEY320 provides 14kAIC at 480/277VAC. If your fault current study requires a higher rating, the exact same physical footprint is available in the TEYF320 (18kAIC), TEYD320 (25kAIC), TEYH320 (35kAIC), and TEYL320 (65kAIC) series.
Is the TEY320 suitable for HVAC and refrigeration equipment?
Yes, the entire GE TEY family of circuit breakers carries a UL HACR rating, ensuring safe operation for heating, air conditioning, and refrigeration systems.
Does this breaker carry a rating for commercial lighting loads?
Yes. TEY series breakers rated 50 amps and below, including this 20-amp model, are UL listed for high-intensity discharge (HID) lighting applications commonly found in commercial facilities.
Can the TEY320 be individually mounted outside of an A-Series panelboard?
Yes. While typically bolted onto a panelboard bus, it can be adapted for unit-mount or lug-to-lug surface mounting by installing it with the GE TEY3B bolt-on mounting base accessory.
