Product FAQs
4 answersWhich panelboards are compatible with the TEYD3050B?
This bolt-on breaker is designed specifically for GE (now ABB) A-Series lighting panelboards. It is not compatible with standard residential Powermark Gold load centers or standard DIN rail systems.
How does the TEYD3050B differ from standard TEY3050 or TEYH3050 breakers?
The 'D' in the TEYD series designates an interrupting rating of 25kAIC at 277/480VAC. Standard TEY breakers are rated at 14kAIC, and TEYH breakers are rated at 35kAIC at the same voltage. All three share the same physical footprint and A-Series panel compatibility.
Does the TEYD3050B provide ground fault or arc fault protection?
No, this is a standard thermal magnetic breaker equipped with long-time and instantaneous (LI) trip functions. It does not provide GFCI, GFEP, or AFCI protection.
Is the TEYD3050B rated for 100 percent continuous load?
No, like most standard molded case circuit breakers, the TEYD3050B is rated for 80 percent continuous load. Continuous loads should not exceed 40 amps.
