Product FAQs
6 answersWhat panelboards are compatible with the TEYF2100 circuit breaker?
This breaker is designed for use in ABB and GE A-Series lighting panelboards. It features a bolt-on mounting base for a secure connection to the panel bus.
What is the difference between a standard TEY and the TEYF2100 breaker?
The F in the TEYF frame designates a higher interrupting capacity. While a standard 100A TEY breaker is rated for 14kAIC at 480Y/277VAC, the TEYF2100 provides an 18kAIC rating at the same voltage.
What are the recommended wire sizes and torque specifications for the TEYF2100?
The lugs accept 4 AWG to 1/0 AWG copper or aluminum wire. When terminating, tighten 4 AWG wire to 45 in-lbs, and 3 AWG to 1/0 AWG wire to 50 in-lbs.
Can the TEYF2100 be used in place of TEYD, TEYH, or TEYL breakers?
Yes, the TEYF2100 shares the same physical footprint and can serve as an alternative to TEYD2100B, TEYH2100B, and TEYL2100B models, provided the 18kAIC fault rating meets your system requirements.
What does the LI trip function on this breaker indicate?
The LI designation means the thermal-magnetic trip unit includes both Long-Time (thermal) protection against sustained overloads and Instantaneous (magnetic) protection against short circuits. Both settings are fixed on this model.
Can this breaker be used in DC applications?
Yes, the TEYF2100 is rated for up to 250VDC with a 10kAIC interrupting rating, making it suitable for specific ungrounded battery or direct current systems.
