Product FAQs
5 answersWhich panelboards are compatible with the TEYH3025B circuit breaker?
This breaker is designed specifically for bolt-on installation in GE A-Series lighting panelboards. It is not compatible with standard residential load centers or plug-on Q-Line panels.
What differentiates the TEYH series from standard TEY breakers?
The 'H' in the TEYH3025B catalog number indicates a higher interrupting capacity. While standard TEY breakers are typically rated at 14kAIC at 277/480VAC, the TEYH series provides a 35kAIC rating at the same voltage, making it suitable for commercial systems with higher available fault currents.
Can the TEYH3025B replace a TEYD3025B or TEYF3025B?
Yes, it shares the exact same physical dimensions and bolt-on mounting configuration as the TEYD and TEYF series. Upgrading to the TEYH3025B provides a higher interrupting rating while maintaining full panel compatibility.
What wire sizes are accepted by the lugs on the TEYH3025B?
The factory-installed lugs accept 14-10 AWG copper (Cu) wire or 12-10 AWG aluminum (Al) wire. Always ensure proper torque is applied during installation as specified on the breaker faceplate.
Is this 3-pole breaker suitable for DC applications?
Yes, the TEYH3025B is rated for use in DC circuits up to 250VDC, where it provides a 10kA interrupting capacity.
