Product FAQs
6 answersWhat panelboards are compatible with the TEYH3070B circuit breaker?
The TEYH3070B is specifically designed for use in GE A-Series lighting panelboards. It features a bolt-on mounting style that connects directly to the panelboard bus for a secure installation.
What does the H in the TEYH3070B catalog number indicate?
The H designates this as the high-interrupting capacity version of the TEY frame. It provides a 35kAIC rating at 480/277VAC, compared to the standard TEY frame which is rated at 14kAIC.
Can I use the TEYH3070B to replace a standard TEY3070B?
Yes, the TEYH3070B shares the exact same physical dimensions and mounting footprint as the standard TEY3070B. It can be used as a direct replacement while offering a higher short-circuit interrupting rating.
What wire sizes are accepted by the lugs on the TEYH3070B?
The factory-installed lugs accept 4 AWG to 1/0 AWG copper or aluminum conductors. Always ensure connections are torqued to the manufacturer specifications printed directly on the breaker face.
Is the TEYH3070B suitable for DC voltage applications?
Yes, this breaker is rated for use in DC circuits up to 250VDC with an interrupting capacity of 10kAIC. Ensure your wiring configuration complies with GE guidelines for DC load applications.
How does the TEYH3070B mount into the panelboard?
This is a bolt-on miniature circuit breaker. It secures directly to the busbar of the panelboard using captive hardware, providing a highly reliable connection that prevents shifting under heavy electrical loads.
