Product FAQs
9 answersWhat panelboards are compatible with the TEY330ST12?
This breaker is specifically designed to bolt directly into GE A-Series panelboards. It is a one-inch wide per pole device intended for grounded 480Y/277 VAC systems.
What does the ST12 suffix mean on this specific breaker?
The ST12 designation indicates that the breaker comes with a factory-installed shunt trip accessory. This allows for remote tripping of the breaker using a 120 to 277 VAC control voltage.
How does the interrupting capacity vary based on the system voltage?
The breaker provides a 14kAIC rating on 480Y/277VAC systems. However, the interrupting capacity increases to 65kAIC on 120VAC or 240VAC systems, and it is rated for 10kAIC when applied to 250VDC circuits.
Why might my TEY330ST12 breaker arrive with ABB branding instead of GE?
ABB acquired GE Industrial Solutions in 2018. Because of this transition, the breaker may feature either ABB or GE branding depending on when it was manufactured, but the physical dimensions and technical specifications remain exactly the same.
Can this breaker be used to protect HVAC and lighting circuits?
Yes, this model is both HACR rated for heating, air conditioning, and refrigeration equipment, and HID rated for high-intensity discharge lighting loads.
What type of protection does the LI trip function provide?
The LI designation stands for Long-Time and Instantaneous trip functions. The thermal long-time element protects against sustained overloads, while the magnetic instantaneous element trips the breaker immediately during a short circuit.
Are the trip settings adjustable on the TEY330ST12?
No, this breaker features a non-interchangeable trip unit with fixed thermal and fixed magnetic settings.
What wire sizes are accepted by the terminals on this breaker?
The factory-installed lugs accept 10 AWG to 4 AWG wire and are rated for both copper and aluminum conductors. Ensure proper torque is applied during installation to maintain a secure connection.
Does this breaker require a separate mounting base for installation?
When installed in a standard GE A-Series panelboard, it bolts directly to the bus. However, if used in standalone lug-to-lug applications, a separate TEY3B mounting base is required.
