Product FAQs
6 answersWhat does the ST12 suffix mean in the TEY315ST12 catalog number?
The ST12 suffix indicates that the breaker comes with a factory-installed shunt trip accessory. This shunt trip operates on a 120-277VAC control voltage, allowing the breaker to be opened remotely for emergency shutdowns or automated control schemes.
Can I add a shunt trip to a standard TEY315 breaker in the field?
No, internal accessories for the TEY series, including the 120-277VAC shunt trip, are factory-installed only. You must order the specific TEY315ST12 catalog number if your application requires remote tripping capabilities.
What panelboards are compatible with the TEY315ST12?
This Q-Line miniature circuit breaker is specifically designed to bolt into GE A-Series panelboards. The bolt-on connection ensures a secure, vibration-resistant installation on the panel bus.
What wire sizes are accepted by the TEY315ST12 terminals?
The factory-installed lugs accept 14-10 AWG copper conductors or 12-10 AWG aluminum conductors. Ensure proper torque is applied during installation as specified on the breaker label.
Can the TEY315ST12 be used in DC circuits?
Yes, in addition to its AC ratings, this breaker is rated for up to 250VDC with a 10kAIC interrupting capacity. This makes it suitable for certain DC control and distribution applications.
Are the trip settings on the TEY315ST12 adjustable?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time thermal and instantaneous magnetic trip functions are factory-set and cannot be adjusted by the user.
