Circuit breaker for three-phase panels
The GE TEY315 is a 15 A molded-case circuit breaker built for three-phase 277/480 V AC panels and rated for 250 V DC. It carries a 14 kA interrupting rating at 277/480 V AC and fits GE AE lighting panelboards using a bolt-on mounting style. The frame size is 125 A and the fixed instantaneous trip is set at 575 A.
Thermal-magnetic trip with lug terminals
A thermal-magnetic trip unit provides overload and short-circuit protection without adjustment. The fixed instantaneous setting means the breaker opens at 575 A without user calibration. Lug terminals accept standard conductor connections, simplifying wiring in the panel.
Bolt-on mounting for panelboard installation
The breaker measures 5.25 in high, 3 in wide and 3.06 in deep, matching the TEY series footprint for GE AE lighting panels. Bolt-on mounting secures the device directly to the panelboard bus, reducing movement during vibration. Three-pole ABC phase connection covers balanced three-phase loads in commercial and light-industrial distribution.

Questions about this item
Will the bolt-on lug terminals need periodic re-torquing after installation?
The bolt-on panelboard mounting and lug terminals should be checked for proper torque at initial installation and after the first load cycle; no scheduled re-torquing interval is published by GE.
What stops the breaker from carrying more than its rated current continuously?
The thermal-magnetic trip unit is calibrated for a 15 A continuous rating with a fixed instantaneous pickup at 575 A; the 125 A frame size defines the maximum interrupting capacity of 14 kA at 277/480 V AC.
How much heat does the breaker add to a fully loaded lighting panel running all day?
At 15 A the thermal element dissipates only a few watts, so temperature rise inside a GE AE lighting panel stays well within the 125 A frame design limits during continuous operation.
