GE TEY315 Molded Case Circuit Breaker 15A 3 Pole 277/480V AC

SKU CH-ME7Q-GNR2C

Three-pole molded-case breaker rated 15 A at 277/480 V AC with 14 kA interrupting capacity and thermal-magnetic trip

  • 15 A three-pole protection for 277/480 V AC panels
  • 14 kA interrupting rating handles high fault currents
  • Thermal-magnetic trip with fixed 575 A instantaneous setting
  • Bolt-on mounting fits GE AE lighting panelboards
  • Compact 5.25 × 3 × 3.06 in frame saves panel space

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.
