  • Bolt-on mounting fits GE AE lighting panels directly
  • Compact 5.25 × 1 × 3.06 in frame saves panel space

GE TEY115 Circuit Breaker Specifications

The GE TEY115 is a molded case circuit breaker rated at 15 amps for single-phase systems. It operates at 277/480V AC and 125V DC with a standard thermal-magnetic trip unit. This bolt-on device fits GE AE lighting panels and provides a 14kA interrupting rating at 277V AC.

Thermal Magnetic Trip Performance

The breaker uses a fixed instantaneous trip set at 575 amps with a high amp thermal setting. Thermal-magnetic operation responds to sustained overloads and sudden short circuits without external power. The 125-amp frame size supports the 15-amp rating within the TEY series design for panelboard protection.

Bolt-On Mounting and Lug Terminals

A bolt-on mounting style secures the single-pole unit directly to the panelboard bus for a stable connection. Lug terminals accept wire connections for line and load sides. The compact profile measures 5.25 inches high, 1 inch wide, and 3.06 inches deep for standard panel installations.

Questions about this item

How do I bolt this TEY breaker onto a GE AE lighting panelboard, and which step is often missed?

Align the bolt-on feet with the panelboard mounting holes, torque the mounting bolts to spec, then insert the terminal lugs; the step most often missed is verifying the lugs are fully seated before tightening the panel cover.

What part of this 15 A breaker will need replacement after repeated fault trips?

The thermal-magnetic trip unit is calibrated for a 575 A instantaneous setting; after multiple high-current interruptions the calibrated elements can drift, so the entire breaker should be replaced rather than serviced.

At what sustained current does the 14 kA interrupting rating at 277 V become the limiting factor?

The 14 kA AIR rating at 277 V AC is the maximum prospective short-circuit current the breaker can safely interrupt; sustained loads above 15 A will trip the thermal element long before the interrupting limit is reached.
