GE TEY330 Molded Case Circuit Breaker
The GE TEY330 is a 30 A molded case circuit breaker designed for three-phase AC systems rated at 277/480 V. It uses a thermal-magnetic trip mechanism with a fixed instantaneous setting and a high amp trip point of 575 A. The unit carries a maximum interrupting rating of 14 kA at the rated AC voltage and is built on a 125 A frame size for bolt-on mounting in compatible panelboards.
Compatibility checks before ordering
Verify that the panelboard accepts bolt-on style breakers and is listed for use with GE AE lighting panels. Confirm the system voltage matches the 277/480 V AC rating or the 250 V DC rating if applied to DC circuits. Ensure the available fault current does not exceed the 14 kA interrupting capacity and that the 3-pole ABC phase connection suits the installation wiring layout.
Thermals noise and power draw
The thermal-magnetic trip unit responds to sustained overloads through its thermal element and to short circuits via the fixed magnetic trip set at 575 A. Normal operation produces no audible fan noise because the device relies on passive convection within the enclosure. Physical dimensions are 5.25 in height, 3 in width and 3.06 in depth, which determine the required panelboard space and clearances for heat dissipation.

Questions about this item
Does the GE TEY330 breaker come with mounting hardware or must lugs be purchased separately?
The breaker uses bolt-on panelboard mounting and includes a terminal connection lug; no extra lugs are required for standard installation.
When should I choose the 30 A version versus other TEY frame sizes?
Select the 30 A model when branch-circuit protection at 30 amps is specified; the TEY frame supports up to 125 A, so higher ratings need a larger trip unit.
What does the 14 kA AIR rating mean for a live panel?
The breaker can safely interrupt up to 14 kA of fault current at 277/480 V AC, so the panel’s available short-circuit current must not exceed that value.
