GE TEY370 70A 3-Pole 277/480V Circuit Breaker

SKU CH-QHG2-EY3RW

A 70 A, three-pole molded-case breaker rated 277/480 V AC with a 14 kA interrupting capacity and thermal-magnetic trip for GE AE lighting panels

  • 70 A rating protects three-phase loads up to 277/480 V AC
  • 14 kA interrupting capacity clears faults safely at full voltage
  • Thermal-magnetic trip responds to overloads and short circuits without adjustment
  • Bolt-on mounting fits GE AE lighting panels directly
  • Compact 5.25 in height saves panelboard space

Application & Purpose

The GE TEY370 is a 70 A, three-pole molded case circuit breaker rated for 277/480 V AC and 250 V DC. It provides standard thermal-magnetic overcurrent protection for three-phase panels in commercial and industrial electrical systems.

Build & Connections

The breaker uses a bolt-on panelboard mounting style compatible with GE AE lighting panels and a 125 A frame size. Lug terminals accept cable connections, while the fixed instantaneous trip and single high-amp setting of 250 A define its response curve.

Protection Limits

Maximum interrupting capacity is 14 kA at the rated AC voltage, setting the upper fault-current boundary the device can safely clear. Operation beyond this prospective short-circuit level or outside the stated voltage ratings is not supported by this model.

Questions about this item

What is the 277/480V AC interrupting rating of the TEY370?

The breaker carries a 14 kA maximum AIR rating at 277/480V AC, which caps the fault current it can safely clear on that voltage.

What panel space and mounting style does the 70 A TEY frame require?

It uses a bolt-on mounting style for GE AE lighting panels and measures 5.25 in high, 3 in wide and 3.06 in deep.

How is the TEY370 installed, and what step is commonly missed?

Bolt the breaker onto the panelboard bus, then torque the lug terminals to the specified value; the torque step is often overlooked.
