Product identity
The GE TEY320 is a 20 A three-pole molded case circuit breaker designed for bolt-on installation in GE AE lighting panels. It suits electricians and facility managers who need standard thermal-magnetic protection on 277/480 V AC or 250 V DC three-phase circuits.
Accessory impact
The breaker ships with a terminal connection lug so conductors can be landed directly without separate hardware. No additional software or configuration tools are included; the fixed instantaneous trip and 575 A high-amp setting are factory-set and not field-adjustable.
Compatibility checks
Verify that the panelboard accepts bolt-on TEY frame breakers and that the available space accommodates a 5.25 in height by 3.0 in width by 3.06 in depth envelope. Confirm the system voltage does not exceed 277/480 V AC or 250 V DC and that the available fault current is within the 14 kA interrupting rating.

Questions about this item
Will the thermal-magnetic trip unit need periodic recalibration or replacement?
The trip unit is factory-sealed and not field-adjustable; if it ever fails to trip on overload or short-circuit the entire breaker must be replaced.
What is the first limit reached when the breaker runs continuously at 20 A?
The 14 kA interrupting rating at 277/480 V AC is the hard ceiling; sustained loads must stay below 20 A per pole to avoid thermal tripping.
How much heat does the three-pole assembly add to the panel when fully loaded all day?
With a 125 A frame and bolt-on lugs the breaker runs warm but stays within the panel's design temperature rise; no forced cooling is required.
