GE Bolt-On Breaker 50 A 277/480 V
This GE TEY250 is a two-pole molded-case circuit breaker rated for 50 amps at 277/480 volts AC with a 14 kA interrupting rating. It uses a bolt-on mounting style for GE AE lighting panels and features a thermal-magnetic trip mechanism with a fixed instantaneous setting. The frame size is 125 A and the high amp trip setting is 250 A. A lug terminal connection accepts conductors for standard panel wiring.
Suited for GE AE panels needing 50 A protection
Electricians wiring GE AE lighting panelboards will find this breaker matches the required bolt-on footprint and voltage rating. It is not suitable for panels that accept only plug-on breakers or for systems requiring a higher interrupting capacity than 14 kA at 277/480 V AC. Buyers needing a different amperage, pole count, or DC-only rating should select another model. The single-phase connection and Any phase configuration limit use to compatible panel layouts.
Bolt-on install in GE AE panelboards
Installation consists of aligning the breaker with the panelboard bus stabs and securing it with the mounting bolt, then tightening the lug terminals to the specified torque. The fixed instantaneous trip means no field adjustment is possible, so coordination studies must use the published 250 A high amp setting. Common issues include mismatched panel series, incorrect lug torque, and attempting to mount in non-GE or plug-on style enclosures.

Questions about this item
Does the buyer need a GE AE lighting panel with a bolt-on mounting rail to install this breaker?
Yes, the TEY250 is designed for bolt-on mounting in GE AE lighting panels and requires a compatible panel rail and bus connection.
Will this 50 A, 2-pole breaker coordinate with an existing 125 A frame TEY main breaker in the same panel?
The 50 A thermal-magnetic trip unit operates within the 125 A TEY frame size, allowing selective coordination when installed downstream of a 125 A TEY main breaker.
How can the installer verify the breaker trips correctly after wiring it to a 277/480 V AC circuit?
Apply rated current to confirm the thermal element opens on sustained overload and the fixed instantaneous trip operates at 250 A, observing the handle move to the tripped position.
