Product images are representative only. Actual product may vary.
The GE TFJ236Y225 is a 225A, 3-pole F-frame non-automatic molded case switch with bolt-on mounting, rated 600VAC for GE A-Series and legacy J-Line panelboards.
This is a disconnect, not a breaker. The "Y" in the catalog number designates a non-automatic device: it has the mechanical switching capability and short-circuit withstand rating of a molded case breaker, but no trip unit, so it will not open on an overcurrent. That is exactly what you want at a main distribution point where overcurrent protection is provided upstream and the local requirement is a lockable means of isolation for service and maintenance. It withstands 22kA at 480VAC without damage, accepts conductors from #4 AWG to 300 kcmil, and mounts as an exact substitute for the TFK236Y225. Field-installable shunt trips and auxiliary switches allow remote opening where required.

Frequently Asked Questions
Does the TFJ236Y225 provide overcurrent protection?
No. The Y designation means it is non-automatic — a molded case switch with no trip unit. It will not open on an overload or short circuit. Overcurrent protection must be provided by an upstream device.
Why use a molded case switch instead of a breaker?
When the code or the design requires a local disconnecting means but overcurrent protection already exists upstream, a molded case switch provides lockable isolation without adding an unnecessary and potentially miscoordinated trip point to the system.
What does the 22kA rating mean if it does not trip?
It is a withstand and closing rating: the switch can carry and interrupt through a 22kA fault at 480VAC without failing, while the upstream protective device does the clearing.
What older GE part does the TFJ236Y225 replace?
It is an exact substitute for the TFK236Y225, using the same bolt-on F-frame footprint.
What wire sizes does the TFJ236Y225 accept?
#4 AWG through 300 kcmil copper or aluminum conductors.
Can the TFJ236Y225 be opened remotely?
Yes, with a field-installed shunt trip accessory. Auxiliary switches and undervoltage releases are also available.
Which panelboards accept this switch?
GE A-Series panelboards and legacy J-Line panelboards using bolt-on mounting.
Is the TFJ236Y225 UL listed?
Yes. It is UL 489 listed as a molded case switch and CSA certified to C22.2 No. 5.
