ABB / General Electric TEY260 Miniature Circuit Breaker

The TEY260 is designed exclusively for bolt-on installation in GE A-Series lighting panelboards. It is not compatible with standard GE PowerMark load centers, which require plug-on or different bolt-on frame types.

Yes. ABB acquired GE Industrial Solutions and continues to manufacture the TEY series under the ABB and GE brands. The TEY260 catalog number represents the exact same physical and electrical component regardless of which brand name is printed on the label.

The factory-installed lugs require specific torque settings based on the wire gauge used. Tighten 10 AWG wire to 35 in-lb, 8 AWG to 40 in-lb, and 6 to 4 AWG wire to 45 in-lb.

A slash rating of 277/480VAC indicates the TEY260 is approved for use only in solidly grounded wye electrical systems where the line-to-ground voltage does not exceed 277V, and the line-to-line voltage does not exceed 480V. It is not rated for ungrounded or corner-grounded delta systems.

Yes, the TEY260 is thermal magnetic and carries a DC rating. It is rated to safely interrupt up to 10kAIC at 250VDC, making it suitable for specific solar, battery, or industrial control circuits requiring DC protection.

The factory lugs on the TEY260 accept both copper and aluminum conductors ranging from 10 AWG up to 4 AWG.

No, the standard TEY260 comes with fixed thermal and magnetic trip units and does not include factory-installed internal accessories. Shunt trips, bell alarms, or auxiliary switches must be ordered as specific accessory variants if required for your control system.

The TEY260 is primarily utilized as a branch or feeder breaker. However, it can function as a main breaker in smaller A-Series panelboards if the panel interior and bus configuration are specifically designed to accept a TEY frame as a back-fed main.

When installed in a GE A-Series panelboard, the breaker bolts directly to the interior bus. If used in a standalone or custom control panel application, a separate bolt-on mounting base accessory is required to utilize it as a lug-to-lug breaker.
