GE TKM3F1200 – Three-Phase Terminal Kit for 1200 Amp Applications

In stock

Product Introduction:
The TKM3F1200 is a heavy-duty terminal kit designed for GE electrical distribution and power control equipment. The “TKM” designation stands for Terminal Kit Mounting, indicating it is a wiring termination accessory. The “3F” indicates it is designed for three-phase power applications. The “1200” specifies that it is rated for 1200 Amperes of continuous current. This terminal kit provides the physical connection points for large power cables (typically 500 kcmil to 750 kcmil copper or equivalent aluminum) to be terminated onto bus bars, circuit breakers, contactors, or disconnects. It is a critical component in high-power electrical switchgear, motor control centers (MCCs), and distribution panels.
