What drives does it fit?
The 3G3AX-REM00K5120-IE: This resistor is designed for use with Omron 3G3MX2 and 3G3RX series VFDs, where it provides the dynamic braking resistance needed to dissipate regenerative energy from decelerating motors. For a VFD application engineer, the key fit question is whether the resistor's power rating and resistance value match the drive's braking chopper circuit — these are set by the drive's internal chopper threshold and the required deceleration duty cycle.
