Product Description:
The KT4020-00 is an AC frequency drive produced by Danaher for the NEXTDRIVE Frequency Drives series. It converts fixed-frequency mains power into a variable output that allows controllers to match induction motor speed to real-time load conditions on conveyors, pumps, or mixers used in automated plants. By varying voltage and frequency simultaneously, the unit reduces mechanical strain and improves process efficiency. The drive can support controlled acceleration and deceleration while adjusting motor operation to changing process demands.
The drive delivers a nominal output current of 20 A RMS, while its continuous output current reaches 24 A RMS, allowing the inverter to handle elevated demand without thermal derating. Upstream wiring must accommodate a maximum input current of 32 A RMS, which affects circuit breaker selection and feeder sizing. Motor terminals can supply up to 3 × 460 V, allowing connection to standard 460 V three-phase machines. The IP20 enclosure requires installation inside a closed panel while providing protection against accidental finger contact after mounting. Input terminals accept conductors up to 10 mm², and the minimum input cable cross section is 6 mm², allowing the use of standard industrial wiring. The drive does not include a keypad or brake resistor, so remote programming equipment may be required for local parameter entry, and an external braking component may be needed for rapid deceleration.
Short-term transients are managed through a peak output current of 30 A RMS and a peak overload capacity of 150%, allowing the inverter to accelerate motors or handle brief torque spikes. For longer events, the drive tolerates a continuous overload of 120%, providing additional current capacity before temperature sensors initiate current reduction. Internal switching devices dissipate 750 W as heat under rated conditions, so the enclosure must provide enough airflow to remove this thermal loss and keep semiconductor temperatures within acceptable limits. The assembly weighs 29 kg, which affects panel layout, lifting provisions, and support hardware. It is suitable for motors in the typical 10 kW class when paired with appropriate cable sizes and protective devices.
