FC-051P15KT4E20H3BXCXXXSXXX by Danfoss

The FC-051P15KT4E20H3BXCXXXSXXX is a compact AC motor controller manufactured by Danfoss for the VLT FC 51 Micro Drives series. As a variable-speed drive, it is intended for general industrial automation where a small footprint and straightforward setup are important, such as conveyor, fan, and pump applications. It adjusts motor speed to match process demand, which helps support smoother operation in equipment that does not require a large drive platform. Its compact housing also makes it suitable for cabinet installations where available panel space is limited.

This model delivers a continuous output of 15 kW, which corresponds to 20 HP, so it can operate medium-sized induction motors in typical industrial service. It accepts a supply between 380-480 VAC on a three-phase network, matching common plant power systems. The chassis has an IP20 protection level, so it is intended for installation inside an enclosure where dust or moisture exposure can be controlled. Standard cable entries are provided for typical wiring layouts, and the unit does not include a factory-installed mains disconnect, so external isolation must be provided elsewhere in the installation. The drive is supplied without a local control panel, so parameter settings can be entered with a PC tool or an optional detachable keypad.

Electromagnetic compliance is supported by the integrated RFI Class A1/B filter, which reduces conducted noise on the line side. For controlled stopping or energy handling during deceleration, the unit includes a built-in brake chopper. Long-term durability in dusty or humid control cabinets is supported by a coated PCB, which helps protect copper traces from corrosion. This protective finish is useful in enclosed industrial panels where airborne contaminants or condensation can shorten the service life of uncoated electronics.
