Product Description:
The FC-301P37KT4131B6462 is a variable frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. It modulates the frequency and voltage of three-phase power to control induction motor operation. Motors can accelerate, decelerate, or maintain a fixed speed according to PLC commands in material-handling systems, pumping applications, and general process lines.
The inverter section is rated at 37 kW (50 HP), indicating the continuous electrical power it can deliver to the motor terminals. It accepts a supply range of 380 to 480 VAC, which is compatible with common 400 V industrial grids, and its full-load efficiency reaches 0.98, limiting heat generation and reducing energy drawn from the power supply. An enclosure rated at IP55 / NEMA Type 12 protects the electronics from dust and low-pressure water jets, allowing cabinet-free wall mounting in suitable production areas. During steady operation with a supply between 441 and 500 V, the drive delivers 65 A of output current, while its expected internal power loss is 697 W. These values help determine the airflow and heat dissipation requirements for the installation area.
The chassis uses frame size C1 and measures 310 mm deep, with a mounting plate footprint of 680 mm by 308 mm. An included dynamic braking circuit allows the built-in chopper to dissipate regenerated energy during rapid deceleration instead of returning it to the power grid. Conducted emissions meet RFI class A2, supporting installation on unrestricted industrial supply networks. Upstream protection should use a gG-100 A fuse for appropriate short-circuit and overload coordination. Continuous input demand is 59 A and can rise to 88.5 A during short transients. The intermittent output current reaches 97.5 A when additional acceleration torque is required.
