131B9975
by Danfoss
The Danfoss manufactured 131B9975 is an AC micro drive assigned to the FCD 300 Micro Drives series. It corresponds to internal model code CD-302P11KT4P21H1 and is delivered without a local control panel, making it intended for remote keypad or fieldbus supervision. Danfoss lists the primary application as processing lines, so the unit regulates conveyor or mixer motors where variable speed improves throughput and energy usage. Within an automation cell the drive mounts close to the motor, reducing panel wiring and simplifying maintenance.
Electrical capacity centers on a nominal output of 11.0 kW, adequate for small to mid-range induction motors used on pumps, agitators, or compact extruders. The three-phase input window spans 380 V to 480 V, allowing the same drive to operate on common low-voltage industrial mains without hardware changes. An IP21 ingress rating means the enclosure protects against fingers and vertically dripping water, so it must be installed inside a cabinet or covered area. Conducted emissions are limited to the H1 radio-frequency interference class, simplifying compliance with facility EMC rules. The unit ships without an additional protective coating, so installation sites should avoid airborne chemicals or high humidity.
The mechanical envelope follows the B1 frame code and occupies 480 mm in height, 260 mm in depth, and 242 mm in width. With a mass of 21.72 kg, the drive can be bolted to a wall or bracket without additional load-bearing structures, yet installers should allow adequate clearance for cooling fins. These dimensions support side-by-side mounting inside processing skids, and the weight favors single-person handling with proper support tools. Adhering to the stated footprint ensures cable bend radii are maintained and that airflow around neighboring equipment is unobstructed.
