Danfoss 132H0717 FC 103 Refrigeration Drive 11 kW IP66

FC 103 11 kW in IP66: a refrigeration drive for rooftop and machine-room duty

Danfoss 132H0717 is an FC-103P11KT4P66H2XGX drive. The VLT Refrigeration Drive FC 103 is the Danfoss variant for compressors, condenser fans and evaporator fans, and this 11 kW (15 HP) code carries a P66 housing: IP66 / NEMA 4X on a backplate. That rating allows the washdown of cold-store plants and installation on a roof where rain and dust are a fact of life.

The store lists a power loss of 278 W and dimensions of 494 x 243 x 261 mm (H x W x D). Net weight is 20.82 kg. The code also includes a B option, the MCB-109 I/O board with real-time-clock back-up, which adds analogue I/O and keeps the clock running during a power outage.

Technical specifications

Refrigeration-specific points

The operating instructions for the FC 103 list sleep mode, a smart logic controller and a parameter group for the application. Real-time clock functions are useful for scheduled set-point changes such as night set-back or defrost-linked fan speeds, and the MCB-109 board provides the back-up battery for that clock.

Using a variable-speed drive on a compressor changes the oil return and the lubrication conditions, so check the compressor manufacturer’s minimum speed before enabling a wide speed range.

Mounting and EMC

The H2 RFI filter is class A2, which suits an industrial site but not a residential or light-commercial site. The enclosure is a B1 frame at 494 x 243 x 261 mm. Gland the cables properly, otherwise the IP66 rating is lost at the cable entries; the standard cable entries are used in this code.

Remember the clearances for cooling above and below the heat sink, and avoid direct sun on the housing in the Gulf summer. The guide lists the derating values for temperature and altitude.

Cold-store and rooftop plants often hold a spare drive for each compressor motor size, because a failed drive can stop a whole refrigeration circuit. Keep the parameter backup and the clock settings of the MCB-109 board in the maintenance file. If the plant uses several FC 103 sizes, ask us to quote the family together so that the options and the software versions are consistent across the order.

Projects that use 132H0717 often need related parts from the same manufacturer, such as connectors, mounting parts or spare kits. Mention them in the same enquiry so that compatibility can be checked together rather than discovered on site, when a missing part stops the work.
