Danfoss 131B4229 FC 102 HVAC Drive 4 kW 380-480 V IP55
Description
FC 102 4 kW in IP55: a wall-mounted HVAC drive that needs no cabinet
Danfoss 131B4229 is a VLT HVAC Drive FC 102 with the type code FC-102P4K0T4E55H2XGX. It is rated 4.0 kW (5 HP) on 380 to 480 V three-phase mains and sits in the A5 frame, an IP55-class housing. Because the enclosure is IP55 / Type 12, the drive can be mounted directly on a plant-room wall, a fan-deck or a pump base without a panel.
The store lists a continuous output of 10 A and an intermittent 60-second value of 11 A at normal overload, plus a power loss of 124 W. Those numbers are what you need to size the motor cable, the fuses and the heat that stays in the room.

Typical duty and design considerations
The FC 102 is the Danfoss drive for air handling units, supply and extract fans, chilled-water pumps and cooling-tower fans. The design guide for the series, 1.1 to 90 kW in enclosure sizes A to C, treats it as a single platform with a graphical control panel, built-in RFI filtering and Safe Torque Off in the safety description.
At 4 kW the code suits a small AHU fan or a booster pump. The drive weighs 10.59 kg net, 420 mm high and 200 mm deep, so two screws on a wall frame are enough. Leave the free air space around the heat sink that the guide prescribes, particularly in a hot Gulf plant room.
What the type code tells you
Each field of FC-102P4K0T4E55H2XGXXXXSXXXXAXBXCXXXXDX has a meaning. P4K0 is the power size, T4 the 380 to 480 V three-phase supply, E55 the IP55 housing, H2 the RFI filter version printed in the store as an RFI filter, and G the graphical local control panel. The remaining X positions mean no brake chopper, no coated boards, no mains option, standard cable entries and no A, B, C or D option cards.
That means this code is the base configuration. If you need a brake chopper, coated boards for a corrosive site or a fieldbus card, a different code number is required; quote the full type code of the unit you want to replace.
Please treat the values on this page as a summary of the manufacturer data and verify them against the attached document for your application. If anything in your enquiry does not match the page, tell us and we will check it before a quotation is issued for 131B4229.
Ordering notes
Please confirm the supply voltage and frequency, motor current, ambient temperature and required enclosure before ordering. Seven Star LLC is an independent supplier in Muscat and can quote 131B4229 against your data.

About brand
Danfoss is the Danish engineering group that makes refrigeration and air-conditioning controls, heating components, variable speed drives and mobile hydraulics. Mads Clausen founded it on 1 September 1933 at his parents' farm in Nordborg on the island of Als, after making his first refrigeration expansion valve in 1932. Nordborg is still the group's headquarters, and Danfoss remains controlled by the Clausen family through the Bitten & Mads Clausen Foundation.
Danfoss company profile
| Founded | 1 September 1933, Nordborg, Denmark, by Mads Clausen (1905–1966) |
|---|---|
| First product | Thermostatic expansion valve for refrigeration |
| Headquarters | Nordborg, Denmark |
| Ownership | Private; majority controlled by the Bitten & Mads Clausen Foundation and the Clausen family |
| Size | About 42,000 employees (2023) |
| Business segments | Danfoss Climate Solutions (refrigeration, air conditioning and heating), Danfoss Drives (VLT and VACON frequency converters, soft starters), Danfoss Power Solutions (mobile and industrial hydraulics) |
| Brands in the group | VLT, VACON, Eaton Hydraulics (bought 2021), Ikusi radio remote controls |
Milestones
- 1932–1933: First expansion valve; the company is founded in Nordborg.
- 1939: 26 employees. By the 10th anniversary in 1943 the company has 179.
- 1950s: Rapid growth turns Nordborg into a Danfoss town with housing and schools for its workforce.
- 1968: Danfoss launches its VLT frequency converter, one of the first mass-produced AC drives.
- 2014: Acquisition of the Finnish drives maker Vacon, now the VACON brand.
- 2021: Acquisition of Eaton's hydraulics business.
Choosing Danfoss products
For solenoid valves, check the operating principle. A direct-operated valve such as EV210B opens even at 0 bar differential pressure. A servo-operated valve such as EV220B needs a minimum differential (typically about 0.3 bar) to open, while an assisted-lift valve such as EV250B works from 0 bar. Coils are ordered separately, so the voltage on the coil (for example 230 V AC or 24 V DC) must match the control circuit. For drives, the VLT family is split by application: FC 51 Micro Drive for small machines, FC 102 HVAC Drive for fans and pumps in buildings, FC 202 AQUA Drive for water, and FC 302 AutomationDrive for demanding industrial duty.
Where Danfoss products are used
In Oman and the GCC, Danfoss drives run pumps, fans and compressors in district cooling plants, water and wastewater stations, desalination and building HVAC. Danfoss pressure switches, transmitters and solenoid valves are built into chillers, refrigeration plants, boilers and hydraulic systems, and AB-QM valves balance chilled-water circuits in large buildings.

Ordering Danfoss products: what we need
Send the Danfoss code number from the label (for example 032U7115 or 131B0149) or the full drive type code (FC-302P3K0T5...). For drives, add the motor power, supply voltage and any fieldbus option. For valves, add the size, connection, medium and coil voltage. For pressure switches and transmitters, add the range, output and pressure connection.
