Danfoss 131X6100 at a glance
The Danfoss 131X6100 is an 11 kW / 15 HP VLT HVAC Drive FC 102 for 3 × 380–480 V AC supplies, made for the fans, pumps and compressors in building services. It is a frame B1, IP55 / UL Type 12 unit, built for wall mounting in plant rooms without a separate enclosure.
This configuration has RFI class A1/B (C1) with reduced motor cable length, no brake chopper, and a graphical LCP 102 control panel. The full type code is decoded alongside the FAQs.
Sizing and installation
- Continuous output current: 24 A / 21 A. Size the drive on the motor nameplate current at your actual supply voltage.
- Intermittent (overload) current: 26.4 A / 23.1 A — the normal-overload rating that suits variable-torque fan and pump loads.
- Enclosure: IP55 / UL Type 12 — built for wall mounting in plant rooms without a separate enclosure.
- EMC: RFI class A1/B (C1) is met only with a reduced screened motor cable length. Check the maximum length for this frame in the Danfoss FC 102 Design Guide (Technical Documents tab); for longer runs, ask us about an H2 (A2/C3) variant.
FC 102 features for HVAC
- Built-in RS-485 protocols: Danfoss FC, Modbus RTU, BACnet MS/TP, Metasys N2 and FLN Apogee — connects to most building management systems without an option card.
- Fire Mode keeps the drive running during an emergency, for example to keep smoke-extract fans turning.
- Automatic Energy Optimisation (AEO) cuts motor losses at part load — Danfoss quotes a further 5–15% saving.
- Pump and fan functions: sleep mode, dry-pump, end-of-curve and broken-belt detection, plus a built-in cascade controller for pump sets.
- Built-in DC coils limit mains harmonics (EN 61000-3-12).
- Smart Logic Controller for simple sequencing without a PLC.
Where the energy saving comes from
Centrifugal fans and pumps follow the affinity laws: absorbed power falls with the cube of speed. Running at 80% speed needs roughly half the power of full speed (0.8³ ≈ 0.51, before motor and drive losses) — which is why speed control pays back faster on fans and pumps than almost any other load.

Frequently asked questions
What is the maximum motor cable length with this RFI filter?
The 131X6100 has the H3 filter: RFI class A1/B (C1) with a reduced motor cable length. The exact limit for this frame is in the Danfoss VLT HVAC Drive FC 102 Design Guide (see Technical Documents). If your screened cable run is longer, contact us and we will suggest an alternative.
Which communication protocols are built in?
Danfoss FC, Modbus RTU, BACnet MS/TP, Metasys N2 and FLN Apogee over the built-in RS-485 port. This unit has no fieldbus option card fitted, so PROFIBUS, PROFINET, EtherNet/IP or BACnet/IP would need an MCA option card.
What output current does it deliver at 400 V and at 480 V?
Continuous output current is 24 A / 21 A; intermittent current is 26.4 A / 23.1 A. Always size on the motor nameplate current at your supply voltage.
Can this drive be wall mounted without a panel?
Yes. The IP55 / UL Type 12 enclosure is designed for direct mounting.
