Ratings and duty cycles
The 3AXD50000956654: Three duty ratings are defined: normal-use (Pn 1.5 kW / In 7.8 A), heavy-duty (PhD 1.1 kW / IhD 6.6 A), and light-overload (PlD 1.5 kW / IlD 7.5 A). The heavy-duty figure governs continuous motor load in high-torque applications; the light-overload figure matches normal-use power with slightly lower current, suggesting a different thermal model for fan/pump profiles. UL current ratings mirror the IEC values: 7.8 A normal-use, 6.6 A heavy-duty, 7.5 A light-overload. Power factor is 0.98; apparent power output is 3.1 kV·A.
Built-in BACnet protocol — no option card needed for BAS integration. Two analog inputs, one analog output. Four digital inputs, two digital outputs. No industrial Ethernet interface on this variant; communication is via serial BACnet MS/TP or similar.
Rated for 2000 m altitude, 60 °C maximum ambient. Frequency range 47.5…63 Hz covers 50/60 Hz grids. Sound pressure 51.8 dB(A). Standby loss is listed as — W (not specified).
