Schneider Electric ATV212HD37N4 ATV212 37 kW HVAC Drive 480 V

ATV212HD37N4 in plain terms: a 37 kW drive for pumps and fans

The ATV212HD37N4 is a Schneider Electric Altivar 212 variable speed drive, listed in its datasheet as: variable speed drive ATV212 – 37kW – 50hp – 480V – 3ph – EMC – IP21. The Altivar 212 range is specified for pumps and fans in HVAC and building services, and this reference is a 37 kW (50 hp) drive and the first on the tallest 240 x 550 x 244 mm body, for large HVAC pumps and fans drawing about 79 A. Seven Star LLC supplies the ATV212HD37N4 in Oman and the GCC as an independent supplier in Muscat.

Reading the reference: ATV212 is the range named in the datasheet, and the title gives the rest, namely 37 kW, 50 hp, 480 V, three-phase, EMC filter and IP21. Use the figures in the table below rather than decoding the letters, because the datasheet does not publish a decoding key.

ATV212HD37N4 datasheet values at a glance

Availability status of the ATV212HD37N4

The datasheet of the ATV212HD37N4 carries the notices “Discontinued on: 26 Aug 2026” and “To be discontinued”. This page therefore describes a drive that the manufacturer has withdrawn. Seven Star LLC can only say what is obtainable once you send the enquiry, and a project that needs a long service life should ask about a current alternative.

Installing the ATV212HD37N4 in a panel

The ATV212HD37N4 measures 240 mm wide, 550 mm high and 244 mm deep, and its datasheet gives no net weight. The power terminals L1/R, L2/S and L3/T take 50 mm² / 1/0 AWG at a tightening torque of 24 N.m, 212 lb.in, while the control terminals take 2.5 mm² at 0.6 N.m.

Cable data in the datasheet distinguishes IEC cable without the mounting kit (copper 90 °C XLPE/EPR or 70 °C PVC at 45 °C) from UL 508 cable with the UL Type 1 kit (copper 75 °C PVC at 40 °C), which is relevant if the panel is built to both regimes. The relative humidity limit is 5 to 95 % without condensation, so condensation control matters in coastal switchrooms.

Output current, overload and control of the ATV212HD37N4

At 37 kW the ATV212HD37N4 lists a line current of 68.9 A at 380 V; 54.4 A at 480 V and an apparent power of 52 kVA at 380 V. The continuous output current is 79 A at 380 V; 79 A at 460 V with a transient of 86.9 A for 60 s, so the motor nameplate current must stay below 79 A if the drive is to carry it continuously; the transient figure only covers short overload.

Output frequency runs from 0.5 to 200 Hz with a speed range of 1 to 10. The motor control profiles include voltage/frequency ratio (2 points, 5 points, automatic IR compensation), an energy-saving quadratic U/f profile for fans and pumps, and sensorless flux vector control. Transient overtorque is 120 % of nominal motor torque for 60 s, and ramps are adjustable from 0.01 to 3200 s or automatic according to the load.

The line short-circuit rating is listed as 22 kA. Treat it as a design input for the supply side and compare it with the fault level of the board that feeds the drive.

Where the ATV212HD37N4 is applied in Oman and the GCC

Across Oman and the GCC, air-conditioning load dominates summer electricity demand, so HVAC fans and pumps are among the most valuable motors to put on a drive. The ATV212HD37N4 suits chilled-water and condenser pumps, AHU supply and extract fans and cooling-tower fans on buildings, hospitals, malls and utility plants.

The energy-saving U/f profile and the PI regulator listed in the datasheet allow pressure or temperature loops to be closed inside the drive. In dusty or very hot sites, keep filters and heat-sink fins clean, because the thermal limit of the drive is reached before the motor shows any distress.

Heat loss and cooling of the ATV212HD37N4

The datasheet gives a power dissipation of 976 W and an air flow of 334 m3/h for the ATV212HD37N4, with a noise level of 64 dB. Use these two numbers when you size the enclosure: the dissipation is the heat that has to leave the panel, and the air flow is the volume the drive fan moves.

The operating range is -10 to 40 °C (without derating); 40 to 50 °C (with derating factor), so in a hot switchroom the derating factor above 40 °C is not a footnote but a design condition. The datasheet gives the operating position as vertical within 10 degrees. The datasheet gives no net weight for this reference, so ask for the shipping weight before planning lifting or wall loads.

Before you order the ATV212HD37N4

• Motor nameplate current at or below 79 A, at 380 to 480 V three-phase.
• Application: pump or fan with a quadratic torque curve, as the HVAC profile assumes.
• Supply: 380 to 480 V -15/+10 %, 50 or 60 Hz; check the line short-circuit level against the Isc figure.
• Enclosure: heat loss of 976 W and air flow of 334 m3/h.
• Building-automation protocol required: Modbus, BACnet, METASYS N2, APOGEE FLN or LonWorks (option card).
• Lifecycle status accepted, as the datasheet marks the reference discontinued.
