Schneider Electric ATV310H075N4E Altivar 310 0.75 kW Drive

What the ATV310H075N4E drive is and how its reference reads

Buyers who search for the ATV310H075N4E usually already know the motor: 0.75 kW, three-phase, 380–460 V. The datasheet confirms that this Altivar 310 drive matches that duty, is built with a heat sink, and is the unfiltered variant, with no EMC filter. The paragraphs below translate the published figures into the questions that come up when a drive like this is specified.

The datasheet states the supply as 380–460 V with a tolerance of −15 % to +10 %, at 50/60 Hz ± 5 %. Output frequency runs from 0.5 to 400 Hz and the product destination is asynchronous motors. The datasheet lists no EMC filter on this reference, so installations that need conducted-emission control must plan the filtering separately or choose the filtered sibling where one exists in the size.

ATV310H075N4E technical specifications

Where the ATV310H075N4E fits in Oman and the GCC

Small ratings like this suit single conveyors, small ventilation fans, metering and dosing pumps and packaging lines. In Oman and the wider GCC such machines run in desalination plant auxiliaries, utility buildings, water treatment, light industry and oil and gas support systems. Heat and dust are the practical challenges: the drive is rated to 55 °C without derating and carries dust class 3S2, but the cabinet design still decides how long it lives.

Mounting, cooling and ambient limits for the ATV310H075N4E

It measures 143 × 72 × 140 mm and weighs 0.8 kg. This is the smallest frame in the group: 143 mm high and 72 mm wide, self-cooled with no fan to maintain. It must be mounted vertically within ± 10 degrees. Power terminals accept 1.5–2.5 mm², 16 AWG–14 AWG and the datasheet gives a tightening torque of 0.8–1 N.m.

For operation the datasheet allows -10 to 55 °C without derating. From 55 to 60 °C the protective cover on the top of the drive must be removed and current derated by 2.2 % per °C. Storage is allowed from −25 to 70 °C, humidity 5–95 % without condensation, and altitude up to 1000 m without derating. Protection is IP20 without the blanking plate on the upper part, with IP4X on top. The environmental classes quoted are 3S2 for dust and 3C3 for chemical pollution.

Protection and motor control functions of the ATV310H075N4E

Fault coverage listed is broad for a drive of this size: supply over- and undervoltage, phase loss at the input, earth-fault overcurrent, motor-phase short circuit, drive overheating and I²t thermal motor protection.

Motor control profiles are V/f, V/f with energy saving (quadratic), and sensorless vector control, with adjustable slip compensation. Ramps are linear from 0 to 999.9 s, with S and U shapes available. Standstill braking is by DC injection for up to 30 s. Braking torque reaches up to 70 % of nominal motor torque without a braking resistor; the datasheet does not list a resistor-assisted figure for this reference.

Speed range is 1 to 20 for an asynchronous motor, and transient overtorque is 170 to 200 % of nominal motor torque depending on drive rating and motor type.

Control terminals and Modbus communication on the ATV310H075N4E

Control wiring is the same logic across the Altivar 310 family, so panel builders can reuse their terminal layout when a motor changes size. This unit offers 4 programmable logic inputs, 1 analogue input, 1 analogue output and 2 outputs, one of them a protected C/O relay.

The Modbus port on the front face supports function codes 03, 06, 16, 23 and 43, so a PLC or SCADA gateway can read and write drive registers and identify the device. Each logic input is sampled every 20 ms, and the analogue input every 10 ms, which is worth remembering when a fast reference change is expected.

How the ATV310H075N4E is rated: heavy duty only

Unlike the larger Altivar 310 drives, this one carries a single published rating. The datasheet lists 0.75 kW (1 hp) on heavy duty with 2.3 A continuous output and a transient of 3.5 A for 60 s, which is a margin of about 1.5 times the continuous figure. No separate normal-duty column exists, so a motor that needs more than 2.3 A on a steady load should move up to the next frame.

Line current is 3.5 A at 380 V and 3.1 A at 460 V, with a prospective line short-circuit rating of 5 kA. Power dissipation at rated current is 34.1 W, a figure that matters when the drive sits in a closed panel.

What to send with an RFQ for the ATV310H075N4E

• Part number and required quantity
• Motor nameplate: kW, rated current, voltage and frequency, and whether the load is constant or variable torque
• Duty basis: heavy duty, and the supply voltage actually available on site
• Whether an EMC filter is required, given that this reference is the unfiltered variant, with no EMC filter
• Panel conditions: cabinet size, ambient temperature, altitude
• Delivery location in Oman or the GCC and required date

Choosing the ATV310H075N4E against neighbouring Altivar 310 ratings

The nearest references in the same Altivar 310 supply class are listed below, sorted by heavy-duty power. When a motor sits right on a boundary, compare continuous output current, not kilowatts, because this drive is judged on 2.3 A at heavy duty.

Remember that the supply-voltage range, 380–460 V, is common to every reference here; if your network is 230 V single-phase or 690 V, this series is not the right branch of the catalogue.
