3RT1017-1AV01

What type of component is this?

It is a Siemens SIRIUS three-pole power contactor designed for switching electrical loads in industrial control applications.

What is the rated operating current?

The rated operating current is 22 A for AC-1 loads at 400 V and an ambient temperature of 40 °C. For AC-3 motor applications at 400 V, the rating is 12 A.

What motor power can this contactor control?

For AC-3 applications, the contactor is rated to control motors up to 5.5 kW at 400 V.

What control coil voltage does it require?

The contactor requires a 400 V AC control supply and is suitable for both 50 Hz and 60 Hz operation.

How many main contacts does it have?

It has three normally open main contacts and no normally closed main contacts, making it suitable for three-phase load switching.

Does it include an auxiliary contact?

Yes. The 3RT1017-1AV01 includes one instantaneous normally open auxiliary contact and no instantaneous normally closed auxiliary contacts.

What is the enclosure protection rating?

The front and terminals are rated IP20, providing protection against contact with fingers and similarly sized solid objects. Installation within a suitable electrical enclosure is normally required.

What terminal connection type is used?

Screw-type terminals are provided for the main circuit, auxiliary circuit and control circuit.

How is the contactor mounted?

It supports screw mounting and snap-on installation onto a 35 mm standard mounting rail in accordance with DIN EN 50022.

What are the dimensions of the contactor?

The unit measures approximately 45 mm wide, 57.5 mm high and 72 mm deep. A 6 mm side clearance from earthed parts is specified.

What ambient temperatures are suitable for operation?

The specified operating ambient temperature range is from -25 °C to +60 °C, with a maximum installation altitude of 2,000 metres above sea level.

What conductor sizes can be connected?

Depending on conductor construction and terminal arrangement, the screw terminals accept metric conductor sizes from 0.5 mm² up to 4 mm². Compatible AWG configurations include sizes from 20 AWG to 12 AWG.

What short-circuit fuse ratings are specified?

For the main circuit, the specified gL/gG fuse rating is 35 A for coordination type 1 or 20 A for coordination type 2. The auxiliary contact circuit requires a 10 A gL/gG fuse.

What is its typical mechanical endurance?

The contactor has a typical mechanical endurance of 30 million operating cycles. This figure may be lower when particular auxiliary contact blocks are fitted.

What should be checked before selecting it as a replacement?

Confirm the 400 V AC coil voltage, 50/60 Hz frequency, three-pole arrangement, AC-3 rating of 12 A, motor rating of 5.5 kW at 400 V, integrated normally open auxiliary contact, screw terminals, S00 size and mounting dimensions.
