Product details

Rated for 4.5 kW at 500 V and 5.5 kW at 690 V, it handles motors up to those power levels. At 24 V it carries 10 A, at 230 V it carries 6 A, covering control transformers and small heaters.

Pollution degree 3 confirms it tolerates conductive dust in industrial environments. Maximum altitude of 2000 m means no derating needed for most installations below that height.

Screw-type terminals accept solid conductors: 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², and up to 2x 0.75 to 4 mm². AWG equivalents are 2x 20-16, 2x 18-14, and 1x 12. Side-by-side mounting is allowed, saving rail space. For type 2 coordination (no weld) use a gL/gG fuse rated 20 A. For type 1 coordination (weld allowed, safe fault clearing) use 35 A. This protects the contactor during short circuits.

Typical mechanical endurance is 30,000,000 cycles, giving a long service life in cyclic applications. For procurement, this is a standard BOM line item; RFQ for pricing and lead time.

Frequently asked questions

What is the depth of this contactor?

The depth is 72 mm. Combined with the 45 mm width and 57.5 mm height, it fits compactly on a DIN rail.

What wire sizes does the screw terminal accept?

The screw terminals accept solid conductors: 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², and up to 2x 0.75 to 4 mm². AWG equivalents are 2x 20-16, 2x 18-14, and 1x 12.

What is the difference between 3RT1016-1AR02 and 3RT1016-2AP02?

The 3RT1016-2AP02 uses spring-cage terminals instead of screw-type terminals. The 3RT1016-1AR02 has screw terminals, which may be preferred for high-vibration environments or where maintenance staff are more familiar with screw clamps. Both share the same S00 frame size, coil voltage, and power ratings.
