Product details

Side-by-side mounting is supported with a 6 mm gap at the side for heat dissipation.

The AC-3 motor-switching rating at 400 V is 3 A, which translates to roughly 1.5 kW for a standard induction motor — sized for small pumps, fans, or conveyor drives. For resistive loads (AC-1), the contactor carries 10 A at 400 V. The DC coil draws 3.3 W holding power, which is low enough to keep the control transformer small.

Integration notes

The IP20 front and IP20 terminal protection require the contactor to be installed inside a panel or enclosure. For type 2 coordination (no weld under fault), use a 20 A gL/gG fuse upstream; for type 1 coordination, a 35 A fuse is allowed.

Frequently asked questions

What is the depth of 3RT1016-1BF42?

The depth is 72 mm, which fits standard 100 mm deep enclosures with clearance for wiring.

What wire sizes does the screw terminal accept?

The main circuit terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and up to 2x (0.75 to 4 mm²) solid or stranded. For AWG, that is 2x (20 to 16), 2x (18 to 14), and 1x 12.
