Product details

It's rated for motor switching at 4 kW in AC-2 duty at 400 V, and 5.5 kW at 690 V. The 24 V DC coil pulls 3.3 W to close and holds at the same 3.3 W — no extra holding-power budget needed.

The front face carries IP20 finger-safe protection; the terminals are also IP20. Dimensions are 45 mm wide, 57.5 mm tall, and 114 mm deep — fits a standard S00 footprint.

Ratings and coordination

Main contacts are rated 10 A in AC-12 (resistive) duty. For motor loads, AC-2 at 400 V delivers 4 kW; AC-4 at 400 V is 8.5 A. The contactor carries pollution degree 3 and operates from -25 °C to +60 °C, with a maximum altitude of 2 000 m. Type 2 coordination requires a 20 A gL/gG fuse; type 1 coordination uses a 35 A gL/gG fuse.

Auxiliary contacts and coil

Includes 2 instantaneous auxiliary contacts (no NC main contacts). The auxiliary contacts are rated 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V. Coil pick-up is at 0.85 x rated voltage; drop-out is at 1.1 x rated voltage. Main circuit connections use solder pin connectors.

Frequently asked questions

What is the depth of 3RT1016-5BB44?

The depth is 114 mm.

What is the width of 3RT1016-5BB44?

The width is 45 mm.

Will 3RT1016-5BB44 drop into a panel specified around 3RT1015-1BB42 without rewiring?

No — the 3RT1015-1BB42 uses a 24 V AC coil, while the 3RT1016-5BB44 uses 24 V DC. The coil supply must be changed, and the frame sizes differ (S0 vs S00), so the mounting hole pattern and terminal layout may not align.

What compliance documentation does this brand provide for 3RT1016-5BB44?

The part carries a reference code per DIN EN 81346-2 (Q). The manufacturer typically provides CE, UL, CSA, and RoHS declarations for the SIRIUS series, but specific certifications are not listed in this evidence.
