Product details

It occupies a 45 mm wide footprint on the rail, 70 mm tall, 121 mm deep — a standard S00 envelope that drops into existing panel layouts without re-drilling. The coil is rated for 24 VDC; the contactor's DC switching capability covers 6 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, and 0.2 A at 440 V. These are the DC-1 resistive-load ratings — for inductive DC loads, derate further per the manufacturer's curve.

Switching frequency and thermal limits

Maximum operating cycles per hour depend on duty: 1 000 at AC-1 (resistive), 750 at AC-2 and AC-3 (motor start/run), 250 at AC-4 (plugging/inching). The AC-3e rating also caps at 750 cycles/h. For a conveyor or pump running continuous AC-3 duty, that 750 cycles/h ceiling means the contactor can handle about one start every 4.8 seconds — fine for most process lines, but not for high-repetition indexing stations.

Spring-type terminals on the magnet coil accept solid or stranded wire from 0.5 to 4 mm², and up to 2x (0.5 to 4 mm²) for paralleled conductors. The main contact terminals are screw-type, accepting 20 to 12 AWG. Clearance distances: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the side — standard for S00, so no surprise when laying out adjacent devices.

Frequently asked questions

What are the DC switching ratings for this contactor?

DC-1 resistive load ratings: 6 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, and 0.2 A at 440 V.

What is the closest functional alternative to 3RT2016-2CP04-3MA0?

The 3RT2016-1AG62 is a size S00 contactor in the same SIRIUS family, but it uses screw-type terminals instead of spring-type on the coil, and its coil voltage differs. The 3RT2015-1AV02 and 3RT2015-1AV01 are smaller-frame S00 contactors with lower current ratings. None are a direct drop-in without checking coil voltage and terminal style.

Where can I buy 3RT2016-2CP04-3MA0 and how is it quoted?

This part is sourced through independent distribution and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time.
