Product details

Its 24 VDC coil pulls in at rated voltage and holds with a 6 A inrush at 24 V.

Screw terminals on both main and auxiliary circuits accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded copper. AWG equivalents are 2x (20 to 16), 2x (18 to 14), or 2x 12. The auxiliary switch extension option (product extension auxiliary switch: yes) means you can add a side-mount block for status feedback without losing the main contact footprint.

Environmental limits and what they mean

The insulation voltage is rated 690 V, matching the AC-3 maximum operating voltage.

Mechanical life is 30,000,000 operations typical — that's the contactor body itself, not the contacts under load. For actual switching, the maximum operating frequency depends on duty: AC-1 (resistive) allows 1,000 cycles per hour; AC-3 (motor starting) allows 750 cycles per hour; AC-4 (plugging/reversing) allows 250 cycles per hour; DC switching allows 10,000 cycles per hour. For most conveyor or pump applications running at AC-3, 750 cycles/hour is roughly one start every 5 seconds — adequate for high-speed pick-and-place but not for continuous inching duty.

Frequently asked questions

What is 3RT6015-1BB41's listed depth and width?

Depth is 73 mm, width is 45 mm, height is 57.5 mm. The 45 mm width is a standard S00 size footprint that fits alongside other S00 contactors on DIN rail without extra spacing.

What compliance documentation does this brand provide for 3RT6015-1BB41?

RoHS compliance date is 05/01/2012, meeting EU RoHS requirements. The product carries the SIRIUS brand designation and is designed to IEC/EN 60947-4-1 standards for contactors. Specific UL/CSA certification status should be confirmed from the manufacturer's declaration.
