Product details

The 24 VDC coil pulls in at 0.8 of rated voltage and holds across the full operating range of -25 to +60 °C. That 10 A at 24 VDC switching rating tells you it handles DC control circuits and small DC motors; the 7.6 A at 480 V and 9 A at 600 V cover common North American motor voltages for smaller three-phase loads. Mechanical life is typical 30 million operations. At AC-3 duty (standard motor switching) it's rated 750 operations per hour; at AC-4 (inching/plugging) that drops to 250 per hour. The arcing time of 10–15 ms and DC operate time of 7–13 ms are what you'd expect for a contactor this size — fast enough for most sequencing but not a high-speed DC switch. That lets you pack S00 contactors on a DIN rail with minimal gap, but verify the arc flash boundary if you're grouping them without barriers.

Coil connection is ring cable lug — not a spring-cage or screw-clamp terminal. Factor in the lug crimp tool and ring terminal size when wiring the panel; it's a solid connection but slower to terminate than push-in types.

Frequently asked questions

Where can I buy 3RT2016-4BB42 and what is the lead time?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm lead time and price.

Will 3RT2016-4BB42 drop into a panel built for 3RT2015-4BB41?

Both are S00 frame contactors with the same 45 mm width and DIN rail mounting, so the mechanical fit and panel cutout are identical. The difference is the coil voltage: 3RT2016-4BB42 is 24 VDC; 3RT2015-4BB41 uses a different coil rating. Verify the control voltage before swapping.

What are the key dimensions for panel layout?

Width is 45 mm, height 58 mm, depth 73 mm. Clearance above and below the contactor is 10 mm; side clearance is 6 mm. That's the S00 frame envelope.
