Product details

Coil and switching ratings

The coil pulls in at 85 % of rated voltage (initial value 0.85) and drops out at 1.85 times rated (full-scale value 1.85). That dropout margin means the contactor stays sealed through brief sags on a 24 V DC bus — useful in a mill control cabinet fed by a shared power supply. Switching capacity drops with voltage: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. The DC arcing time runs 10–15 ms, with an operate time at DC of 5–20 ms.

Termination and mounting

Spring-type terminals accept solid or stranded wire from 0.5 to 4 mm², including two conductors per clamp (2x 0.5–4 mm²). No screw torquing needed — strip to the right length and push in. It takes 45 mm width on the rail, 70 mm height, 121 mm depth.

Frequently asked questions

What wire sizes does the 3RT2015-2WB41 accept?

Solid or stranded wire from 0.5 to 4 mm², including two conductors per clamp (2x 0.5–4 mm²).

Where can I buy the 3RT2015-2WB41?

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

Will the 3RT2015-2WB41 drop into a panel specified for the 3RT2015-2SB41?

Both are S00 frame contactors with the same physical footprint (45 mm width, 70 mm height, 121 mm depth) and DIN rail mounting. The difference is the coil: the 2WB41 uses a 24 V DC coil, while the 2SB41 uses a different coil voltage. If the panel wiring and power supply match 24 V DC, the swap is mechanical — no rewiring of the main contacts needed, but verify the coil supply.
