Product details

The screw-type terminals on the magnet coil accept solid or stranded conductors from 0.5 to 4 mm², matching standard panel wiring practice.

The coil is rated 24 V DC nominal. At that rated value the main contacts carry 10 A — that is the continuous current the contactor can handle in its primary duty. For DC switching at other voltages, the rating drops: 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 AC-3 maximum operating rate is 750 cycles per hour, which covers most motor-starting applications without excessive wear. Operating temperature range is -25 to +60 °C, with storage from -55 to +80 °C — fine for unheated enclosures as long as the enclosure ambient stays within the operating band.

The Size S00 footprint is 45 mm wide, 58 mm tall, 117 mm deep — a space-efficient block that leaves room for auxiliary contact blocks or a separate overload relay on the same rail. Mounting position is flexible: ±180° rotation on a vertical surface, and can be tilted forward/backward by ±22.5° on a vertical surface. Clearances: 10 mm upward, 10 mm forward, 10 mm downward, 6 mm at the sides.

How do I get current pricing and availability for 3RT2015-1QB41?

Submit an RFQ through the storefront. The part is sourced to order against a quote; availability and current pricing are confirmed at that time through independent distribution channels.

What are the key dimensions and mounting clearances?

The Size S00 contactor measures 45 mm wide, 58 mm tall, and 117 mm deep. Required clearances: 10 mm upward, 10 mm forward, 10 mm downward, and 6 mm at the sides. It snaps onto 35 mm DIN rail per DIN EN 60715.

What wire sizes does the screw terminal accept?

The screw-type terminals accept solid or stranded conductors from 0.5 to 4 mm². For two-wire connections: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm².
