Product details

The S00 frame keeps the footprint tight at 45 mm wide, 58 mm tall, and 73 mm deep — important for high-density cabinet layouts where every millimeter of DIN rail counts.

The main contacts are rated for 20 A down to 12 A, covering small to medium motor loads. The 24 VDC coil draws 10 A at rated value — that's the holding current, not the inrush; the DC operating time is 7 to 13 ms, and arcing time runs 10 to 15 ms, so the contactor responds fast enough for standard motor starting sequences. Switching frequency varies by duty: up to 1000 cycles per hour for resistive loads (AC-1), 750 cycles/h for motor starting (AC-2 and AC-3), and 250 cycles/h for plugging or inching (AC-4). If your application involves frequent reversing or jogging, the AC-4 limit is the one that governs contact life — don't size based on the AC-3 number alone.

Frequently asked questions

What are the key dimensions of the 3RT2015-1BN41?

Width is 45 mm, height is 58 mm, and depth is 73 mm — the S00 frame size that fits standard DIN-rail panels.

What wire sizes does the 3RT2015-1BN41 accept?

Solid and stranded conductors from 0.5 to 4 mm² are accepted on the main terminals, with dual-wire capability for 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm².

Does the 3RT2015-1BN41 include an auxiliary contact?

Yes, an auxiliary switch is integrated into the contactor, eliminating the need for a separate add-on block for basic signaling or interlock functions.
