Product details

The Siemens 3RT2015-2MB41-0KT0 is a SIRIUS coupling contactor in size S00, designed for switching DC loads in control circuits.

Coil and switching performance

The coil is rated 24 VDC, with a pickup threshold of 0.85 × rated (20.4 V) and a dropout of 0.15 × rated (3.6 V), so it holds in through brownout conditions down to about 20 V and drops cleanly below 4 V. Switching capacity at 24 VDC is 10 A, dropping to 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V; at 400 VDC it handles 3 A. These are DC-13 ratings for solenoid loads — the arcing time runs 10 to 15 ms, and the contactor is rated for 20 to 12 A on the main contacts depending on duty.

Frequently asked questions

Where can I buy 3RT2015-2MB41-0KT0 and how do I get a price?

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

What wire sizes does the spring terminal accept?

The spring-type terminals accept solid or stranded wire from 0.5 to 4 mm², including two conductors per clamp.

What is the DC switching capacity at various voltages?

At 24 VDC it switches 10 A; at 48 V and 60 V, 2 A; at 110 V, 1 A; at 125 V, 0.9 A; at 220 V, 0.3 A; at 400 V, 3 A.
