Rated 7 A / 3 kW at 400 V (AC-3), the Siemens 3RT2015-1AP01 is a 3-pole SIRIUS 3RT2 contactor, size S00, operated by a 230 V AC, 50/60 Hz coil. It has 1 NO integrated auxiliary contact, and Siemens rates it at 18 A for resistive (AC-1) loads at 40 °C. Per the Siemens data sheet the coil picks up within 9 … 35 ms and drops out within 4 … 15 ms.
Contactors in pump, fan, conveyor and compressor panels may switch thousands of times a day, and contact wear is the usual reason for replacement. Keeping a spare of the same order number avoids long stoppages.
See our Siemens industrial controls range, including SIRIUS 3RU2 overload relays and 3RV2 motor starter protectors for the same size.

Typical applications
- Switching heaters and resistive loads (AC-1)
- Conveyor, mixer and packaging machine drives
- Replacement of a worn 3RT2 contactor with the same rating
- Compact starter combinations with 3RV2 or 3RU2 in size S00
Compatibility and replacement
For overload protection mount a SIRIUS 3RU2 thermal overload relay of size S00 directly under the contactor, or combine it with a 3RV2 motor starter protector of the same size using the Siemens link module. Older 3RT10 contactors were replaced by the 3RT20 series; send us the old order number and we will confirm the current equivalent.
Frequently asked questions
Can I use it for a 7.5 kW motor?
This contactor is rated 3 kW at 400 V (AC-3, 7 A). Choose a contactor whose AC-3 rating at your supply voltage is at least the motor rating.
Which overload relay fits it?
A SIRIUS 3RU2 overload relay of size S00, for example 3RU2116, set to the motor full-load current.
Can I get a price and delivery time?
Prices are quoted on request. Send the order number, quantity and delivery country on WhatsApp and we will reply with price and delivery time; air shipping is usually 5 to 7 days once ready, with a 1-year warranty.
Before you order
