SIEMENS

SIEMENS 3RT20171AP61 IEC Magnetic Contactor 1NO 220/240V AC 3P 12A

SKU CH-DJRD-C5M9N

IEC magnetic contactor with 12 A inductive rating, 3 poles, 220/240 V AC coil and 1 NO auxiliary contact

  • Reliable switching with 12 A inductive rating
  • Handles 22 A resistive loads for heating circuits
  • 220/240 V AC coil suits standard control voltages
  • Three-pole design controls three-phase motors
  • DIN-rail or surface mounting simplifies installation

IEC Magnetic Contactor 12 A 3-pole

This SIEMENS SIRIUS 3RT20 contactor switches three-phase loads up to 12 A inductive or 22 A resistive. A 220/240 V AC coil drives the main contacts and one normally-open auxiliary contact. The S00 frame mounts on DIN rail or surface with screw terminals.

Suits panels needing compact non-reversing switching

Ideal for motor-starter assemblies, lighting circuits or heating loads that fit the 12 A inductive rating. Not for applications requiring reversing operation, higher current poles or built-in overload protection.

Fits DIN rail or screw-mounted enclosures

Screw terminals accept standard ferrules or solid wire for quick wiring. The 3.08 in height and 1.97 in width leave space for adjacent devices. No enclosure is included so the installer selects the required IP rating.

Questions about this item

What coil voltage must the control circuit supply for this contactor to operate?

The coil is rated for 220/240V AC, so the control circuit must provide that voltage.

Can this non-reversing contactor be paired with an existing reversing starter?

This unit is non-reversing; a separate reversing contactor or mechanical interlock would be required for reversing duty.

How can I verify the contactor is functioning after wiring it on the DIN rail?

Energise the 220/240V AC coil and confirm the three main poles close and the 1NO auxiliary contact changes state.
