SIEMENS 3RT20261AK60 Contactor 1NO/1NC 110/120V AC 3P 25A

SKU CH-Z5JH-BKC6R

IEC magnetic contactor with 3 poles, 25 A inductive rating and 110/120 V AC coil for DIN-rail mounting

  • Reliable motor switching with 25 A inductive rating
  • Space-saving 2.2 in width fits tight panels
  • Direct 110/120 V AC coil eliminates extra transformers
  • Flexible DIN rail or surface mounting options
  • SIRIUS 3RT20 series built for industrial durability

SIEMENS 3RT20261AK60 Contactor

The SIEMENS 3RT20261AK60 is an IEC magnetic contactor rated for 25 A inductive and 40 A resistive loads at three poles. It suits control panels and motor-starting circuits that need a compact 110/120 V AC coil and a single normally-open plus normally-closed auxiliary contact. Industrial electricians and OEM panel builders will find it matches standard IEC frame S0 dimensions.

DIN-rail or surface mounting with screw terminals

The unit mounts on a standard DIN rail or directly on a surface using screw terminals for power and control wiring. Its 3.6 in height and 2.2 in width leave room in crowded enclosures, while the 1NO/1NC auxiliary block handles interlock or signalling duties without extra accessories. No enclosure is included, so the installer provides the required IP rating.

Upgrade from non-reversing IEC starters

This contactor replaces older non-reversing IEC starters that lack the SIRIUS 3RT20 frame’s auxiliary contacts or screw-terminal layout. The jump is worthwhile when a panel needs both power switching and a built-in 1NO/1NC feedback circuit in the same footprint. It does not suit reversing applications or installations that demand an integrated enclosure.

Questions about this item

Will the 25 A inductive rating hold continuously without overheating?

The contactor is rated for 25 A inductive and 40 A resistive full-load current, so sustained operation at or below 25 A inductive stays within its thermal design.

How much heat and noise does the coil produce when energised all day?

The 110/120 V AC coil on the SIRIUS 3RT20 frame S0 runs silently with only a faint hum; heat rise is low enough for side-by-side DIN-rail mounting in a closed cabinet.

What auxiliary circuit wiring do I need to use the built-in 1NO/1NC contacts?

Two screw-terminal auxiliary contacts (1NO + 1NC) are integrated; just run control wires to the marked terminals — no extra blocks or relays required.
