SIEMENS 3RT20261AN20 208V AC 3P 25A Contactor
The SIEMENS 3RT20261AN20 is an IEC magnetic contactor rated for 25 A inductive and 40 A resistive loads at 208 V AC across three poles. It suits panel builders and maintenance engineers who need reliable motor switching in industrial control circuits. The unit belongs to the SIRIUS 3RT20 series with frame size S0.
Upgrade from lower-rated or non-IEC contactors
This contactor replaces older starters that lack IEC compliance or carry lower current ratings for the same coil voltage. The jump is worth it when the application demands 25 A inductive capacity with a 220 V AC coil and a compact 3.55 in by 2.15 in footprint. It is not for systems requiring reversing operation or a built-in enclosure.
DIN rail or surface mount with screw terminals
Installation is straightforward using DIN rail or surface mounting with screw terminal connections for secure wiring. The 1NO/1NC auxiliary contacts integrate easily into control schemes. Common issues include mismatched coil voltage if the supply differs from 220 V AC and insufficient clearance for the stated overall dimensions.

Questions about this item
What mounting options does the S0 frame provide for this 25 A contactor?
The unit is designed for DIN rail or surface mounting as indicated by the frame style.
What wiring step is often missed when connecting the 208 V AC coil and three power poles?
Secure all screw terminals for the coil and each pole before energising the circuit.
Which parts of this IEC starter typically need replacement after extended switching duty?
The main power contacts and the 1NO/1NC auxiliary contacts are the wear items to inspect periodically.
