IEC Magnetic Contactor for Motor Control
The SIEMENS 3RT20281AK60 is a three-pole IEC magnetic contactor built for switching inductive loads up to 38 A and resistive loads up to 50 A. It operates on a 110 V to 120 V AC coil and includes one normally open and one normally closed auxiliary contact. The unit suits panel builders and maintenance teams wiring motor starters or lighting circuits in industrial environments.
Screw Terminals and DIN Rail Mounting
Connections use screw terminals that accept standard ferrules or solid wire for secure, tool-tightened joints. The contactor carries no enclosure rating, so it must be installed inside a suitable cabinet. A frame size S0 body measuring 4.18 in high by 2.13 in wide clips onto DIN rail or can be surface mounted with screws, allowing flexible layout in new panels or retrofit jobs.
Non-Reversing Starter Replacement
This contactor replaces a worn non-reversing starter of the same frame size and coil voltage when the auxiliary contact arrangement matches 1NO/1NC. The jump is worth it when the existing unit shows contact erosion or coil failure and the application does not need reversing capability. Buyers who need a reversing pair or a different auxiliary count should select an alternative model.
