Power contactors (AC-3) from ABB, Schneider Electric and Siemens start and stop three-phase motors and switch heavy loads. The range covers over 650 products from 6 A to 2650 A, with motor ratings from 2.2 kW to 450 kW, mostly in 3 and 4 pole versions. Stoklink ships worldwide from Turkey and quotes project volumes on request.
What's in this range
How to choose
- Motor power and current in AC-3 at your supply voltage. Do not size from the AC-1 value.
- Pole count: 3P for motors, 4P where the neutral is switched.
- Coil voltage and type, AC or DC, against the control supply.
- Short-circuit protection and overload relay matched to the contactor, following the manufacturer's coordination tables.
- Auxiliary contact needs and whether add-on blocks fit the frame.
FAQ
What does AC-3 mean on a contactor?
AC-3 is the IEC 60947-4-1 category for starting and stopping squirrel-cage motors. Ratings in AC-3 are usually lower than AC-1 for the same frame.
Can I replace a contactor with another brand?
Check rated current in AC-3, pole count, coil voltage and mounting dimensions. Auxiliary contacts and coordination with the overload relay must also match.
Do you ship contactors outside Turkey?
Yes. Stoklink ships worldwide from Turkey on EXW terms. Lead time depends on distributor stock, so send the part numbers for a quote. Project quantities are quoted on request.
