Product details

AS-i compact reversing starter with integrated brake

The Siemens 3RK1322-0FS02-1AA3 is an AS-interface compact reversing starter in an IP65-rated enclosure, rated for 0.12 kW AC-3 motor duty at 400 V with a setting range of 0.35 to 0.5 A. The electromechanical switching contact and bimetal motor protection make it a self-contained motor branch for reversing applications on a conveyor, gate, or actuator — no separate overload relay or contactor assembly needed inside a cabinet.

AS-interface bus integration and motor brake output

This starter communicates via AS-interface protocol, with bus communication enabled and two integrated inputs for local sensors or pushbuttons. The built-in motor brake output (product component Motor brake output = Yes) handles a 400 V AC brake coil directly, eliminating an external brake rectifier or contactor for motors with spring-applied brakes — a common requirement on vertical-axis or holding applications. The main current circuit connects via tab terminals, so it's wired with quick-connects rather than screw clamps, which speeds replacement on a live line.

Frequently asked questions

What is the depth and width of this starter?

The depth is 190 mm and the width is 120 mm. The overall height is 270 mm. These dimensions fit a typical machine-mounted junction box or a small local control station, not a standard DIN-rail panel.

Does this starter work with a motor that has a holding brake?

Yes, the starter includes a motor brake output rated for 400 V AC, so it can switch a spring-applied brake coil directly without an external brake contactor or rectifier.

What is the short-circuit breaking capacity?

The maximum short-circuit breaking capacity (Icu) at 400 V is 50 000 A. This allows the starter to clear high-fault currents without requiring upstream fuses to blow, simplifying selective coordination.

Can this replace a panel-mounted reversing contactor and overload?

In terms of function, yes — it combines reversing contactor, overload relay (bimetal), and short-circuit protection (circuit-breakers) in one IP65 package. But it is not a DIN-rail panel component; it is a self-contained enclosure meant for machine mounting. Panel wiring to tab terminals differs from screw-clamp contactor wiring.
