Product details

This is a Siemens SIRIUS reversing motor starter, order code 3RK1315-6KS71-3AA5, designed for controlling and protecting motors that need to run in both directions — conveyors, hoists, or any reversing load. The AS-Interface bus connection (M12 plug for addressing) means it drops into an AS-i network directly, with 4 digital inputs and 1 digital output on board for local feedback or control.

The IP65 enclosure is washdown-rated, so this starter can be mounted in food processing, packaging, or any area where hosed cleaning is routine.

Supply and mounting

Supply voltage is 24 V DC nominal, with a range of 20.4 to 28.8 V DC — standard for industrial control power. The starter is screw-fixed (not DIN rail) and can be mounted vertically, horizontally, or flat, giving flexibility for tight panels or machine-mounting. The main power connection uses a HAN Q4/2 plug per ISO 23570, so the wiring harness is factory-made and the connection is a single plug-in; no field wiring of motor cables inside the enclosure.

Frequently asked questions

What is the rated motor power at 400 V?

It is rated at 0.75 kW at 400 V for the main motor circuit, which is the AC-3 rating for reversing duty.

What communication protocol does it use?

It uses AS-Interface (AS-i) for fieldbus communication. It does not support PROFIBUS DP or PROFINET natively.

What protection class does the enclosure have?

It is rated IP65, meaning it is dust-tight and protected against low-pressure water jets from any direction — suitable for washdown environments.
