Product details

The Siemens 3RW5536-6HA04 is a solid-state soft starter rated for a supply voltage of 200 to 480 V, designed for three-phase induction motor starting in industrial control panels. It carries ATEX and IECEx certification for use in potentially explosive atmospheres, and its trip class is selectable among CLASS 10A, 10E (default), 20E, or 30E according to IEC 60947-4-2 — meaning you can match the overload protection curve to the motor's thermal capacity and the starting duty cycle.

Fieldbus & Analog Feedback

This soft starter supports Modbus RTU, Modbus TCP, EtherNet/IP, and PROFIBUS natively, so it drops into most common automation networks without an external gateway. The analog output can be configured for 4-20 mA or 0-10 V, giving the PLC a direct process-variable signal for current or torque monitoring. Mounts on a panel backplate — the 306 mm height, 185 mm width, and 203 mm depth require 100 mm clearance above and 75 mm below for ventilation; side clearance is 5 mm. Screw terminals are standard, so no special crimp tooling needed.

Frequently asked questions

Is 3RW5536-6HA04 compatible with Modbus TCP?

Yes, it supports Modbus TCP natively, as well as Modbus RTU, EtherNet/IP, and PROFIBUS.

What is the trip class of 3RW5536-6HA04?

The trip class is selectable: CLASS 10A, 10E (default), 20E, or 30E per IEC 60947-4-2. This lets you set the overload curve to match the motor's thermal limit and starting duration.
