Frequently Asked Questions - 3RW5234-6AC15 SIEMENS

What is the operating current rating of the 3RW5234-6AC15?

The rated operating current is 113 A at 40°C (direct connection) and 196 A at 40°C (inside-delta circuit). It derates at higher temperatures.

What control supply voltage does the soft starter require?

It requires 110-250 V AC at 50/60 Hz. The tolerance is -15% to +10%.

Can the soft starter be used with an inside-delta motor connection?

Yes, the 3RW5234-6AC15 supports inside-delta circuit operation. The current settings and power ratings differ for this configuration.

What communication options are available?

Optional communication modules for PROFINET, EtherNet/IP, Modbus TCP, Modbus RTU, and PROFIBUS can be installed.

How do I adjust the motor current?

Use the rotary encoding switch on the device. It has 16 positions corresponding to current values from 53 A to 113 A (direct) or 91.8 A to 196 A (inside-delta).

What is the ambient temperature range for operation?

The device can operate from -25°C to +60°C. However, derating (reduction in current capacity) is required above 40°C.

Does the soft starter provide motor overload protection?

Yes, it includes electronic motor overload protection with trip classes CLASS 10A (default), 10E, and 20E according to IEC 60947-4-2.

What are the mounting requirements?

Mount vertically on a flat surface. Minimum spacing: 10 mm forward, 0 mm backward, 100 mm upward, 75 mm downward, and 5 mm on sides for airflow.

How can I reset the device after a fault?

The device supports automatic reset (auto-reset) and manual reset. Remote reset is possible by cycling the control supply voltage off and on.

Where can I find the user manual or technical support?
