Product details

Panel fit and ventilation clearance

The 3RW5215-3TC14 measures 275 mm high by 170 mm wide by 152 mm deep. Screw fixing to the backplate is the standard mount; the mounting surface can tilt +/-10° from vertical. Ventilation gaps are mandatory: 100 mm above, 75 mm below, 10 mm forward, 5 mm to the side, and 0 mm backward. Without these clearances, the internal heatsink cannot shed the IGBT losses and the unit derates prematurely. Shock tolerance is 15 g / 11 ms.

Motor protection and trip class

Trip Class 10A is the default setting per IEC 60947-4-2, with selectable 10E and 20E profiles. Minimum settable current is 11.5 A, which sets the lower bound of the motor FLA it can protect. The minimum load is 15 % of the smallest settable Ie.

Fieldbus and control integration

The 3RW5215-3TC14 supports PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET. PROFIenergy is available with the PROFINET communication module. Firmware updates are supported in the field. An error logbook is accessible with special accessories. Auto-reset and remote reset by cycling the control supply voltage are standard.

Wiring terminals and power connections

Solid wire terminations accept two conductors per clamp: 1.0...2.5 mm² for control circuits, and 2.5...10 mm² for the main power path. Rated supply voltage is 200...480 V at 50/60 Hz.

Approvals and compliance documentation

The product category is hybrid switching devices.

Frequently asked questions

What is the trip class of the 3RW5215-3TC14?

The default trip class is CLASS 10A per IEC 60947-4-2, with selectable CLASS 10E and CLASS 20E profiles. Class 10A provides a 10-second maximum trip time at 7.2× Ie, suitable for standard motor starting duty.

What fieldbus protocols does the 3RW5215-3TC14 support?

It supports PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET. PROFIenergy is available when used with the PROFINET communication module.

What approvals does the 3RW5215-3TC14 carry?

The product is classified as a hybrid switching device.

What are the mandatory ventilation clearances for this soft starter?

Required clearances are: 100 mm above, 75 mm below, 10 mm forward, 5 mm to the side, and 0 mm backward. Without these, the unit will derate above 40 °C ambient.
