Product details

The 3RW5114-1XC14: For higher-inertia loads (centrifuges, crushers), switching to Class 20E gives a longer acceleration window before a trip. The unit supports both Voltage Ramp and Soft Torque starting profiles. Starting voltage is adjustable from 30-100 %; the stopping voltage is fixed at 50 %. Inside-delta connection is supported, which lets you size the soft starter for 58 % of the motor FLA when wired in the delta leg — a common panel trick to reduce unit cost on larger motors.

Fieldbus and HMI — no extra gateway needed

PROFIBUS DP, PROFINET IO, and Modbus RTU are all onboard — no external communication module required. The HMI-Standard and HMI-High Feature variants give you a local display for parameter readout and fault log access without a laptop. The analog output is configurable as 4-20 mA (default) or 0-10 V, so you can feed motor current or speed feedback straight to a PLC analog input or a panel meter.

Mounting and clearances for panel layout

Dimensions are 321 mm high, 185 mm wide, 203 mm deep. Mounting is by screw fixing; the unit can be tilted ±10° on a vertical surface. Minimum clearances around the unit: 100 mm above, 75 mm below, 10 mm in front, 5 mm at the sides, 0 mm at the rear. Plan the panel layout so the top vent isn't blocked by a busbar or another device.

Control wiring and diagnostics

Control connections use screw-type terminals — standard ferrule or ring-tongue. Remote reset is supported by cycling the control supply voltage off and on. The error logbook is stored internally, so when you power-cycle to clear a fault, the history stays. Auto-reset is also available if the application allows unattended restart after a trip.

Frequently asked questions

What fieldbus protocols does the 3RW5114-1XC14 support?

PROFIBUS DP, PROFINET IO, and Modbus RTU are all integrated onboard. No external gateway or comm module is required for any of these.

What are the panel clearance requirements for this soft starter?

Minimum clearances: 100 mm above, 75 mm below, 10 mm in front, 5 mm at the sides, 0 mm at the rear. These ensure adequate airflow for the -25 to +60 °C operating range (derate above 40 °C).
