Product details

Trip class and overload protection — what it means for motor starting

The 3RW5134-1XC14-0S is configured with Trip Class 10A as default, with selectable 10E and 20E classes per IEC 60947-4-2. Rated minimum current is 53 A, so this unit is sized for motor loads drawing at least that at full load. The voltage range covers 200 to 480 V, covering common low-voltage industrial supplies across 50/60 Hz systems.

Fieldbus and control — PROFIBUS, Modbus RTU, PROFINET onboard

This soft starter ships with PROFIBUS, Modbus RTU, and PROFINET standard interfaces — no separate communication module needed. That means it drops into a Siemens S7 environment or any Modbus TCP/PROFINET controller without a gateway. The control circuit uses screw-type terminals, and the unit supports voltage ramp start, soft torque, and ramp-down soft stop — giving you adjustable acceleration and deceleration profiles for pumps, conveyors, and fans where mechanical shock matters.

Mounting and clearances — panel fit checklist

Dimensions are 324 mm high, 185 mm wide, 203 mm deep. Mounting is by screw fixing, with the unit positionable on a vertical surface with ±90° rotation and ±22.5° tilt front/back. Required clearances: 100 mm upwards, 10 mm forwards, 75 mm downwards, 5 mm at the sides, and 0 mm backwards — so plan for airflow above and below. Pollution degree 3 per IEC 60947-4-2 means it's rated for industrial environments with conductive dust or occasional condensation.
