Dimensions and mounting — panel fit
The 3RW5126-1XC14-0S measures 321 mm high, 185 mm wide, and 203 mm deep, secured by screw fixing.
Rated current and voltage — what drives the selection
Minimum operating current is 32 A, with a rated voltage range of 200 to 480 V at 50/60 Hz. The minimum load is 15 % of the smallest settable Ie, so it handles lightly loaded motors without dropping out.
Trip class and starting profile
Trip class is configurable: CLASS 10A (default), 10E, or 20E per IEC 60947-4-2. Starting voltage is adjustable from 30 to 100 %, with a fixed stopping voltage of 50 %. Voltage ramp, soft torque, and ramp-down (soft stop) are all standard — useful for pumps or conveyors where mechanical shock needs limiting.
Fieldbus and control connectivity
Onboard PROFIBUS, Modbus RTU, and PROFINET standard — no extra gateway module needed. The control circuit uses screw-type terminals. Analog output is 4…20 mA (default) or 0…10 V (parameterizable with High Feature HMI). Remote reset is supported by cycling the control supply voltage.
Environmental and derating
Pollution degree 3 per IEC 60947-4-2. Shock resistance is 15 g / 11 ms (12 g / 11 ms with potential contact lifting). Vibration resistance: 15 mm to 6 Hz, 2 g to 500 Hz.
