Panel fit and mounting constraints
The 3RW5144-1XC14: Envelope is 210 mm wide, 417 mm high, 203 mm deep; clearance requirements are 100 mm upwards, 75 mm downwards, 10 mm forwards, 5 mm sideways, and 0 mm backwards — plan the backplane and adjacent devices accordingly.
Operating envelope and derating
Rated for a minimum operating current of 100 A across 200-480 V — this is the floor for the motor FLA the starter must handle; the unit supports inside-delta wiring for reduced current draw. Trip class is configurable to CLASS 10A (default), 10E, or 20E per IEC 60947-4-2, matching the motor start profile without nuisance trips on high-inertia loads.
Fieldbus and HMI integration
Supports PROFIBUS, Modbus RTU, and PROFINET standard — the control circuit uses screw-type terminals; the fieldbus interface is onboard, no external gateway needed for these three protocols. Includes a standard HMI and a High Feature HMI option; the analog output is configurable as 4-20 mA (default) or 0-10 V via the High Feature HMI parameter set. Firmware update capability and an error logbook are built in — supports traceable fault recording for qualification documentation.
Environmental and compliance robustness
Shock rated at 15 g / 11 ms (with potential contact lifting above 12 g / 11 ms); vibration resistance is 15 mm at 6 Hz and 2 g up to 500 Hz — suitable for rotating machinery and conveyor applications. Degree of pollution 3 per IEC 60947-4-2, meaning it tolerates conductive pollution in industrial atmospheres without conformal coating on the enclosure. Service factor is 1 — no continuous overload margin beyond the set current; the 15% minimum load relative to the smallest settable Ie ensures stable operation on lightly loaded motors.
