Panel fit and mounting — 306 x 185 x 203 mm
The 3RW5227-1AC05 measures 306 mm high, 185 mm wide, and 203 mm deep — screw-fixing mount, not DIN rail. Clearance requirements: 100 mm above, 75 mm below, 10 mm forward, 5 mm at the sides, and zero backward clearance needed. That 203 mm depth plus forward clearance means the enclosure depth must be at least 213 mm from the backplane to the door.
Motor starting duty — 40.5 A minimum, trip class options
Rated for a minimum motor current of 40.5 A at 200-600 V AC. The trip class is configurable: default CLASS 10A, with CLASS 10E and CLASS 20E available per IEC 60947-4-2. CLASS 20E gives a longer 20-second ramp for high-inertia loads, reducing thermal stress on the motor during start.
Fieldbus and control — PROFIBUS, PROFINET, Modbus, EtherNet/IP
Built-in support for PROFIBUS, PROFINET standard, Modbus RTU, Modbus TCP, and EtherNet/IP — no separate communication module needed for these protocols. Also supports PROFIenergy for energy management when used with a PROFINET communication module. The analog output is configurable as 4-20 mA or 0-10 V via the High Feature HMI. Remote reset is available by cycling the 24 V DC control supply.
Environmental and approvals — UL, CSA, CE, pollution degree 3
Carries UL, CSA, and CE marking — accepted in North American and European installations. Pollution degree 3 per IEC 60947-4-2 means it tolerates conductive pollution in industrial atmospheres. Operating temperature range -25 to +60 °C, with derating required above 40 °C. Shock resistance 15 g / 11 ms, with potential contact lifting above 12 g.
