Product details

Active production — SIRIUS hybrid soft starter for motor starting duty

The 3RW5224-1AC15: Rated 200-600 V, it covers the common low-voltage motor networks worldwide — 400 V three-phase in Europe, 480 V in North America, and 575 V in Canada — without needing a voltage variant.

Trip class and motor protection coordination

The trip class is set to CLASS 10A by default, with selectable CLASS 10E and CLASS 20E, all per IEC 60947-4-2. The minimum load is 15 % relative to the smallest settable Ie — important for applications where the motor is oversized or lightly loaded; below that threshold the soft starter may not detect the load correctly.

Fieldbus connectivity and control interfaces

This unit supports PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET standard — five fieldbus protocols on one hardware platform. PROFINET also carries PROFIenergy for energy management during idle phases. An analog output is provided, defaulting to 4-20 mA, parameterizable to 0-10 V when used with the High Feature HMI. Remote reset is possible by cycling the control supply voltage — useful for automated restart after a fault.

Mounting and environmental limits for panel integration

The enclosure measures 203 mm deep, 185 mm wide, and 306 mm high — a substantial footprint that demands careful panel layout. Fixing is by screw fixing onto a mounting plate; DIN-rail snap-on is not listed, so plan for drilled and tapped backplate or threaded inserts. Mounting position allows ±10° rotation and can be tilted forward or backward on a vertical surface. Clearance requirements: 100 mm upwards, 10 mm forwards, 75 mm downwards, 5 mm at the side, and 0 mm backwards — the zero backwards clearance means it can sit flush against a panel wall or another device. Shock resistance is 15 g / 11 ms, dropping to 12 g / 11 ms if contact lifting is a concern.

Frequently asked questions

What fieldbus protocols does the 3RW5224-1AC15 support?

It supports PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET standard. PROFINET also includes PROFIenergy for energy management.

What is the trip class and what does it mean for motor starting?

CLASS 10E and CLASS 20E are also selectable — CLASS 20E gives a longer window for high-inertia loads.

What are the mounting clearances for the 3RW5224-1AC15?

Clearance requirements: 100 mm upwards, 10 mm forwards, 75 mm downwards, 5 mm at the side, and 0 mm backwards. The zero backwards clearance allows flush mounting against a panel wall.
