Product details

ATEX and IECEx certified for hazardous-area motor starting

The 3RW5524-1HA06: This soft starter carries both ATEX and IECEx certification, meaning it is approved for use in potentially explosive atmospheres — a requirement for pump and fan drives in oil/gas, chemical, and grain-handling installations.

Trip class selection and motor protection

Configurable trip classes — Class 10A, 10E (default), 20E, or 30E per IEC 60947-4-2 — let you match the thermal overload curve to the motor start profile: Class 10A for short-duration starts (centrifugal pumps), Class 30E for high-inertia loads (conveyors, crushers). The accuracy class is 5 per IEC 61557-12, meaning the current measurement error stays within ±5 % of reading — tight enough for reliable overload protection without nuisance tripping.

Fieldbus connectivity and control features

Built-in PROFIBUS, Modbus RTU, Modbus TCP, and EtherNet/IP support means this unit drops into most common industrial networks without an external gateway — the integrator just sets the node address and baud rate. PROFIenergy is supported via PROFINET communication modules, enabling energy-saving pauses during idle periods — useful in automated production lines with intermittent duty cycles.

Motor control functions for demanding applications

Includes DC braking, combined braking, pump ramp down, breakaway pulse, and torque control — features that handle stopping pump columns without water hammer, breaking high-inertia loads, and starting sticky or seized machinery. The voltage ramp start reduces mechanical shock on the driveline, while the breakaway pulse delivers a short torque boost to overcome static friction before ramping to full speed.

Panel integration and mounting clearances

Required clearances: 100 mm above, 75 mm below, 10 mm in front, 5 mm at the sides, 0 mm behind. Screw terminals simplify wiring — no special crimp tools needed for the power connections. The service factor of 1.15 allows continuous operation at 115 % of rated current without tripping, matching typical NEMA motor service factors.

Global approvals and compliance documentation

CE marking for European markets, UL and CSA approval for North America — this unit meets the certification requirements for most industrial installations worldwide. ATEX and IECEx certification is listed directly on the unit, so it can be installed in Zone 1 or Zone 2 hazardous areas without additional external protection barriers.

Frequently asked questions

Does the 3RW5524-1HA06 support Modbus TCP?

Yes, it supports Modbus TCP, Modbus RTU, PROFIBUS, and EtherNet/IP — all built-in without requiring an external communication module.

What trip classes are available on the 3RW5524-1HA06?

The unit is configurable for Class 10A, 10E (default), 20E, or 30E per IEC 60947-4-2. Class 10A suits short-duration starts; Class 30E handles high-inertia loads.

What are the mounting clearances required for the 3RW5524-1HA06?

Minimum clearances: 100 mm above, 75 mm below, 10 mm in front, 5 mm at the sides, and 0 mm behind the unit. These ensure adequate airflow for cooling.
