Below that floor, the current sensing loses accuracy and the trip class timing may not hold. Rated voltage covers 200 to 480 V, so it fits standard low-voltage three-phase supplies across North America (208/240/480 V) and Europe (230/400 V) without a separate transformer tap. ## Trip class 10A — 10 seconds to manage heat buildup Trip class is set to CLASS 10A by default, with selectable 10E and 20E options per IEC 60947-4-2. ## Fieldbus onboard — PROFIBUS, Modbus, EtherNet/IP, PROFINET The unit ships with PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET communication. No separate gateway module is needed for these four protocols — the soft starter talks directly to the PLC or SCADA. PROFIenergy is supported via the PROFINET standard module, allowing energy management data collection during idle phases. ## Pump-specific features — Soft Torque and Pump Ramp Down Soft Torque reduces the starting torque below the motor's locked-rotor torque, which helps on conveyors or pumps where a hard start can damage the belt or cause water hammer. Pump Ramp Down controls deceleration to prevent pressure surges when stopping a centrifugal pump — the unit ramps voltage down gradually rather than cutting power instantly. Auto-reset and remote reset by cycling the control supply are standard, so the starter can re-close after a fault without a manual pushbutton visit — useful for remote or unmanned stations.","metaTitle":"Siemens 3RW5225-1TC04 Soft Starter, 25.5 A min, 200-480 V","metaDescription":"Siemens SIRIUS 3RW5225-1TC04 soft starter, 25.5 A minimum operating current, 200–480 V rated voltage.
