Specifications Parameter Category Specification Manufacturer / Series ABB / Softstarter TFC Series Model Code 2TFC800-104R1001 Rated Current 104 Amperes (This is the maximum rated operational current for the soft starter under specific conditions). Rated Voltage Typically 200-480V AC, 3-phase, 50/60 Hz (Confirm exact voltage range from local datasheet, as it can vary by market). Application For controlling Three-Phase AC Squirrel Cage Induction Motors. Power Rating Approximately 55 kW / 75 HP (at 400V AC). This is an approximate value; the exact power depends on the motor voltage and application. Control Method Voltage ramp control. It provides a smooth increase in voltage during start and a controlled decrease during stop (e.g., for pump control to avoid water hammer). Key Features • Reduced Starting Current: Limits inrush current, typically to 250-400% of motor full load current (FLC). • Torque Control: Provides high starting torque while minimizing mechanical shock. • Built-in Protection: Includes overload protection, phase imbalance detection, and thermal protection for the starter itself. • Compact Design: Integrated bypass contactor (or internal bypass) to reduce heat dissipation during continuous run. • User Interface: Typically includes a set of potentiometers or DIP switches for adjusting start/stop parameters and LEDs for status indication. Enclosure / Mounting Generally supplied as an open-type chassis for panel mounting (IP00). Requires installation in a suitable control cabinet for protection. Communication & Options Basic models often have analog/digital I/O for integration into control systems. Optional communication modules (e.g., Fieldbus) may be available. Standards & Compliance Conforms to international standards such as IEC/EN 60947-4-2, UL 508, and CE marked. Typical Applications Centrifugal Pumps Fans and Blowers Compressors Conveyor Belts Mixers and Agitators
