Key Parameters 1. Main Ratings: Rated Operational Current, Ie: 160 A - This is the maximum continuous current the starter is rated for under specified conditions. Rated Operational Voltage, Ue: Up to 690V AC, 50/60 Hz. Controlled Motor Power: Approximately 75 kW / 100 HP at 400V AC. (Exact power depends on supply voltage and motor characteristics; always verify against the manufacturer's selection table). Utilization Category: AC-53a for squirrel-cage motors with soft starting/stopping. 2. Control & Performance: Starting Control: Voltage ramp soft start. Reduces starting torque and inrush current by controlling the voltage applied to the motor terminals. Stopping Control: Optional soft stop (deceleration ramp) or free coast stop. Torque Control: Provides smooth, stepless acceleration, protecting mechanical drives and belts. Inrush Current Limiting: Can limit starting current typically to 250-400% of motor full-load current (FLC), compared to 600-800% for Direct-On-Line starters. 3. Integrated Protection Features: Electronic Overload Protection: Built-in protection against motor overload, phase loss, and phase imbalance. Overcurrent / Short Circuit Protection: NOT INCLUDED. This starter requires external short-circuit protection, such as a properly sized fuse (aM/gG type) or a circuit breaker, connected upstream. This is a critical installation detail. 4. Control & Communication: User Interface: Typically features a keypad and LCD display for local configuration, status monitoring, and fault diagnostics. Control Terminals: Digital inputs for Start/Stop/Jog commands, relay outputs for "Ready," "Running," or "Fault" signaling. Communication: Many models in this series offer optional communication modules (e.g., Modbus RTU, DeviceNet, PROFIBUS DP) for integration into automation networks. 5. Mechanical & Environmental: Enclosure: Provided as an open-type device (IP00). Must be installed in a suitable control panel/enclosure to provide protection against dust, moisture, and accidental contact (typically to at least IP2X or IP54 as required by the application). Mounting: Designed for DIN rail or panel mounting. Cooling: Internally fan-cooled for efficient heat dissipation. Operating Temperature: Typically -25°C to +60°C (with derating above 40°C or 50°C). 6. Electrical Connections: Main Terminals: Screw terminals for three-phase power input (L1, L2, L3) and output to the motor (T1, T2, T3). Control Terminals: Removable plug-in connectors for control wiring. 7. Certifications: Complies with international standards such as IEC/EN 60947-4-2, UL 508, CE, cULus, etc. 8. Typical Applications: Centrifugal Pumps: Eliminates water hammer. Fans & Blowers: Reduces belt and bearing stress. Conveyor Systems: Provides smooth starts and stops, preventing material spillage. Compressors: Reduces pressure surges in pipelines. Mixers and Agitators: Gentle handling of sensitive products.
