2. Key Selling Points- Accurate and Reliable Motor Protection: Provides comprehensive protection including overload, stall,
phase loss, phase current imbalance, and earth fault (with external
zero-sequence CT), ensuring high trip accuracy and effectively
preventing motor damage from electrical faults, extending equipment
life.
- Electronic Design, Immune to Ambient Temperature: Utilizes electronic sensing technology instead of bimetallic
strips, offering stable protection characteristics unaffected by
ambient temperature changes, ensuring consistent and accurate
performance in varying conditions.
- Wide Adjustable Current Range: Features a broad current setting range (e.g., 250–600A),
easily adjustable via DIP switches or dials, accommodating motors
of various power ratings, enhancing application flexibility and
reducing spare part inventory.
- Modular Mounting, Space-Saving: Designed for direct mounting onto ABB A105 series contactors,
forming a compact electromagnetic starter combination without
additional wiring or brackets, saving valuable panel space and
simplifying assembly.
- Clear Status and Fault Indication: Integrated LED indicators provide real-time visibility of
operating status, fault types (e.g., overload, phase loss), and
trip causes, enabling quick troubleshooting and reduced downtime.
- High Reliability and Durability: Built with ABB industrial-grade quality and premium
components, offering excellent electromagnetic compatibility (EMC)
and long-term stability, suitable for demanding environments such
as high temperature and dust.
