2. Key Selling Points- Comprehensive and Precise Motor Protection: Provides multiple protection functions including overload,
stall, phase loss, phase sequence error, phase current imbalance,
and earth fault (with external zero-sequence CT), with high trip
accuracy to effectively prevent motor damage from electrical faults
and ensure production continuity.
- Electronic Technology, Immune to Environmental Influence: Utilizes advanced electronic sensing and microprocessor
control, offering stable and reliable protection characteristics
unaffected by ambient temperature changes, ensuring accurate
response under various operating conditions.
- Wide Current Adjustment Range, Flexible Matching: Features a broad adjustable current range (e.g., 320–600A),
easily set via DIP switches, suitable for various high-power motor
applications, reducing spare part inventory and enhancing system
configuration flexibility.
- Modular Mounting, Space and Cost Saving: Designed for direct mounting onto ABB A300 series contactors,
forming a compact electromagnetic starter combination without
additional brackets or complex wiring, significantly saving panel
space and reducing installation and maintenance costs.
- Clear Operation and Fault Status Indication: Equipped with LED indicators for real-time display of power,
running, fault (e.g., overload, phase loss), and trip status,
enabling fast fault diagnosis, minimizing downtime, and improving
maintenance efficiency.
- High Reliability and Industrial-Grade Durability: Built with ABB industrial-grade quality, offering excellent
electromagnetic compatibility (EMC), wide operating temperature
range, and long-term stability, suitable for demanding industrial
environments such as high temperature, humidity, and dust.
