LL-10A Series Overcurrent Relay Product Introduction
The LL-10A series overcurrent relay is a high-performance control component specifically engineered for power system protection and industrial equipment applications. Suitable for both AC/DC circuits, it delivers real-time current anomaly detection and rapid circuit interruption, providing reliable overload and short-circuit protection for power grids, renewable energy systems, and industrial automation scenarios.
Key Features:
-
Precision Detection & Instant Response
Equipped with advanced current sampling technology, the device covers a broad detection range from 0.5A to 200A with response time under 15ms. Its adaptive threshold adjustment mechanism effectively distinguishes between transient current fluctuations and genuine fault signals, ensuring protection reliability without false triggering.
-
Enhanced Safety Architecture
Dual-contact output structure incorporates silver-alloy main contacts, delivering 5000-operation mechanical endurance and 100A breaking capacity. Integrated arc suppression and high-temperature resistant ceramic base ensure stable performance across -25℃ to +70℃ environments.
-
Intelligent Operation Management
Dual-indication system combines LED status lights with mechanical flag indicators, supporting local/remote mode switching. Optional RS485 communication module enables real-time data transmission for seamless integration into digital power management systems.
-
Engineering-Optimized Design
Compact housing complies with 35mm DIN rail standards, allowing vertical/horizontal mounting orientations. Transparent protective cover facilitates parameter verification, while spring-clamp terminals accept up to 4mm² conductors for tool-free installation.
Typical Applications:
• DC-side protection in photovoltaic inverters
• Branch circuit protection for LV distribution cabinets
• Motor starting current supervision
• Rail traction system protection
• Energy storage device circuit management
