Products Features
1. Comprehensive and reliable protection functions: With dual core functions of overcurrent protection and short-circuit protection, it can quickly respond to current anomalies, effectively avoid damage to lines and equipment, and reduce safety risks; the protection characteristics are accurate, the tripping accuracy is high, and there is no "false tripping" or "refused tripping" problem.
2. Wide range of applications: Adaptable to the global mainstream AC 50/60Hz grid frequency, rated voltage 240/415V covers single-phase and three-phase distribution lines, rated operating current up to 63A adapts to most lighting and small power circuits, and 4.5KA/6KA short-circuit breaking capacity adapts to medium and low voltage distribution scenarios.
Advanced and convenient design: The modular design is easy to install, assemble and maintain, and is compatible with standard distribution boxes to improve space utilization. The compact size allows for multi-circuit configuration in limited spaces.
3. Performance meets standards and is stable: Strictly in compliance with the IEC60898-1 international standard, with high-quality materials and reliable structure, it can operate stably for a long time in different environments, reducing the probability of failure and extending service life.
4. With control function: Under normal circumstances, it can complete infrequent line switching operations, simplify the distribution system structure, and meet the operational requirements of maintenance, equipment rotation and other scenarios.
