NNC Power Relay 71F Series
In industrial automation, power systems, and new energy applications, the performance of power relays directly impacts the safety and stability of equipment operation. Traditional power relays often face challenges such as contact erosion, high temperature rise, and short lifespan. The NNC 71F Power Relay redefines reliability standards in power control with innovative technology and exceptional design, offering three core advantages.
✅ Advantage 1: High Load Capacity with Unwavering Stability
The 71F utilizes special silver alloy contacts and magnetic blowout arc extinguishing technology, supporting a maximum load capacity of 50A/440VAC and withstanding 8 times instantaneous overcurrent impact. Certified by UL, VDE, and CE, it delivers an electrical lifespan of over 100,000 cycles, maintaining stable performance even in heavy-load scenarios with frequent switching.
✅ Advantage 2: Intelligent Temperature Control & Efficient Heat Dissipation
Featuring innovative cooling fin design and metal composite housing, it reduces temperature rise by over 50% and operates reliably across a wide temperature range of -40°C to +85°C. The built-in temperature monitoring protection mechanism prevents overheating risks in real-time, ensuring long-term reliability in high-temperature environments.
✅ Advantage 3: Comprehensive Safety Protection for Worry-Free Operation
The fully enclosed dust-proof design achieves an IP67 protection rating, effectively preventing dust and moisture intrusion. With an isolation voltage of up to 5000VAC between coil and contacts, and equipped with overvoltage protection and status indication, it provides all-round safety for industrial applications.
