The FH66NE-200 is a latching relay designed for high-reliability industrial and energy applications. The fundamental value resides in the seamless amalgamation of high-current carrying capacity, exceptional insulating safety standards, and robust mechanical performance. It is particularly suitable for fields that demand extremely high reliability in electrical connections, such as photovoltaic power generation systems, industrial automation control, and high-power power management.
Powerful Current Handling Capability: Rated switching current up to 200A, maximum switching voltage 830VAC, with a switching capacity of 166 kVA. It can seamlessly manage high-power switching operations such as DC-side interruption and pre-charge circuit regulation in photovoltaic inverters.
Efficient and Low-Loss Contact System: Utilises silver tin oxide (AgSnO₂) contact material, distinguished by a very low initial contact resistance (≤2mΩ) and enhanced resistance to arc erosion and welding, hence ensuring extended contact stability during frequent high-current switching.
Rapid Response and Control: Operating (pull-in) and release times are within 30ms and 10ms respectively, providing quick response to meet the requirements of precise timing control and reduce system wait time.
Extended Service Life and Durability: Mechanical life of up to 1 million operations, electrical life can reach 30,000 cycles under specific load test conditions, significantly reducing equipment maintenance frequency and lifecycle costs.
Robust Environmental Adaptability: The operating temperature range extends from -40℃ to +85℃ and incorporates a dust-proof (flux-proofed) structural design. It can adjust to intricate working environments, including severe outdoor climates and industrial dust, guaranteeing uninterrupted and reliable equipment functionality.
Exceptional Insulation Safety: Insulation resistance surpasses 1000 MΩ. The coil and contacts can endure a 2500VAC, 1-minute withstand voltage test, ensuring a dependable safety isolation barrier between the high-voltage and low-voltage control sides.
Enhanced Structural Reliability: The product has passed stringent vibration and shock tests (vibration 10-55Hz, shock 980m/s²), ensuring the internal structure and connection integrity remain intact during transportation and operation under mechanical stress.
Authoritative International Safety Certifications: The product has successfully obtained multiple international safety certifications including UL, C-UL, TÜV, and CQC. These certifications cover not only high-voltage applications like 830VAC but also common industrial voltage levels such as 277VAC, confirming its compliance with global mainstream safety standards and serving as a reliable passport for equipment entering domestic and international markets.
The FH66NE-200 provides several common coil voltage options for seamless integration into diverse control systems, spanning from DC 6V to 48V. Each specification distinctly delineates the exact pull-in/release voltage thresholds, coil resistance, rated power consumption, and explicitly defines the holding voltage range. It enables pulsed energy-saving control, ensuring reliable operation while effectively preventing coil overheating from prolonged energisation.
