In fields such as industrial automation, smart home appliances, energy management, and transportation systems, the demands on relays—the core control components—have far surpassed simple switching functions. Engineers now use stability, high load capacity, long lifespan, and outstanding safety as the guiding principles for their selection criteria. This idea is embodied in the FANHAR FH51/FH51TP series power relays.
Ultimate Performance: With a switching capacity of 13,850VA and switching currents up to 50A, it easily manages high-power surges.
Uncompromising Safety: Featuring a 4kV high insulation strength, an 8mm creepage distance, and esteemed international safety certifications such as UL, TUV, and CQC, this system ensures the protection of both personnel and equipment.
Exceptional Durability: 500,000 mechanical cycles and stable electrical life at 85°C significantly reduce maintenance costs and failure rates.
Flexible Adaptability: It offers PCB and quick-connect installation options, as well as solder mask and plastic seal protection structures. These features make it perfectly suited to diverse applications, ranging from cleanrooms to harsh industrial environments.
Environmental Leadership: We are fully compliant with RoHS directives, helping your products to meet global environmental regulations.
Contact System: The Power Core, Built to Last
Premium materials: The contacts are made of AgSnO₂ (silver tin oxide) material. This material is renowned for its exceptional arc resistance. It is also known for its superior wear resistance. And it is known for its anti-welding characteristics. It performs exceptionally well in scenarios involving frequent switching. It also performs well in scenarios involving high surge currents. In all of these scenarios, it maintains a consistently low contact resistance of ≤50mΩ.
Multiple Configuration Options:
2A (2 Form A): Two separate typically open contacts that can be used for parallel control or backup systems.
2C (2 Form C): Two changeover connections, providing enhanced flexibility in circuit control logic.
A broad coil voltage range of DC 5V to DC 110V allows it to adapt to a variety of control circuit drive needs.With coil power consumption as low as 1.7W, it achieves rapid engagement (actuation/reset time ≤25ms) while effectively conserving energy and reducing heat buildup at the control end.
