In the pursuit of high-performance and high-reliability electrical control, the FH30L-90 Series High-Power Magnetic Hold Relays are your ideal choice. Designed specifically for demanding high-current, high-voltage applications, this product combines high-current switching, ultra-long lifespan, and energy efficiency into one core component for electric vehicle charging stations, smart home control systems, and industrial lighting control.
90A High-Current Switching: It effortlessly handles high-load circuits with a rated capacity of 90 A at 277 V AC or 90 A at 60 V DC, delivering a maximum switching capacity of 22,500 VA (AC) and 5,400 W (DC).
Robust short-circuit withstand capability: Exceptional electrical endurance enables reliable breaking of up to 2000A short-circuit current (0.3ms duration) for 300 cycles, ensuring system safety.
High mechanical durability: A mechanical life of up to 500,000 operations is guaranteed, ensuring stability during long-term, frequent use.
Stable Electrical Life: With an underrated load, the electrical life of the AC load reaches 6,000 operations, while the life of the DC load exceeds 10,000 operations. This significantly reduces the frequency of maintenance and replacement.
Premium Contact Material: It utilises AgSnO₂ (silver tin oxide) contacts with a contact resistance of ≤2 mΩ. These contacts offer superior resistance to arc erosion and welding.
Multiple coil options: Standard and sensitive (low-power) types, along with single-coil and dual-coil configurations, accommodate diverse drive circuit requirements. Sensitive coils consume as little as 1.5W for energy efficiency.
Optional manual control: For system debugging, maintenance and emergency operations, manual control switches are a feature of select models.
PCB Mounting: Compact design (minimum dimensions 39.0×15.0×30.2mm) suits high-density PCB layouts, simplifying your product structure design.
Dual encapsulation protection: It offers flux-proofed versions for clean environments and fully plastic-sealed types for harsh industrial settings containing contaminants such as H₂S and SO₂.
Robust insulation performance: The insulation resistance exceeds 1000 MΩ and the dielectric strength between the coil and the contacts reaches 4000 VAC. This effectively prevents breakdowns. It also ensures the safety of both the operator and the equipment.
Wide Temperature Range Operation: It functions reliably from -40°C to +85°C and has a humidity tolerance of 5%–85%, ensuring stable performance in extreme temperatures.
Electric Vehicle AC Charging Piles: This serves as the primary power control switch and acts as the core execution unit for safe and reliable charging.
Smart Home/Building Systems: It allows you to control and switch your central air conditioning, high-power electric heating, smart lighting and similar systems remotely.
Industrial Automation & Power Management: Achieves efficient circuit switching. Achieves efficient energy distribution. This is in UPS, energy storage systems (ESS) and distribution cabinets.
Home Appliances & Commercial Equipment: Good for big machines that use a lot of electricity, like coffee makers, baking machines, and water pumps.
This series primarily includes two main models:
FH30L-90: It is specifically designed for AC loads and is ideal for use with charging stations and smart home applications.
FH30LD-90: Optimized for DC loads, suitable for photovoltaic systems, DC charging modules, and similar scenarios.
