The FH14T-E is a high-performance power relay that has been introduced by Zhejiang FANHAR Electronics. Thanks to its robust 32A switching capability, wide operating temperature range of up to 105°C and ultra-compact PCB mounting design, it occupies a prominent position in the fields of industrial control, home appliances and new energy. This product is designed to be highly reliable. It provides conventional coil configurations. These satisfy rigorous mechanical and electrical performance requirements. This is the case in harsh situations.
Robust Load Handling Capability
Rated load: 32A 250VAC (resistive load), enabling control of high-power equipment.
600VAC is the maximum switching voltage, giving applications more voltage margin.
Maximum switching capacity: 8864VA, ensuring stable performance under complex load conditions.
Minimum applicable load: 7202VA, demonstrating excellent performance even under moderate loads.
The contact material, silver tin oxide (AgSnO₂), greatly increases the electrical lifespan of the relay by providing greater resistance to arc erosion and weld resistance.
Exceptional Environmental Adaptability and Reliability
Extended operating temperature range: -40°C to +105°C. Ensures stable operation and high reliability even in high-temperature environments (e.g., inside motor controllers, charging station power modules).
High insulation rating: Complies with UL Class F insulation system standards, guaranteeing electrical insulation performance at elevated temperatures.
Superior electrical insulation characteristics:
Insulation resistance: Initial value ≥100MΩ (tested at 500VDC).
Dielectric strength:
Between open contacts: 1500VAC (standard gap type) / 2000VAC (large gap BG type), sustained for 1 minute.
Between the coil and the contacts: 2,500 V AC, sustained for one minute, providing robust isolation protection.
Robust Environmental Resistance: Offers two configurations: Flux-proofed and Plastic-sealed. In line with the specifications, the flux-proofed type is suitable for clean environments, whereas the plastic-sealed type is recommended for industrial settings containing pollutants such as H₂S, SO₂ and NO₂, in order to enhance long-term reliability.
Ultra-Compact and Convenient Design
Extremely compact: With dimensions of just 21.5 mm × 16.0 mm × 20.6 mm, it effectively saves PCB space and is ideal for high-density circuit board designs.
Standard PCB pins: These facilitate automated placement and soldering, thereby improving production efficiency.
Rapid switching response: With an operation time of ≤15 ms and a release time of ≤10 ms, it ensures a swift response.
Extended Mechanical and Electrical Life
Mechanical durability: It withstands up to 100,000 operations thanks to its robust and reliable mechanical structure.
Electrical Life: At room temperature, withstands 10,000 operations under rated load (32A, 250VAC) with a duty cycle of 1 second on/9 seconds off, meeting the life requirements of most applications.
Industrial control includes solenoid valve control, variable frequency drives, motor drive controllers, and programmable logic controllers (PLCs).
Home appliances: High-powered air conditioners, water heaters, washing machines and other kitchen appliances.
New Energy & Power Supplies: Photovoltaic inverters, charging station modules, uninterruptible power supplies (UPS), switching power supplies.
Automation Equipment: CNC machine tools, packaging machinery, robotic control systems.
Model Example: FH14T-E - IA - Nii - T - DC24V
