The FH52/FH52A is a high performance power relay from FANHAR designed for high load switching requirements. With a switching capacity of 40A and RoHS compliance, the FH52/FH52A is available in a variety of configurations for industrial control, power systems, home appliances and automation equipment.
FH52/FH52A power relays have industry-leading 40A high-current switching capability, and can work stably in 277VAC and 28VDC voltage environments. Its outstanding electrical characteristics are shown in:
Ultra-low contact resistance (≤50mΩ), effectively reducing energy loss
Insulation resistance of up to 1000MΩ to ensure safe isolation
1500VAC/1 minute voltage protection to prevent breakdown risk
Maximum switching capacity up to 11080VA (AC) and 560W (DC)
The relay is manufactured with high quality materials and precision craftsmanship for an extra-long service life:
Mechanical life up to 1,000,000 operations to meet frequent switching needs
Electrical life up to 1,000,000 operations under a 30A load.
AgSnO₂ contact material, anti-arc and anti-oxidation.
Optional plastic sealing structure, dustproof and corrosion-resistant
FH52/FH52A achieves fast response with optimised electromagnetic system design:
Action time ≤15ms, release time ≤10ms.
Precise timing control capability
Stable contact pressure design
Multiple coil voltage options (DC5-110V/AC12-277V)
To meet the needs of different application scenarios, the relay has:
Wide temperature operating range (-45℃~85℃)
