The JQX-105F-2 series of miniature power relays from Xiamen Hongfa Electroacoustic Co. Ltd come with 1-Form-A, 1-Form-B, or 1-Form-C contact configuration and switches at up to 30A current with loads of up to 7.2kVA.

The 32.4-by-27.5-by-27.8mm device weighs 36g and has a nominal voltage of 5Vdc to 110Vdc or 12Vac or 277Vac with 25 ohms to 1.5 kiloohms coil resistance. The coil also consumes 0.9W or 2VA. Initial contact resistance is 50 megohms, while maximum switching voltage is 277Vac or 28Vdc.

The relay has an insulation resistance of 1 gigaohms and a dielectric strength of 2.5Vac between coil and contacts or 1.5Vac between open contacts. Electrical and mechanical lifespan is at least 100,000 and 1 million operations, respectively.
