Relay always turned on?

Hi. Since I haven’tr found any datasheet or some information regarding the Relay, I want to know if I can keep the ri1318 relay about 3 hours powered…

The label say its 10A.

I’ll use always < than 5A for about 3 hours about 4 or 5 times a day.

Have someone some experience regarding this device?

Tks

Should be OK. Are you using bare relay or relay module?

Only Relay with BD139 as a switch and a diode 1N4004 avoind return to the transistor

I'd recommend to use this schematic to reduce power consumption by relay coil.

Thank you.. It is almost your schema... Tks a lot...

My concern is most about if the relay can be powered for long time..(more than 3 hours)

Are you concerned about coil overheating or contacts reliability?

Actually both

When turned on for about 3 hours, its warm... not very hot, but hot.

Warm (below 45 degree C) is OK.

I need to check this to be sure, but I think its not that hot
