I am using Omron G5RL-1A-E-HR relay in my project with these specs:
I am using the high inrush type with max allowable current of 16 amps. I have used with water heaters up to 2 kW and air conditioners rated approx 2000 VA. Good thing about air conditioners is that they have a stabilizer which also delays the turn on of air conditioner. As such, there is no risk of high inrush current. However I am not sure if I turn it off when the air conditioner is running. Anyways, I haven't seen a failure in almost an year.
What's the max hp pump that I can put on this relay for a reliable operation? This case is different from air conditioner because motor will pull current as soon as I turn the relay ON. Do I need to make any changes to the circuit to improve it's life?
