Sizing snubbed MOV for pump motor.
(1/1)
JustMeHere:
I want to control a 240v 8A AC watre pump motor with a relay.  My research suggests I use a MOV to protect the relay contacts.  I can't figure out which MOV to use. 

Thanks in advance for any help.
T3sl4co1l:
Very little energy is required, compared to the energy a MOV can handle.  A 7mm dia. THT, or 2820 size SMT chip, will do.  Maybe even a 1206 or 1806, if they make one in that voltage.
