Re: Varistors - help

["Frank Mc Alinden" <fmcalind@xxxxxxxxxxxxxx>]

Hi Paul
If the solenoid is quite hefty might need  to use a industrial
type suppressor ...got one here its a  MURR Electronics (25180) device 24v
ac/dc..........used for 24v contactors...would be able to get something
similiar from an electrical wholesalers but wont be cheap.......

HTH
