Enclosed Pilot Relays
The Pilot Series contains relays that are rated at 10 or 15 Amps. They have been packaged to save the installer the time, trouble and expense of buying separate components (relay, LED indicator, socket, mounting rail, transient protection and housing) and assembling them on the job or at the shop.
