Featured product

Solid-State Relays

The relays in this collection are:

  • Normally closed
  • Solid-state
  • Small

Because they're normally closed, impressured current will be maintained and cathodic protection ensured, even if the interrupter loses power. Their solid-state composition means that, compared to their mercury counterparts, they operate with lower control currency, have faster cycle times, and last longer. Plus, each relay is compact enough to be mounted inside most rectifiers.
