IDEC introduces RSC relays with the technology to dissipate heat away from main switching components. These new RSC relays incorporate a built-in heat sink, which facilitates installation and setup. An LED status indicator makes sure users can see the relays working. The relays' slim design provides a compact unit for DIN rail or panel mounting without wasting space. While 20A and 30A current ranges are 22.5 mm, the relays with 45A current are 45 mm. All RSC relays are UL and c-UL listed, CE marked, in addition to lead-free and RoHS compliant.
