Series 24 LSRs can be configured with 3, 5, 8 or 10 decks, with their contacts rated at 60A for one minute and 30A continuously in a range of 125 to 250 Vdc or 120 to 600 Vac. The devices are available with up to three target LEDs incorporated into a traditional nameplate footprint. Series 31 LSRs can be configured with 3, 6 or 8 decks, with contacts rated at 25A for one minute and at 15A continuously from 12 to 125 Vdc or 120 to 600 Vac. Typical uses include latching, reclosing, or as a programming relay for a local or remote SCADA-compatible switch.
