Latching Switch Relay Maintains Multiple Contacts

Designed for the electric power industry, the Series 24 and 31 latching switch relays (LSRs) are used to open or close and maintain up to 20 contacts and can be operated either manually or remotely. 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. The switch relays have a blade-and-terminal design and can control of up to 40 independent contacts in a single device. Designed to withstand vibration, the LSRs are a two-position, rotary-action device compliant with UL, CSA, and ANSI/IEEE standards for Class 1E utility products. A choice of three coil voltage ranges are available: 38 to 56, 100 to 140 and 200 to 280 Vdc. ELECTROSWITCH, Weymouth, MA. (781) 335-5200.
