Surge protective device are designed to provide application specific surge protection for factory automation and industrial control devices. ABS case. Plated steel ground tab. 9.6 VDC voltage rating. -40 to 60°C operating temperature. -4.5 to 4.5 V maximum DC operating voltage. 12 Vpk clamping voltage. 1 kA maximum surge current. With 3-pin header connector, surface mount. Surge protection devices can be used individually or as part of a coordinated application strategy, to protect sensitive electronic equipment, in industrial, commercial and residential locations, from the stress and degradation inflicted by voltage transients. Leviton's outstanding surge protection devices divert damaging voltage transients or surges, away from electronic equipment. Transients are diverted away from sensitive micro circuitry, providing protection against catastrophic failure, costly downtime and data disruptions. Used for devices operating on Allen-Bradley 4 to 20 mA signal loop networks and other related protocols, 9 V.
