CITEL M50s compact, low profi le surge protectors are designed to protect local distribution panels, OEM control panels, PLCs, and SCADA systems against transient surge events.
These devices are installed parallel to the AC network and provide robust surge handling capability. The M50 is available up to three phase applications and is rated at 50kA (8/20?s) transient amps per phase.
