DRA Series

AC Power DIN-Mounted SPD with Replaceable Mods

The Meter-Treater DRA Series of Surge Protection Devices (SPDs) are single pole, parallel connected (MOV based technology) Type 1 CA (component assembly) protectors. Designed for use in both Type 1 and 2 locations these units are ANSI/UL 1449 Recognized. Each protector module provides 50 kA of Surge protection in a maintenance free, standard DIN profile, DIN Rail mountable, IP20 enclosure.

Benefits

  • DIN Rail mountable surge protection devices

    • Replaceable SPD modules eliminate costly, time-consuming replacement wiring ?

    • Simple snap "in/out"design for module replacement ?

    • Compact & lightweight yet rugged

  • Visual monitor advises protection status

  • Model choices allow for single mode or all-mode protection strategies

  • Each protector module's fixed base is "keyed" to ensure proper application

  • All protectors (except N-G model) are equipped with signaling contacts for remote monitoring of protection status

The DRA Series is extremely flexible and can be configured to meet your exact protection requirements. A combination of base options allows for increases in per phase or per mode surge capabilities by simply ganging units.
