DRS Series - Din Rail Low Voltage Surge Protectors

The DRS Series is a din rail mountable single pair surge suppression module implementing three stage hybrid technology. This module addresses over voltage transients with gas tubes and silicon avalanche components. In addition, sneak currents are mitigated with resettable fuses (PTC's). The PTC's increase resistance several orders of magnitude when overcurrents exceed safe levels. A normal state resumes when overcurrents are removed. The ability self-restore in this manner significantly increases suppressor performance and survivability.

The DRS Series mounts onto a standard 35mm industrial din rail. There are two "Field Side" and two "Electronics Side" screw terminals. Two electrically tied ground terminals are provided for grounding the DRS Series unit to Building Approved Ground.

**For this model only Surge Current: >10, Peak Current: 8kA, Max Continuous Current: N/A; Series Resistance: None.      WARNING: For Discrete Signal Use Only. Do NOT use DRS-130RMS on 120VAC poewr lines. This unit is a Non-Hybrid, MOV design, reated above 5A operational current and can withstand greater than 8 occurrences of a 10kA 8x20Ás waveform and greater than 1000 occurrences of a 200A 10x1000Ás waveform.

5 Blank numbering tabs and 2 Ground tabs are provided with each DRS. Pre-Numbered Tabs available upon request for a nominal charge.
