How to Specify the Appropriate Model
*MOV modules are typically one module per phase and may be wired L-N, L-G or N-G.
**Gas Tube modules typically used in the N-G mode for type TT grounding systems.
***Certain applications require higher rated components in order to survive frequent
voltage rises, in this case order a unit with a “Q” at the end of the part number.
Replacement modules available: Order DRS + U
n
+ M (for MOV) or G (for Gas Tube)

DRS Series
The DRS is a modular surge protective device (SPD) that is designed for easy
installation in control panels using standard DIN rail mounting brackets. The DRS
devices offer both normal and common surge protection up to 40 kA per phase.
