The OVR DIN rail surge protector line is the ideal solution for protecting valuable equipment and keeping an operation up and running.  In an effort to continuously improve the safety of these types of products, UL has issued the 3rd Edition of UL 1449, requiring more stringent testing and modification of the measured voltage protection level.  ABB's OVR is approved to UL 1449 3rd Edition, making it one of the most effective products of its kind on the market today.

In addition to equipment protection, the OVR DIN rail SPDs also reduce downtime related to maintenance and troubleshooting with pluggable cartridges, visual life indicators, and optional integrated auxiliary contacts for remote monitoring.  When a cartridge has reached the end of its life the visual indicator and device wired to the auxiliary contact will alert you to the SPD status. Then simply replace the cartridge, no rewiring is necessary.
