FAQs
This device is designed as a replacement module for the OVR SL data SPD range and uses a screw clamp connection for robust terminations. It fits three protected poles and aligns with the OVR SL mounting footprint, enabling quick panel upgrades with minimal wiring changes. Follow the OVR SL series installation instructions for torque and wiring guidance to maximize performance and reliability.
Key specs include a nominal voltage of 6 V, Up of 16 V, and Uc of 7.79 V, with In rated at 750 mA and Imax of 10 kA (8/20 µs). These values indicate robust protection for low-voltage control circuits, fast transient clamping, and the ability to absorb substantial surge energy without compromising connected electronics.
Yes. With a 45 MHz rated frequency and three protected poles, the device protects multiple data and control paths in automation networks. Its small footprint and screw-clamp termination facilitate integration into crowded control cabinets, while the replacement-module design minimizes downtime during maintenance or upgrades.
The unit complies with IEC 61643-21 and carries CE DoC, RoHS, and REACH declarations, ensuring regulatory alignment and traceability. It also aligns with WEEE categories for proper end-of-life handling, supporting audits and environmental compliance across global operations.
By preventing transient overvoltages from damaging I/O and power rails, this SPD reduces unplanned outages and component failures, lowering maintenance costs and downtime. Its compact form factor simplifies installation and inspection, while RoHS/REACH compliance reduces regulatory risk, contributing to a favorable total cost of ownership over the system lifecycle.
