  • Description

The ABB 7TCA085400R0353 (OVR 30E) is a single-pole DIN-rail surge protective device for 30 V data and signal lines, built for continuous operation up to 37.1 V. It handles a maximum discharge current of 10 kA (8/20 µs) and limits the voltage protection level to 43.5 V, shielding signal circuits carrying up to 300 mA from transient overvoltages caused by lightning and switching events.

Selection Notes

With a single protected pole and a 300 mA rated current, the OVR 30E fits one 30 V signal pair where only one line pair needs transient protection. Its 1 Ω series resistance keeps insertion loss low on sensitive instrumentation loops, and the 43.5 V protection level clears the 37.1 V continuous operating voltage without clamping the signal itself. Screw-clamp termination with a 6 mm stripping length matches standard field wiring without a separate connector kit.
