  • Description

The ABB 7TCA085400R0341 (OVR 30Q) protects 30 V, 8-wire (4-pair) signal lines with a space-saving single-module DIN-rail design. It carries a 750 mA rated current, clamps transients to a 43.5 V protection level, and discharges up to 10 kA (8/20 µs), guarding multi-pair data cabling against lightning and switching surges.

Selection Notes

The 8-wire (4-pair) protection scheme covers a full multi-pair signal cable on one device instead of wiring four single-pair units. Its 750 mA rated current and 6 MHz rated frequency suit higher-pair-count data buses without materially loading the line, and the 37.8 V continuous operating voltage leaves headroom below the 43.5 V protection level for a nominal 30 V system. Screw-clamp terminals with an 8 mm stripping length keep field wiring consistent with other OVR data-line models.
