  • Description

The ABB 7TCA085400R0383 (OVR SL30/I) is a slim-line, 4-pole surge protective device for 30 V signal lines carrying up to 750 mA, with an isolated screen connection for shielded cabling. It discharges up to 10 kA (8/20 µs) and holds the protection level to 45.4 V, guarding multi-wire data circuits against lightning and switching transients.

Selection Notes

Four protected poles let the SL30/I cover a full shielded 4-wire line plus isolated screen in a single slim housing, rather than stacking single-pair modules. The isolated screen connection keeps cable shield grounding separate from the signal-line earth reference, which matters on installations where screen and chassis ground are not at the same potential. At 7 mm thick, the slim-line body saves panel width on cabinets already packed with other DIN-rail protection.
