The Nittan EV-DIN-SCI (part no. F03-83620) is a DIN rail mounting short circuit isolator for Nittan Evolution analogue addressable systems. It fits a standard EN 50022 DIN rail, with cable connections via terminals at each end.
It is made for dry, clean areas but can be fitted inside a protective enclosure for harsher environments. The isolator works transparently with no settings needed, resets itself when the fault clears and has a short circuit indicating LED. Nittan notes that +ve and -ve isolator styles cannot be mixed on one system, so check panel compatibility with Nittan technical support.
