Pollution degree 2 Max. cable size (mm )2 solid wire max. 2x2.5 or 1x4 ; with sleeve max. 1x2.5 or 2x1.5 Dimensions 90 x 17,6 x 64 mm Weight 69 g Standards EN 60255-6, EN 61010-1, RoHS, CE Datasheet Product Datasheet Application Notes Monitoring relay FRI8-05/B serves to monitor current level in single phase AC/DC circuits. Due to its fluent adjustment of release current, it is predestined for applications with necessity of current flow indication, and can be used as precedence relay. Output relay is off in normal state. In case the set current level is exceeded, it switches. Multivoltage supply is an advantage.
