Direct mea- suring or through current transformer. Owing to the built-in latch function, the ON-position of the relay output can be maintained. Inhibit function can be used to avoid relay Type Selection operationwhen notdesired (maintenance, transitions). The LED's indicate the state of the alarm and the output relay.Throughthebuilt-in shunt it is possible to moni- tor loads up to 5 A AC/DC. 35.5 mm wide housing suit- able both for back and front panel mounting.
