2 Application and short description STW1K current relay is an automatic starting device in OR circuit with 8 inputs. If a current > 1 A flows through at least one connected transducer, the integrated relay (1co) is activated. If the currents through all transformers are 0, the relay switches off with a delay of about 10 s to allow for the necessary timeout, e.g. -

5 Detailed description The STW1K current relay operates in an OR circuit and detects whether or not current is flowing in one of up to 8 monitored wires. The relay is activated when the current flowing through the current transducer exceeds a value of approximately 1 A. -
Page 4: Important Information
• connecting wires refer to the connection plan to prevent miss-operation and malfunction. A circuit-breaker or switch must be situated within easy reach of the unit and fused. Installation excess current protection should be ≤ 10 A. STW1K 10630-0721-00 Page 4 / 8... -
