● Closed loop (compensated)current transducer● Insulating plastic case recognizedaccording to UL 94-V0.

Advantages● Low temperature drift● No insertion losses● High immunity to externalinterference● Current overload capability.

Application● Leakage current detection.

Note: Delay time is measured when the residual current moves from 0 to		 threshold level. If the starting value of residual current is > 0 the delay		 time will be reduced.
1)● Railway (fixed installations andonboard).

SafetyThis transducer must be used in limited-energy secondary circuits according toIEC 61010-1.

This transducer must be used in electric/electronic equipment with respect toapplicable standards and safety requirements in accordance with themanufacturer’s operating instructions.

Caution, risk of electrical shock
When operating the transducer, certain parts of the module can carry hazardous
voltage (e.g. primary busbar, power supply).
Ignoring this warning can lead to injury and/or cause serious damage.
This transducer is a build-in device, whose conducting parts must be inaccessible
after installation. A protective housing or additional shield could be used.
Main supply must be able to be disconnected.
