The LxxxR-21 current sensor is a completely new development from GWP, which enables the advantages of sensor technology also for the low voltage area. The design is fitting in existing common housings of CT´s, but with wide range behaviour and lower costs.
Passive technology, no active parts are inside, or a power supply is needed
Standard housings, commonly used in low voltage applications are used, no need of adaptations in switch gears
Wide range behaviour, one sensor can replace thousands of variants of conventional CT´s
