CT-0.72 LRG
Current Transformer
NIK CT-0.72 current transformer in medium-sized LRG housing is designed for accurate current signal transmission in AC installations up to 0.72 kV.
Built to handle higher currents, it is suitable for systems requiring stability, wide compatibility, and long-term maintenance-free operation. It performs reliably in demanding conditions with operating temperatures from -45°C to +40°C and supports installation in any position.
The transformer offers over 300,000 hours of operational life and a 16-year calibration interval.
Fully compliant with LVD 2014/35/EU and RoHS 2011/65/EU directives.
Manufactured according to EN 61869-1:2009, EN 61869-2:2012, and EN IEC 63000:2018 standards.
