Description

current transformer 250/5 A, 5 VA CL 1.0 4NC bushing type current transformer The bushing-type current transformers are used for primary rated currents of 40 A to 3000 A, secondary rated currents of 5 A or 1 A and in the categories 0.2S, 0.5 and 1. They are also suitable for measurement functions with PAC and AI Energy Meter thanks to better accuracy, and are employed in the mechanical engineering sector most commonly for new systems with mid-range power ratings and in plant construction. www.siemens.com/switching-devices. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, distribution systems as well as switches and sockets for safe and efficient electrical infrastructure in buildings and industry.
