What is the Wago 855-4105/400-101?
Short description:
WAGO's compact split-core current transformers are ideal for retrofitting existing systems. They are perfect for applications in which the current path must not be disrupted. The transformer's accuracy permits extremely precise current measurements. The split-core current transformers are capable of supplying the specified rated power at the end of the secondary cable. All transformers are supplied with color-coded cables. Two UV-resistant cable ties are also included for secure and easy mounting.
Features:
Current ratios from 400 A (primary side) and 5 A (secondary side)
No primary cable interruption
Ideal for use in very confined spaces
Rapid mounting
For use around insulated cables up to 28 mm diameter
Compact and hinged
Color-coded connection cable up to 0.5 m
