Split-Core Current Transformers
Short description:
WAGO's compact split-core current transformers are ideal for retrofit applica-
tions in existing systems. They are particularly suited for applications in which
the current path may 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 secon-
dary cable. All transformers are supplied with color-coded cables. Two
UV-resistant cable ties for reliable and easy mounting are also included.
Features:
• Current ratios from
60 A up to 1000 A (primary side) and
1 A or 5 A (secondary side)
• No interruption of the measuring cable
• Ideal for use in very confined spaces
• Superfast mounting
• For use around insulated cables up to Ø 42 mm
• Compact and hinged
• Color-coded connecting cables up to 5 m
