300A Split Core Current Transformer (including Fly Lead)

Split Core 35 mm Diameter Aperture | 300 A Primary | 2 m Fly Lead (2.5 mm² Wire) | Accuracy Class 1
These clip-top, split-core transformers work with any 5 A CT-operated meter. No need to break conductors—simply clamp around a single live conductor. Use one per phase for three-phase systems. The 35 mm opening fits up to 35 mm conductors, making it ideal for distribution boards, generator sets, control panels and switchgear.
