Rayleigh Instruments - CT240-EW - Easywire current transformer - aperature

Product Description

This three phase current transformer is suitable for monitoring current in industrial and commercial applications and is designed to connect to the easywire® series of metering products.

Built-in limiting circuitry ensures the secondary of the current transformer is always under load and clamped to a safe level. This means that the output connection may be safely disconnected while under load.

Improved design features of these easywire® current transformers include a robust ‘snap-on’ DIN rail fixing, captive busbar location screw fittings, insulated busbar location feet, sealable (anti-tamper) RJ45 connection sockets and moulded load direction indication arrows on the CT shoulders.
