The RI-CT248-EW is part of the easywire® family of current transformers and is one of five frame sizes available.

The easywire® system has been designed to save up to 90% installation time compared to a standard current transformer to meter installation.

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.

The RI-CT248-EW is available with a horizontal RJ45 socket (stock) or with a vertical RJ45 socket (to order).

The RI-CT248-EW is available in 3 models with Primary Current : 250A, 400A and 630A.
(All models have easywire® (RJ45) 330mV Output).
