Product Description

Dp Series Clamp-on CT Split Core Current Transformer for Switchgear
DP Series retro-fit split-core current transformer have been specifically designed to be easy to open and yet maintain the accuracy required for intelligent meters, quick to fit around cables. An internal precision resistor across the secondary winding of the CT provides a low safe voltage output. It can be placed into position easily and without disturbing or disconnecting the main cables it it monitoring.


1) Double-screw fastening, safe, easy to install, portable

2) Two built in fixing methods: Base; Busbar mounting

3) Wide inner window, allowing clamping of big cables or bus-bars

4) Wide range of sizes to accommodate all the existing installations.

5) Primary current from 5A to 5000A

Dp Series Clamp-on CT Split Core Current Transformer for Switchgear


1) Current measurement, monitoring and protection for electrical wiring and equipment.

2) Current and power measurement for electric motors, lighting, air compressor, heating

and ventilation system, air-condition equipment and automation - control system.

3) Current, power and energy monitoring device.

1) What is the difference between a moulded case current transformer and a split core current transformer?

A moulded case current transformer is a solid ring of steel in a plastic or resin case and can only be used when you fit the cable through the hole in the middle of the plastic/resin case.
A split core current transformer is manufactured with the steel core in two pieces. This enables the core to be separated, allowing you to fit the cores around the cable without disconnecting the cables. The disadvantage with split core current transformers is that they can be larger than standard moulded case and the price is approximately four times more expensive.

2) Which way round do the Current Transformers go?
The current transformers must be fitted and connected in the correct way or the meter will not be accurate. The current transformers are marked on two sides: 'P1' and 'P2.' 'P1' must face the mains side and 'P2' must face the load side. 'S1' must be connected to the main side of the meter and 'S2' to the load side. Refer to appropriate wiring diagram of the meter for correct connections.

3) Can the current transformers be a higher or lower ratio then my maximum load?
The current transformers should ideally be about 80% of the normal running load, thus allowing a 20% allowance of increasing the load in the future.
