Product Q&A

Q: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

Q: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.

Q: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.

Q:How long does it take to receive the goods after payment?

After full payment, all goods will be sent to you in 6-10 days as usual. For orders lower than 1000PCS that are not customized, 3.5 days delivery is available upon receiving payment.

Q:What is the warranty period for this product?

We provide a 1-year warranty. If the product is defective, please notify us within 3 days of delivery. All products must be returned on their original condition to qualify for a refund or exchange.
