Nevertheless, the specific availability of private molds, 3D software design, and other customization services is unknown.
Product Q&A
Q:What is the difference between a moulded case current transformer and a split core current transformer?
A:
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?
A:
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?
A:
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:What is the warranty period?
A:
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.
Q:What are the shipping options and delivery times?
A:
Products are shipped via UPS, DHL, EMS, FedEx, TNT, etc. 3.5 days delivery upon receiving payment if the quantity is lower than 1000 PCS and it is not customized. Standard express shipping usually takes 3-7 days depending on the destination.
