FAQ

Q: How to apply for samples? What is the lead time?

A: You can submit a sample application through our website or email. Samples are free of charge and will be shipped within 3-5 working days. Mass order lead time is generally 2-8 weeks; custom products will be confirmed separately.

Q: Do you support small trial orders?

A: Yes. Small trial orders (below the standard MOQ) can be negotiated and receive the same quality standards and delivery commitments as mass orders. Please contact our sales team for details.

Q: What is the significance of the split-core design for current measurement applications?

A: The split-core design allows non-contact measurement and can be installed without disconnecting the primary conductor. It supports live-line operation without affecting the customer's normal use. The compact size and lightweight design make installation convenient, suitable for rapid deployment in applications such as electrical lines, motors, and relay protection.
