The SCTK660B series split-core current transformer is designed for power monitoring,
energy management, and retrofit projects. The product uses a
flip-open split-core structure that allows quick installation
without disconnecting cables, making it especially suitable for
retrofit projects and online installation scenarios.It offers
high-precision measurement. Isolation voltage is 3KV/60 seconds.
The flame-retardant housing meets UL94V-0 standards. Maximum
working voltage is AC600V.It is widely used in data logging, power
monitoring, energy management, new energy monitoring, and cost
allocation applications.

FAQ
Q: Does the split-core current transformer require power-off during
installation?
A: No. The SCTK660B series uses a flip-open structure with a core that opens and closes. It
can be installed without disconnecting or removing any cables. It
is especially suitable for retrofit projects and applications where
power cannot be turned off.
Q: What is the significance of the UL94V-0 flame-retardant housing?
A: UL94V-0 is one of the highest standards for plastic material
flame retardancy. It ensures the sensor housing is not easily
ignitable under abnormal conditions, meeting the safety
requirements of industrial equipment.
Q: How to apply for samples? What is the lead time?
A: You can submit a sample application through our website or
email. Please provide your company information and target model.
Samples are free of charge and will be shipped within 3-5 working
days. Mass order lead time is generally 2-8 weeks.
