50-400Hz Instrument Current Transfomer
The GWCTT series from Tianjin Grewin Technology is a single-phase, core-type instrument current transformer designed for 50-400Hz applications in power, electronic, lighting, rectifier, and audio systems. It operates within a frequency range of 50-400Hz and supports an input of 60-4000A with an operating voltage of 600VAC. The transformer features a dry-type cooling method, multi-winding construction, and a PBT or ABS shell, delivering reliable isolation at 600V with a basic impulse level of 10kV.
This instrument current transformer is built with a PCB or wire core shape, ensuring compliance with ANSI accuracy class standards. Typical industry specifications for such transformers include a temperature range of -25 to +70°C, though this model is rated for -25 to +55°C. The outer dimensions for similar units often range from 10-80mm, with this model measuring 12-72mm. Material grades for the shell typically meet UL94-V0 flammability standards, and the windings are usually copper with class B or F insulation.
Common applications include current measurement in power distribution panels, energy meters, and industrial control systems where precise current sensing is critical. Buyers typically source these for integration into switchgear, protection relays, or monitoring equipment. The unit is packaged in export-standard cartons with strong pallets and shipped via express couriers like UPS, DHL, or FedEx, with a typical lead time of 20 days for orders under 1000 units. The supplier offers a 1-year warranty with a 3-day defect notification requirement.

Sourcing 50-400Hz Instrument Current Transformer from Tianjin Grewin Technology Co.,Ltd. - China Import Guide
Before ordering, verify the transformer's compatibility with your system's voltage, current, and frequency requirements. Confirm the accuracy class meets your metering or protection needs, as ANSI compliance may not cover all regional standards. Check the mechanical dimensions to ensure proper fit in your switchgear or panel, especially if space is constrained.
For logistics, confirm the shipping method and lead time, as express couriers like DHL or FedEx typically take 3-7 days, while larger orders may require sea freight. Incoterms should be clarified, as the supplier offers door-to-door delivery but may not cover import duties. Payment terms are 30% deposit and 70% before shipping, with full payment required prior to dispatch. Buyers should also confirm the warranty coverage and defect notification period.
Quality checks should include testing the transformer's ratio, phase shift, and accuracy under load conditions. Request a certificate of compliance for the accuracy class and isolation rating. Inspect the packaging for export-standard cartons and pallets to prevent damage during transit. For critical applications, consider third-party inspection to verify performance against ANSI or IEC standards. Documentation should include test reports, material certifications, and warranty terms.
