CT Current Transformer Prototyping Kit
Eight nanocrystalline toroid sizes for current transformer and sensing R&D. Two of each size so you can wind one and keep a spare while you compare Ae, window, and magnetizing inductance.

Who it's for
- Current transformer design engineers
- Metering and protection R&D teams
- Gate-drive and sensing prototype labs
- University power-electronics labs
Typical use cases
- Metering and protection CT size selection
- Gate-drive transformer prototyping
- Ground-fault and residual-current sensing trials
- Benchtop current-sensing experiments
How to use
Start with the 20 mm or 25 mm core for most small CTs. Step down to 16 mm when board space dominates. Move up the ladder when you need more window for heavier wire, more VA, or a larger pass-through ID. After you lock a size, reorder that single SKU in production packs.
FAQ
Who should buy the CT Current Transformer Prototyping Kit?
Design engineers and labs selecting nanocrystalline CT or sensing cores who want several nearby sizes on the bench before locking a production SKU.
How many cores are in this kit?
Sixteen PBT-cased nanocrystalline toroids: two of each of eight sizes from 16 mm to 50 mm OD.
What happens after I pick a winning size?
Reorder that single catalog SKU in pack quantities (or request a production-gapped cut core). Kits are for size and gap exploration, not a substitute for locking a production part number.
Do kits ship with datasheets?
Each included SKU has its own product page with dimensions, AL, and photos. Open the linked part numbers in the contents table for datasheets and specs.
