Questions Buyers Ask
What ratios are available on the PCB range?
The catalogue lists ratios such as 5 A/2.5 mA, 5 A/5 mA, 10 A/4 mA, 10 A/5 mA, 10 A/10 mA and 20 A/20 mA across the CT-226B, CT-406 and CT-407 bodies. Send the meter input and the ratio you need and an engineer will confirm the part.
Can the transformer be customised?
Yes. Customer specifications are available, including turns ratio, lead length and case.
Does it work above 50 Hz?
Working frequency is 50 to 400 Hz, so it suits aviation and variable frequency applications as well as mains metering.
Is it suitable for DC immunity applications?
The published page describes this body as a PCB mounted type without DC immunity. Tell us if DC immunity is required and we will quote the correct core.
