Depending on the size, and in particular on the central hole for passing through cable (or copper bar), there are four current transformer families, called 150, 151, 152 and 153, with pins or faston connection. Typical working temperature is from -40 to +70°C. The plastic material of the case is UL94-V0.

Our proven Technology
Mains frequency current transformers are used to measure alternate currents at 50-60 Hz, up to 600 Arms.
They are based on toroidal Silicon Iron core; they typically have a high number of secondary turns, so that the secondary current is relatively low. By connecting a burden resistance to the secondary side, you can read a proportional voltage signal, isolated from the mains. As the secondary current is low, the low power burden resistance can be connected to the PCB.
