The CR9400 Series and CR9480 Series of Normally Closed Current Switches by CR Magnetics have a low fixed trip point and are fully isolated and self-powered.

CR Magnetics’ CR9400 Series and CR9480 Series of Normally Closed Current Switches are designed for applications that require an on-off indication of current flow. The key features include a low fixed trip point as well as being fully isolated and self-powered. These feature allow for lower losses, improved lifetime durability, increased ruggedness and heat capacity.
The CR Magnetics CR9400 Series Current Switches are a closed design while the CR9480 Series are Split Core Current Switches. They are available with a NPN or PNP output transistor for DC switching and ACA output for switching AC. Continuous operating current above the rated full ON level of 350 mA is required.
