The CR45 series, wire mounted electrical current indicators provide an effective method of monitoring electrical current. The CR series is self powered and is easy to install as it is supplied with a plastic wire tie for installation. They also have a bright yellow case for easy identification. The LED can be red, green, blue, white, yellow, or amber. The most popular application of the CR45 indicator is to provide a method of non-intrusive troubleshooting and status indication of heater elements and motor windings. Panel mounting brackets are available, however, care must be taken when using the CR45 current indicator in heating element applications as the maximum temperature is 85ºC.
