Product Description

Model 880B AC Current Level Detector provides an effective and accurate solution to monitor AC current. A conductor wire is routed through a ¾ inch hole which provides non-intrusive and isolated means to measure desired current. After the measured input current reaches the set trip point, the relay trips and an indicator LED light is illuminated. A precision internal reference guarantees repeatable operation.

The 880B AC Current Detector has an input current range from 2Aac to 250Aac, with a frequency range from 50 to 400Hz.  The unit delivers performance accuracy over a temperature range from -20°C to +70°C and are “self excited”, requiring no power to operate.  The adjustable trip point makes the detector adaptable for many applications. The 880B comes standard in a plastic molded housing with a barrier interface.
