Abstract
A hall effect current sensor including a mounting bracket, a sensor assembly, and a sensor core. The sensor assembly includes a flux sensor. The sensor core includes a first portion and a second portion. The first portion and the second portion define a first air gap and a second air gap between the first portion and the second portion. The first air gap is adapted to receive the sensor assembly.
