Abstract
A mounting bracket for a circuit breaker air-core coil includes a unitary body having a generally U-shaped body. The body has at least one retaining form structured to fit over a fastener head. When installed in a typical power air circuit breaker, the air-core coil disposed in the mounting bracket is located above the circuit breakers's load conductor fasteners. These fasteners, and therefore the air-core coil, are located outside of the space in the circuit breaker occupied by a current sensor.
