WebCircuit Breaker Curves The following curve illustrates a typical thermal magnetic molded case circuit breaker curve with an overload region and an instantaneous trip region (two instantaneous trip settings are shown). Circuit breaker time-current characteristic curves are read similar to fuse curves. The horizontal axis WebSo in case of a magnetic circuit breaker, a solenoid or an electromagnet is attached to the trip unit. The function of the solenoid or the trip unit is to generate amagnetic field. This is done when the current passes through the solenoid, magnetism develops in it due to changing magnetic flux, and a magnetic field is created around the solenoid. tssaa high school basketball
