A circuit breaker must ensure to trigger breaking when during running current is suddenly increased

It should not trigger during motor start where current is actually very high

A sudden increase in current from steady state means audden load increase which could be something struck in conveyer belt

Thanks. Just used DC breaking to test a motor at work to verify we've got the correct fuse values. Worked great.

seeing is believing.I like the fancy DC braking available for load torque similation for steady-state app.

I'm no electrical engineer, but is the answer to the end to hook up a fuse on a delay to kill the circuit if its over the operating amperage? ie. two wires from power (one with a fuse, and the other with no fuse) to the motor but after reaching steady state, the no fuse circuit disconnects?
