Hy, we are using main circuit breakers (with embedded coils) to supply our machines. These breakers are installed inside enclosures. But we had some problems with the cutoff of the power: We used to install a handle with a rotating device on the enclosure door, but our operators are too strong: they use it till breaking after a few months. So we switched to supplying the breaker coil through an emergency stop installed on the enclosure door, and we added to this circuit a phase monitoring relay (to power off in case of supply problems).
Now, we are facing burned breaker coils every few months. We contacted our breakers supplier and they suggested installing a small isolating transformer to supply the coils.
Kindly, does anyone have some suggestions?
(note that we have frequent power failures and perturbations in our country!)
