Tronic Motor Protection Circuit Breaker 20-25A SGV2-M22

Our review

This Tronic device is a motor protection circuit breaker rated for the 20 to 25 amp band, sold under the model reference SGV2-M22. Its job is narrow and important: it trips when an electric motor draws too much current or when a short circuit occurs, which helps prevent the motor winding from burning out. It suits anyone running a three-phase or single-phase motor on a machine, pump, compressor or workshop tool where an unexpected fault would be costly. Before buying, confirm the motor's full-load current sits inside the 20 to 25A range, since a breaker sized too low will nuisance-trip and one sized too high will not protect properly. Also check the mounting style and terminal layout match your existing panel. Compared with a plain thermal overload relay, this type combines overload and short-circuit protection in one unit, which simplifies wiring. Compare adjustable range, breaking capacity and trip class against other breakers of this size, and note that no further specifications are listed here, so verify them on the Sokonia listing before ordering.
