Tronic Motor Protection Circuit Breaker SGV2-M21, 17-23A
TSh 60,000
Our review
The Tronic SGV2-M21 is a motor protection circuit breaker built to guard motors against two common failure modes: overloads and short circuits. Its 17-23A setting range means it is aimed at motors drawing current in roughly that band, so the first thing to confirm is your motor's full-load current and whether it falls inside that window. If it sits near either edge, a different frame size may serve you better. Before buying, check the trip class your application needs, the interrupting capacity required by your supply, and whether your panel takes this mounting style, since none of these are stated here. Compare against thermal overload relays paired with separate breakers, which can offer finer adjustment, and against other motor protection breakers in the same current range. The right pick depends on matching the device to your motor and installation, not on brand alone.
