Tronic Motor Protection Circuit Breaker 13-18A SGV2-M20

Our review

This Tronic device is a motor protection circuit breaker, a component that sits in a control panel and trips when a motor draws too much current, loses a phase, or short-circuits. The 13-18A setting range makes it relevant to small and medium three-phase motors, such as those on pumps, compressors, conveyors and workshop machinery. It suits electricians, maintenance teams and anyone assembling or repairing a motor starter who wants protection built into the circuit rather than relying on a general-purpose breaker. Before buying, confirm your motor's full-load current falls inside the 13-18A band and that the trip class and mounting suit your panel; the listing gives no further specifications, so check the motor nameplate and your wiring diagram first. Compared with a plain miniature circuit breaker, a dedicated motor protection device responds to phase loss and overload in a way that better matches motor duty, while a full starter with contactor adds control functions this unit does not provide. Match the range to your motor and treat it as one part of a properly designed starter.
