The M series starters are composed of a contactor and thermal relay. To protect it against short circuits it is recommended to use fuses to be chosen according to the thermal overload relay current range. In the chapter of the catalogue dedicated to thermal relays are indicated, next to each code, the aM or gG type fuses that provide the correct protection. For those who want a complete starter with overload and short-circuit protection, we remind the version M2P00911…. that, in addition to the contactor, have a motor protection circuit breaker of the SM1R series inside.
