Due to their high breaking capacity with high current limitation, MS Guardamotors provide optimum protection for motors Electric, as well as other applications up to 25 amps. They are equipped with a device for sensitivity to phase failure, insulation and Mainly switch functions, 13 nominal current ranges cover 0.1 to 25 amperes.

Up to 100kA can be obtained from rupture if used with Cat current limiters. SBMS32. The MS guardamotors are automatically Compensated against variations in ambient temperature; The operation of the short-circuit breaker is 12 x lu. The Warners MS are in accordance with IEC 947.
