Ningbo Doto Electric Co., Ltd.
The Doto M6-63 3P miniature circuit breaker is designed for three-phase 400V motor and distribution circuits that need simultaneous three-pole disconnection. The three-pole handle mechanism is internally ganged so all phases trip together even on single-phasing faults, protecting motors against phase-loss operation. It uses the same M6 platform ratings: 1-63A, 6kA breaking capacity, B/C/D curves, 690V insulation and IP20 housing, all certified to IEC/EN60898-1 and IEC/EN60947-2.
