Motor protection circuit breakers

Transcription

1 R Motor protection circuit breakers Motor protection circuit breakers are used for start-up and protection of electric motors (industry, small machines, external use, agricultural machines, compressors, repair shops, etc.).

2 Motor protection circuit breakers are a special type of circuit breakers designed for protection of wide range of single-phase and three-phase C motors against overload and short circuit. For motor protection: ll kind of C induction motors For three-phase motors up to kw Protection of other loads: Various low-inductive loads Version for single-phase consumers Version for transformer protection Version for short-circuit protection Other benefits: Wide range accessories Mounting on 5 rail Horizontal or vertical operating position Motor protection circuit breakers MS up to... page Motor protection circuit-breakers MS8 up to 8... page ccessories for MS, MS8... page 4 Motor protection circuit breakers MS up to... page 7 ccesories for MS... page 9 ccessories - general... page Ordering data... page, 8 Technical characteristics... page Dimensions... page 4
