nt50-miniature-circuit-breaker-1NT50

Application:

  • The circuit breaker is used as a protection switch for power supplying a circuit with AC 50Hz or 60Hz, voltage 220V, current up to 32A. It has inherent overload protection function. Combined with a fuse, it can also provide short circuit protection for a circuit. Besides, it can unfrequently make and break a loaded circuit. It is especially suitable for lighting devices in houses and public places, or a single electric appliance such as refrigerator etc.

sf3-hydraulic-magnetic-circuit-breakerSF3 G3

Application:

  • Hydraulic magnetic miniature circuit breaker are mainly suitable for overload and short circuit protection. It adopts hydraulic magnetic trip instead of bimetal. So it has a high sensitivity and it is also not effected by the ambient temperature. It is especially used for illumination and distribution in industry and commerce. They are mainly used for overload and short circuit protection within the circuit of AC 50Hz/60Hz, rated voltage of single pole or double poles up to 240V, three poles up to 415V. They can also be used for an unfrequent switch-over of the circuit and illumination under normal conditions.
  • Standard: IEC 157-1973.
