CDC17 series AC contactor is designed for long-distance making and breaking in circuit, frequently starting and controlling AC motor in the power system with frequency 50Hz/60Hz, rated insulation voltage up to 690V and rated operating voltage to 380V in Category AC-3. It also can be assembled with CDR7 or other thermal relay or electrical protection apparatus, as electron magnetic starter, to protect circuit against overload or phase breaking. It can also be used in the circuit with rated operating voltage of 660V when lowering adequate current.

National Standard: GB14048.4
International Standard: IEC 60947-4-1

1. Ambient temperature: It works within-5℃～+40℃, and the average temperature no more than +35℃ in 24 hours.
2. Altitude: No more than 2000m.
3. Atmosphere: Relative humidity no more than 50% at max.40 ℃, and it may be higher at a lower temperature. The lowest average temperature no more than 25℃ in the wettest month. The maximum average relative humidity of this month doesn't exceed 90℃. The change of temperature leading to dew on the product must be considered.
4. Mounting condition: The inclined angle between the mounting surface and the vertical surface no more than +22.5°;Contactor can be installed 35mm (no more than 32A and 115A、150A) type standard guideway by screwdriver.

1. Small volume, light weight, less power-loss, long life span and beautiful feature
   2. shell is adopted excellent fire-resisting insulated material ,which can withstand high temperature and is safe and reliable
   3. Can be assembled with various components that were designed into module to extend its functions. The auxiliary modules installed in front side are: CDF4 auxiliary contact group, CDLA2, CDLA3 air time-delay head; that in lateral side are: auxiliary contact group and mechanical interlock.
   4. Can be connected with CDR7 (95 and below) and CDRE17 (125 and below) series thermal relay into electromagnetic starter without any connect-ing wire.
