Danfoss CI 6 - CI 50 Contactors
CSE's Southampton branch is a Danfoss Low Voltage partner with an extensive range of Danfoss stock. Ray Hargreaves and the team also have specialist Danfoss knowledge and training to assist our customers with their enquiries.
The contactor programme CI 6-50 is based on three frame sizes. The smallest frame size consists of CI 6-15 (2.2-7.5 kW), the middle contains the CI 16-30 range (7.5-15 kW) and the largest frame size is represented by the CI 32-50 (15-25 kW). All frame sizes are provided with three NO main contacts. CI 6-15 are available with four NO main contacts.
A long electrical lifetime makes the CI 6-50 contactors suitable for operation of all kinds of electrical loads in modern industry. Combined with a thermal overload relay, the contactor switches and protects induction motors against overload and asymmetric load.
A wide range of clip-on aux. contacts, timers, surge suppressors, mechanical interlock and marking plates makes the CI 6-50 programme very flexible and suitable both for OEMs and panel builders.
- Compact design in three frame sizes
- Screw or DIN rail mounting
- Power range 2.2 to 25 kW
- For ac coil voltages

1) Coil voltage / frequency or Suffic no (see table below) must be added to the Danfoss code no.
2) AC-15 operation : max. 500 VA/6 A
3) Ue max. : 500V
4) The thermal current value Ith gives the maximum load at 40oC, which corresponds to installing the contactor in air (open)
5) The thermal current value Ith gives the maximum load at 60oC, corresponding installing the contactor inside an enclosure
6) Heat -resistant leads (min. 75oC) must be used.
