Note on to Conduit (CTC19) (1/2) *: Select one among,, F, and for F. *8: The surge suppressor is an accessory for the lead wire coil. When selecting a coil with terminal box, the surge suppressor is mounted in the terminal box. *9: s standard, the surge suppressor is incorporated in the coil with diode and the 24 VC coil ( 2/), so the surge suppressor symbol S cannot be selected. *: Tropicalization (rust-proof coating) is available as a measure against rust. Contact CK for more information. Note that the tropicalization is not available when the manual override option and the coil option C/// are selected. 0 VC coil is compatible with 0 VC 50/0 z and 1 VC 0 z, and 200 VC coil is compatible with 200 VC 50/0 z and 220 VC 0 z. Note that the coils 5/5M/5N/5I/5J can be used only with 0 VC 50/0 z or 200 VC 50/0 z. For voltages other than above, consult with CK. The lead wire is available in the standard 300 mm length, and 500 mm, 00 mm, 2000 mm and 3000 mm lengths.
