Frequently Asked Questions (FAQ)
1. What are the installation structures of the CJX8 series AC contactors?
CJX8-30 and below adopt a "normal installation structure" (contact system at the front, magnetic system at the back). CJX8-37 and above adopt an "inverted structure" (magnetic system at the front, main contact system at the back).
2. Is it necessary to disassemble the main conductor when replacing contacts for CJX8-105 and above?
No, it is not necessary. For CJX8-105 and above, the main static contact can be separated from the main wiring, which eliminates the need to disassemble the main conductor when replacing the contact.
3. What arc extinguishing methods are used in the CJX8 series contactors?
The CJX8-9~CJX8-25 models use enclosed natural arc extinguishing; CJX8-30~45 models use ferromagnetic sheets; and CJX8-65 and above models adopt ferromagnetic grids. All these products utilize arc-resistant plastic arc chambers.
4. Can CJX8-9 to CJX8-30 AC contactors be mounted on standard rails?
Yes, CJX8-9~CJX8-30 AC contactors can be quickly installed on 35mm installation rails conforming to IEC standards.
5. Which international and national standards do CJX8 series contactors comply with?
They conform to several executive standards, including IEC60947-4-1, VDE0660, NFC63-110, NBNC63158, CE117-3, BS5425, NE50012, and GB14048.4-2003.
6. What is the rated insulation voltage and available coil voltage options for these contactors?
The rated insulation voltage is 690V. The available AC coil voltages are 24V, 36V, 48V, 110V, 127V, 230V, 400V, and 415V, while the DC options are 24V, 48V, 110V, and 220V.
