VCF is a range of switch disconnectors fuse suitable for making and breaking on load and disconnecting low voltage electrical circuits. They are commonly used for the following purposes:
• main switch
• switch for motors
• disconnector
• safety switch
They are available in 4 sizes and 5 current ratings.
GENERAL CHARACTERISTICS
• rated insulation voltage 1000V AC and 1500V DC
• 3-4 poles available
• high breaking capacity (AC-22, AC-23, IEC 60947-3)
• high electrical and mechanical endurance
• four break contacts
• self cleaning contacts
• both fuse terminals are not alive when the switch is in O position
• suitable for DIN, BS and NFC fuses
• contact position positively indicated by the handle
• visibility of fixed and moving contacts by means of windows
• independent manual operation
• neutral contact makes earlier and opens later than the phase contacts
• solid neutral version available
• suitable protection to prevent accidental touching of live parts
• casing in self-extinguishing (V0-UL94), low hygroscopic and high mechanical resistance isolating material.
• resistant to damp heat (IEC 68-2)
• wide range of accessories
• rotary front operation by means of: external double insulated handle with door-interlock in ON position, IP65 degree of protection. Padlockable with three padlocks in OFF position
• direct handle (padlockable in OFF position on request).
