Is a range of switch disconnectors 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 6 sizes and 20 current ratings.
GENERAL CHARACTERISTICS
• rated insulation voltage 1000V AC and 1500V DC
• 3-4-6-8 poles available
• high breaking capacity (AC-22, AC-23, IEC 60947-3)
• high electrical and mechanical endurance
• double break contacts
• self cleaning contacts
• 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
• neutral at full current until 1250 A, standard, 1600 A ÷ 3150 A on request
• suitable protection to prevent accidental touching of liveparts
• casing in self-extinguishing (V0-UL94), low hygroscopic and high mechanical resistance isolating material
• resistant to damp heat (IEC 6068-2)
• 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).

NORMAL SERVICE, MOUNTING AND TRANSPORT CONDITIONS
• storage and transport ambient temperature - 25°C + 55°C
• working ambient temperature - 20°C + 45°C
• in case of higher ambient temperature (ta) consider the following derating formula:
• relative humidity max 95%
• rated frequency 50-60Hz
• altitude max 2000 m a.s.l.
• pollution degree 3 according IEC 947-1
• can be mounted in any position
• mounting in enclosure:
in case of utilisation at full load and without adequate
ventilation, ensure a volume of about 5 times the volume
of the switch.
• duty (IEC 947-1):
eight-hour; uninterrupted; intermittent 60% class 30;
temporary; periodic
For other operating conditions contact the manufacturer.
N.B.
Standard shaft lenght 200 mm included into the package
* For solid neutral switches add “SN” to the code of corresponding four pole switch
* For full current switches (standard until 1250A) add “FN” to the code of corresponding four pole switch from 1600A onward.
