SWITCHES DISCONNECTORS – SD

_GENERALITIES

The modular switch disconnectors of SD series, allow the breaking and the disconnecting on load of equipment on low voltage at nominal current from 16 to 200 A.

_USE

The switch disconnectors of SD series are commonly used
for the following purposes:

• Main switch
• Switch for motors
• Disconnector
• Safety switch

_GENERAL CHARACTERISTICS

• High breaking capacity (AC 22 A – AC 23 A)
• Double break contacts on each pole
• High electrical and mechanical endurance
• Resistant to damp heat
• IP20 degree of protection (with accessory)
• Modular execution, basic mounting on 35 mm DIN rail and
• by screws, modular window 45 mm.

_RANGE

• SD1 three poles 16 – 25 – 32 – 40 – 63 A
• SD2 three poles 63 – 80 – 100 – 125 A
• SD3 three poles 100 – 125 – 160 – 200 A

_ADDITIONAL POLES

• Fourth neutral pole makes erlier and opens later than the phase contacts.
• Fourth pole solid neutral.
• Earth pole. Contemporary pole under request.

_OPERATING MECHANISM

Black (standard execution) or emergency direct handle padlockable in 0 position. Handle with door interlock handle, black or emergency handle padlockable with up to three padlocks in 0 position.
IP 65 degree of protection.

_STANDARD SERVICE, MOUNTING AND TRANSPORT CONDITIONS

Transport and storage ambient temperature – 25°C + 55°C
working ambient temperature – 20°C + 40°C
in case of higher ambient temperature (ta), consider the
following derating formula:

altitude max 2000 m a.s.l.
pollution degree 3 according IEC 60947-1 duty (UNI EN 60947-1):
8 hours; uninterrupted; intermittent 60% class 30
For other operating conditions please contact the manufacturer.
