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 200A.

USE
The switch disconnectors of SD series are commonly used for the following purposes:
• main switch
• switch for motors
• safety switch
• disconnector

GENERAL CHARACTERISTICS
• high breaking capacity (AC 22 A - AC 23 A)
• double break contacts
• 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 45mm.

RANGE COMPOSITION
• SD1 three poles for 16-25-32-40-63A
• SD2 three poles for 63-80-100-125A
• SD3 three poles for 125-160-200 A

ADDITIONAL POLES
• Fourth switched pole, solid neutral and earth pole.

OPERATING MECHANISM
• Black (standard execution) or emergency direct handle padlockable in 0 position.
• Handle with and without door interlock handle, black or emergency handle padlockable with up to three padlocks in 0 position.
• IP 65 degree of protection.
• By toggle padlockable in 0 position (switch SD2).
• Wide range of accessories.

CONFORMITY TO STANDARDS
• IEC 60947/1-3
• CEI EN 60947/1-3
• UL 508
• TÜV

CERTIFICATES AND APPROVALS
