Fuseless Manual Motor Disconnect Switches - 3LD2

The 3LD2 manual motor disconnect switches are used for the reliable electrical isolation by switching of main and auxiliary circuits, switching three-phase motors  and other loads such as air conditioners up to 45 KW. The lockable rotary operating mechanism ensures the optimal use as a maintenance and repair switch up to 125 A.

The 3LD2 is the natural choice, during maintenance and repair work or during extended shutdown, due to its simple screwless modular design with minimum space requirement. Switching devices for front panel mounting in control cabinets and machine tools and switching devices with base mounting and a door coupling rotary mechanism in small switchgear installations rated at 16 A to 125 A can be supplied with either four-hole mounting or center-hole mounting. When installed in a molded plastic case, they are suitable for use in environments subject to dust and hosewater. They afford a high degree of protection against accidental contact and integral lockability, when installed in distribution systems in standard masking frames. All available designs are manually operated disconnect switches as defined by IEC 60947-3/ DIN VDE 0660, Part 107 (EN 60947-3). They satisfy the requirements for electrical isolation and also meet the requirements of the directive for electrical machines EN 60204-1.

The 3LD2 has proven to be indispensible in particular for processing machines employed in the mechanical engineering sector, for conveyor systems and in the food industry.

SwitchLine Non-Fusible Disconnect Switches

ABB SwitchLine includes 16 different amperage sizes from 16A to 2000A. The basic construction provides flexibility, safety, and high performance in an extremely compact size. ABB SwitchLine is a perfect choice for all switching applications from industrial motor control to construction safety switches.

Features

• Versatility
• Broad range: SwitchLine consists of seven sizes from 16A-2000A. All sizes are compact, heavy duty, 600V disconnect switches. Many sizes are available in 2, 3, 4, 6, and 8 pole configurations.
• Compact size: The SwitchLine's compact dimensions allow panel size reduction in new applications or easily retrofits into space-sensitive existing applications.
• International acceptance: UL listed, CSA approved, IEC rated, CE marked and most other international standards.
• Mounting: Door mounting on an enclosure door or sidewall (16A-125A), DIN rail mounting (16A-125A) and base mounting with screws (16A-2000A)
• Incoming power feeds: SwitchLine disconnect switches can be used equally well with either top or bottom incoming power feeds.
• Terminal connections: Ring tongue crimp on lugs, direct bus, and terminal lugs
• Modular construction: Modular switch construction allows the operating mechanism to be placed at either end of the switch or anywhere in-between, 200A-2000A.
• Visible blades
• Track resistance material
• Touch safe
• Positive opening operation
• Welded contact protection
• Door interlock
• Padlockable
