Description
3LD3 switch disconnectors, IU 25 A 3-pole main switch Rated operating power for AC-23 A at 400V 9.0kW Front mounting Basic switch with central hole mounting 22.5mm Rotary drive black 66x66 mm Main and EMERGENCY-OFF switch SENTRON 3LD3 for safe switching off of loads in many areas, e.g. for three-phase motors, air conditioning and ventilation systems, in control or control cabinets, especially for small machines such as saws, compressors, pumps, concrete mixers, drills, Milling or woodworking machines.
Modular design, quick and easy fitting of auxiliary switches, N-PE terminal or 4. Pin Optimum mains separation from 16 A to 63 A by lockable the rotary drive. Can be used versatile thanks to international approvals. A mechanical size for five electrical sizes.
The 3LD main and emergency-OFF switches are available in a wide range of versions for front mounting, mounting plate, DIN rail or distributor installation, optionally with direct or door coupling rotary drive. With 3LD2, variants for DC applications are also available.
3LD main and emergency-OFF switch - consistent safety for users and systems.
