Description
SENTRON, 3LD switch disconnectors, main switch, 3-pole, IU:25 A, Operating power / with AC-23 A at 400V: 9.5 kW, front-mounted, knob drive, black, 4-hole handling attachment SENTRON 3LD2 main and emergency STOP switch for safe switching off of loads in many areas, e.g. for three-phase motors, air conditioning and ventilation systems, in machine and conveyor engineering machines, in the chemical or food and beverage industries.
Modular design, quick and easy fitting of auxiliary switches, N-PE terminal or 4. Pin Optimum mains separation from 16 A to 250 A by lockable the rotary drive. Protection class up to IP 65 with enclosed housing for outdoor applications. Versatile and worldwide usage thanks to international IEC, UL, CCC and shipbuilding approvals.
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.
