Automate your electrical circuits with high accuracy and consistency using the Theben TBN SUL 181D 240V Analogue Timer Switch.
Engineered by Theben, a global leader in time control technology, this mechanical 24-hour time switch provides automated scheduled switching for lighting systems, industrial machinery, ventilation fans, pump controls, and signage illumination.
Operating on a standard 240V AC supply voltage, the SUL 181D model features a prominent 24-hour analogue dial equipped with easy-to-set switching segments (switching pins).
This mechanical design allows electrical installers and facility managers to configure daily ON and OFF operational cycles with complete visual clarity.
Designed for standard 35mm DIN rail mounting, the timer unit seamlessly integrates into distribution boards, main switchboards, and electrical control panels.
The compact modular enclosure protects internal quartz movement components while saving valuable rail space inside panel enclosures.
Additionally, the unit features a clear front protective cover that guards the timer dial against dust, debris, and accidental setting adjustments.
The switch features a manual override switch on the front faceplate, enabling quick toggling between automatic scheduled operation and continuous ON/OFF states for testing or maintenance routines without disrupting preset dial schedules.
