• Rated for 20 A continuous current (AC-21A) at 690 V AC
• Panel mount with screw terminals and black handle
• Front protection degree IP66; terminals IP20
• Meets IEC/EN 60947-3, UL, and CSA standards
• Long service life: 100,000 electrical operations, 1,000,000 mechanical operations

In daily use

Installation is straightforward thanks to the panel-mount design and clearly marked screw terminals. The black handle provides a secure grip for switching between positions, even when wearing gloves. With an operating temperature range of -25°C to +50°C, this switch performs reliably in harsh conditions. The IP66 front protection ensures resistance to dust and powerful water jets, while the IP20 terminal area is suitable for protected environments. The cam code 8243 defines the specific switching sequence, enabling predictable control of connected loads.
