Benefit
-
Space Savings: With a minimal width of just 22.5 mm, it drastically reduces the required footprint in the control cabinet (up to 82% compared to conventional starter combinations).
-
Hybrid Switching Technology: Combines the best of both worlds: low-wear semiconductor technology for making and breaking, and energy-efficient relay technology for continuous operation, leading to significantly longer service life and reduced heat losses.
-
Integrated Overload Protection: Comes standard with an adjustable electronic overload relay (0.1 – 0.5 A), eliminating the need for a separate thermal overload relay and simplifying wiring.
-
Simplified Installation: Features reliable screw terminals for secure and straightforward wiring of the main and control circuits.
-
High Functional Density: Combines reversing functionality, direct starting, and motor protection in one compact housing.
-
Fast Diagnostics: Integrated LED status indicators allow for quick and accurate troubleshooting and error diagnosis.
-
Wide Application Range: Ideal for controlling auxiliary drives such as pumps, fans, and hoisting equipment in various industrial machines and conveyor systems.
