FAQs
This unit is designed for base mounting with screw terminals (20 mm spacing) and a tightening torque of 15–22 N·m. It fits standard 3P switchgear footprints and connects via screw terminals, enabling straightforward panel integration. Ensure mounting clearance for the 194 mm width, 150 mm height, and 160 mm depth, and verify supply voltage within the 380–415 V range for full performance.
The switch is rated Ith 200 A, Ui 1000 V, and Uimp 12 kV, with Ie values of 200 A across 380–415 V, 500 V, and 690 V categories. These ratings indicate suitability for medium-to-high power applications, including motor feeders and critical loads, while providing adequate insulation and surge withstand for reliable operation in demanding environments.
Ideal for main switchgear, redundant power paths, and motor feeder configurations in manufacturing and process industries. The 3P fast-transition design with a 90° action minimizes transfer time, supporting uptime in critical processes, while the IP20 rating ensures safe operation inside control cabinets.
The product includes CE Declaration of Conformity, RoHS and Reach declarations, and a DNV certificate reference. These certifications support regulatory compliance for global deployments and reduce risk in audits and procurement reviews.
With a rugged mechanical design, base mounting, and screw-terminal connectivity, maintenance is simplified and field servicing is faster. The 200 A rating and reliable Uimp/Ui specs reduce the need for frequent replacements in high-load panels, translating to lower lifecycle costs and improved uptime in critical industries.
