High current, four-pole configuration supports uninterrupted power transfer in distribution panels. With 1250 A Ith and a rated operational voltage of 1000 V, this switch handles demanding industrial loads with margin. Safety features include a padlockable 0-position handle, door interlocks in I- and II- positions, and a sturdy mounting design that prevents accidental operation during maintenance. Installation and compatibility are enhanced by base mounting, screw terminals, and a 50 mm terminal width, enabling straightforward wiring and repeatable torque (50–75 N·m) across assemblies. The IP20 front protection and RoHS/CMRT declarations simplify field compliance, while a robust mechanical interface reduces commissioning time in new builds or retrofit projects. This device is well-suited for switchgear, motor control centers, and panel-mounted power distribution where reliability and serviceability matter.

FAQs
The unit uses base mounting with screw terminals for straightforward panel integration. Terminal width is 50 mm, and the recommended tightening torque is 50–75 N·m. Front-operated mechanism allows access from the front for quick wiring checks, while the shaft and handle are designed for secure, repeatable operation in confined spaces.
The switch is rated for 1250 A Ith with a rated operational voltage of 1000 V and a 12 kV impulse withstand. It has a front IP20 protection rating, a 4P configuration, and supports safe transfer between sources in power distribution applications, including railings for load switching under fault conditions.
Yes. It carries CE Declaration of Conformity, RoHS compliance for restricted substances, and CMRT reporting. These certifications support regulatory acceptance across European markets and supply-chain transparency for responsible sourcing and sustainability programs.
The device includes a black handle that is padlockable in the 0-position, plus door interlocks active in I- and II- positions. This prevents accidental or unintended operation during maintenance, aligning with safe-lockout practices and reducing the risk of energizing a de-energized circuit.
Ideal for transfer between dual power sources in switchboards, motor control centers, and primary distribution panels. Its high current rating, front-operated design, and robust mechanical interface make it suitable for critical processes requiring quick, reliable source switching with clear-maintenance access.
