FAQs
Installation involves base mounting with screw terminals, observing the tightening torque of 15 to 22 N·m. Ensure the four-pole assembly is wired to maintain synchronized isolation, and verify the door interlock and padlock provisions are functional. Always de-energize the panel and follow lockout-tagout procedures before connection.
The switch supports a rated operational current Ie of 200 A across 380–415 V, 500 V, and 690 V. Insulation voltage Ui is 1000 V with a rated impulse withstand voltage Uimp of 12 kV. These ratings enable reliable protection in LVAC distribution and motor control applications while maintaining safe clearance margins.
Yes. With 4P configuration, 200 A current rating, and a robust 1000 V insulation, it is well-suited for MCCs and panel boards requiring coordinated disconnection. The front IP20 protection and lockable features further enhance safe operation within indoor switchgear environments.
The device includes CE Declaration of Conformity, RoHS compliance, and Reach declarations. It also aligns with ETIM and eClass classifications for consistent cataloging. These certifications support regulatory compliance, safer procurement, and streamlined engineering validation.
Low power loss per pole (4 W) reduces heat generation and cooling requirements in panels, contributing to energy efficiency. Padlockable operation and door interlocks minimize maintenance interruptions and risk of accidental energization, delivering extended equipment uptime and lower total cost of ownership.
