Front-operated, four-pole design with door mounting enables rapid Actuation and safe isolation directly at the panel face, reducing maintenance time and exposure during disconnection. This design increases worker safety while speeding routine testing and lockout procedures in service panels. The unit is rated for 160 A across 380–415 V, 500 V and 690 V, with a rated impulse withstand of 12 kV and a short-circuit withstand up to 12 kA, delivering reliable performance in distribution boards and machine controls. Screw terminals support Cu 10–70 mm² cables, with a tightening torque of 6 N·m, ensuring secure connections that resist vibration in industrial environments. Front IP20 protection, RoHS compliance, and environmental declarations (CMRT/EPD) provide regulatory confidence for indoor installations and sustainability goals. The 4P configuration, with the fourth pole on the right side and a switched-simultaneous function, supports consistent operation in multi-pole circuits, while the absence of a handle and shaft allows flexible integration with customer-supplied or optional accessories. Durability is built in with 20,000 mechanical cycles and a compact footprint of 150 mm × 130 mm × 75 mm, enabling easier retrofits in existing panels and future upgrades without major enclosure modifications.

FAQs
The device uses a door mounting configuration with screw terminals suitable for Cu cables from 10 to 70 mm². It supports a 4P arrangement with the fourth pole on the right side, and the handle/shaft are not included, allowing integration with customer-supplied accessories and compact enclosure layouts.
The unit handles 160 A across 380–415 V, 500 V, and 690 V, with a rated impulse withstand of 12 kV and a conventional current rating of 160 A. It provides a short-circuit current capability of up to 12 kA and front IP20 protection, suitable for indoor industrial applications.
Yes. With 160 A ratings, 1000 V insulation, 12 kV impulse withstand, and 12 kA short-circuit capability, the device is compatible with 380–415 V systems typical in distribution panels and machine controls, offering reliable isolation and safe maintenance.
The product complies with IEC 60947-3 and UL 98, carries CE declarations, and is supported by DNV GL/CSA references in its documentation. It also aligns with RoHS requirements and provides IP20 protection for indoor installations.
With a mechanical durability rating of 20,000 cycles and straightforward front-access installation, maintenance intervals are shorter and downtime is reduced. The compact 150 x 130 x 75 mm footprint simplifies retrofits and reduces enclosure modification costs, delivering a favorable total cost of ownership in legacy panels.
