Fuse switch disconnectors
ABB’s OS range includes manual fused load break switches from 20 to 1250 amperes, supporting a wide variety of fuse types: DIN, BS, NFC, CC, JJ, and L types. These load break switches deliver top-class performance in demanding applications. The knife-contact design ensures fast fault clearing and maintains the protection level even after a fault occurs. In addition, they are self-cleaning and maintenance-free.
Thanks to their modular design, mechanisms and shafts can be positioned flexibly to meet installation requirements, saving up to 50% installation time. Lockable fuse covers prevent opening while the switch is in the ON position and fully isolate the fuse links when in the OFF position. Furthermore, tested Type 2 coordination tables for motor protection allow for quick and easy selection of ABB motor protection devices, accelerating your projects
Motor operated switch disconnectors
ABB motor operated switch disconnectors provide remote switching over a broad current range, including products rated from 40 to 4000 A. Visible contact positions, suitable terminal protection and lockable manual handles support operation and isolation. Devices are tested to the relevant IEC 60947 requirements, with materials and configurations selected for the application and installation environment.
Manually operated switch disconnectors
ABB’s high-performance compact solutions ensure reliable power distribution even under harsh conditions. These load break switches require virtually no maintenance throughout their long service life and guarantee durability through testing in accordance with IEC60947-3, UL508, UL98, and CSA standards.
In addition, these solutions save space and allow for easy installation. Thanks to their modular design, 2-, 3-, and 4-pole installations can be configured in various positions, while adjustable shafts, mounting feet, and other features reduce installation time and cost. Horizontal, vertical, and ceiling mounting increase installation flexibility, while plug-in auxiliary contacts and terminal covers simplify assembly.
These solutions are ideal for those who want to manage their power distribution reliably and efficiently
