Fuse Switch Disconnectors
ABB's OS range includes manual type fused switch disconnectors from 20 to 1250 Amps and supports a variety of types: DIN, BS, NFC, CC, JJ and L types. These switch-disconnectors offer first-class performance in demanding applications. The blade contact design ensures rapid fault clearance and maintains the level of protection even after the fault has occurred. Additionally, they are self-cleaning and maintenance-free. Thanks to their modular construction, the mechanism and poles can be positioned to suit arbitrary installation requirements. This saves up to 50% in installation time. Locking fuse covers prevent opening when the switch is in the ON position and completely isolate the fuse links when the switch is in the OFF position. Additionally, tested type 2 coordination tables for motor protection allow you to select ABB motor protection devices quickly and easily, speeding up your projects.
Motorized Load Breakers
ABB's motor switch breakers are designed for remote operation over a wide current range from 40 to 4000 Amperes. These devices are equipped with various security features, such as IP20 finger-proof systems. All contacts are clearly visible, making the position indication clear and reliable. It is also equipped with a handle for manual use in emergency situations, and the handles can be locked to ensure safety. ABB's motorized switch breakers have been tested according to the IEC 60947 standard to ensure high performance in applications requiring remote operation. Additionally, it is equipped with highly durable insulation materials, offering reliability even in harsh conditions to help reduce the risk of flash arcs.
Manual Load Breakers
ABB's high-performance compact solutions enable reliable electricity distribution in harsh conditions. These switch-disconnectors require virtually no maintenance throughout their long life and ensure durability through testing based on IEC60947-3, UL508, UL98 and CSA standards. Additionally, these solutions save space and offer easy installation. Thanks to the modular design, 2, 3 and 4 pole installations in different positions are possible, while adjustable shafts, mounting feet and other features reduce installation time and costs. Horizontal, vertical and ceiling mountability increases installation flexibility, while plug-in auxiliary contacts and terminal covers facilitate installation. These solutions are ideal for those who want to manage their electricity distribution reliably and efficiently.
