ABB Disconnects
ABB Disconnects: Precision-Engineered Circuit Isolation
ABB is one of the world's foremost names in electrical engineering, and nowhere is that expertise more evident than in their Disconnects lineup. ABB operates in the fields of electrification and automation, and their disconnect switches represent the intersection of those two disciplines — providing reliable, safe isolation of electrical circuits across a wide range of voltages and applications.
A Broad Portfolio Built Around Safety
ABB offers a variety of safety switches — general and heavy-duty, rotary disconnects, rotary enclosed, fusible, and non-fusible disconnects, as well as medium voltage indoor switches and disconnectors. This depth of product range means that whether you're working with HVAC equipment, motor control, power distribution, or renewable energy systems, there's an ABB disconnect engineered to fit the application.
Available in both fusible and non-fusible models, these switches deliver exceptional reliability during maintenance or emergency shutdowns, and are ideal for use with air conditioners, water heaters, motors, and power distribution panels.
Key Safety Features That Set ABB Apart
ABB's disconnect switches aren't just functional — they're designed with multiple layers of protection for the installer and end user. ABB's disconnect switch lines feature fingerproof construction at IP 20, with dead-front construction plus terminal shrouds that reduce the risk of touching live parts.
- Padlockable handles: Handles can be padlocked in the OFF position with up to three padlocks, and the switch mechanism can be directly padlocked in the OFF position when the door is open.
- Welded contact protection: Positive opening operation safeguards users in case of welded contacts due to an extreme overcurrent situation — the ABB switch design cannot reach the OFF position unless the contacts are truly open.
- Maintenance-free durability: ABB switch-disconnectors are designed, built, and tested for the best possible performance, and are designed to be virtually maintenance-free across their entire extended lifespan. Durability has been ensured by testing against IEC60947-3, UL508, UL98, and CSA standards.
Applications Across Industries
Whether for indoor or outdoor installations, ABB disconnect switches combine durability, flexibility, and safety, making them a trusted solution across manufacturing, renewable energy, and utility applications. The eOT and eOS series of rotary enclosed switches are suitable for use as motor disconnects, while non-fusible disconnects are a high-performance, compact solution for tight panel spaces. Manually operated switch fuses are available from 20 to 1250 amperes, compatible with all types of fuses including DIN, BS, NFC, CC, JJ, and L types.
For anyone sourcing disconnect switches who demands engineering rigor, compliance pedigree, and field-proven reliability, ABB's Disconnects catalog is a natural starting point. Browse the full selection to find the right switch for your amperage, enclosure, and installation requirements.
