£1,023.25
The ABB OTR100BA3B (1SCA022569R7320) is a heavy-duty 3-pole enclosed switch disconnector designed to provide safe and dependable electrical isolation for industrial machinery, commercial installations and low voltage power distribution systems. As part of the robust ABB OTR enclosed switch disconnector range, it combines reliable switching performance with a corrosion-resistant stainless steel enclosure for demanding environments.
Manufactured with a rigid AISI 304 stainless steel enclosure, the OTR100BA3B offers an IP65 protection rating, making it suitable for both indoor and outdoor applications. The enclosure features a hinged, lockable door with an interlocked cover that prevents access while the switch is energised, enhancing operator safety during maintenance. The interlock can also be temporarily overridden for thermographic inspections.
Rated for 100 A with an 80 A AC-23A utilisation rating and a 37 kW motor switching capacity at 380-415 V AC, the OTR100BA3B is ideal for isolating motors, pumps, compressors, HVAC equipment and industrial power circuits. The enclosure includes integrated neutral and protective earth terminals together with top and bottom cable entry knock-outs for straightforward installation.
Enclosed switch disconnectors provide a safe means of isolating electrical equipment before inspection, servicing or maintenance. By disconnecting incoming power, they help reduce the risk of accidental energisation while protecting personnel and equipment.
The ABB OTR100BA3B has been designed for demanding industrial environments where corrosion resistance and reliable switching performance are essential. Its stainless steel enclosure makes it particularly suitable for food processing, water treatment, marine and chemical industry applications.
