The ABB OTL45B3M (1SCA022562R4790) is a durable 3-pole enclosed switch disconnector designed to provide safe electrical isolation for industrial machinery, commercial installations and low voltage power distribution systems. As part of the reliable ABB OTL enclosed switch disconnector range, it delivers dependable manual isolation while helping protect maintenance personnel and electrical equipment.
Housed within a rugged powder-coated steel enclosure, the OTL45B3M offers an IP65 protection rating, making it suitable for demanding indoor and outdoor environments. The enclosure features a lockable hinged door with an interlocked mechanism that prevents access while the switch is in the ON position, improving operational safety during servicing and maintenance.
Rated for 63 A AC-21A and 45 A AC-23A at 400-415 V AC with a 22 kW motor switching capacity, the OTL45B3M is ideal for isolating motors, pumps, HVAC equipment and industrial electrical circuits. Its compact enclosure and reliable switching mechanism make it an excellent choice for panel builders, OEMs and electrical contractors.
Enclosed switch disconnectors provide a safe method of manually isolating electrical circuits before maintenance or servicing is carried out. By disconnecting the incoming power supply, they help reduce the risk of accidental energisation and improve workplace safety.
The ABB OTL45B3M combines a high-quality switch mechanism with a weather-resistant enclosure, making it suitable for manufacturing facilities, commercial buildings, utilities and OEM equipment where dependable electrical isolation is essential.
