1SCA022611R6660 ABB 6-Pole Stainless Steel Enclosed Switch Disconnector

Why Choose the ABB OTR45B6B Enclosed Switch Disconnector?

The ABB OTR45B6B, order code 1SCA022611R6660, is a robust 6-pole enclosed switch disconnector designed for reliable electrical isolation and load switching in industrial installations. Part of the ABB OTR enclosed switch-disconnector series, it combines dependable switching performance with a durable stainless steel enclosure for machinery, power distribution and automation applications.

Designed as a complete enclosed isolation solution, the OTR45B6B features an IP65 AISI 304 stainless steel enclosure and a black pistol-type operating handle with I-O / ON-OFF indication. The enclosure has a hinged, lockable door with cover interlocking, while the interlock can be defeated where authorised access is required for inspection or thermographic work.

The 6-pole configuration enables simultaneous isolation of six conductors, making the OTR45B6B particularly useful for multi-pole industrial circuits. It provides a rated operational current of 63 A for AC-22A duty up to 690 V and 45 A for AC-23A duty at 415 V, with a 22 kW AC-23A motor rating at 415 V.

Reliable Six-Pole Isolation for Industrial Systems

Enclosed switch disconnectors provide a clearly defined means of isolating electrical equipment from its power supply while also providing load-switching capability appropriate to their utilisation category. The ABB OTR45B6B combines a six-pole switch disconnector, operating mechanism and protective stainless steel enclosure into one robust assembly for dependable local electrical isolation.

The six-pole configuration allows six conductors to be switched simultaneously, supporting applications where multiple circuits or conductors must be isolated together. Its IP65 stainless steel enclosure, black pistol handle, interlocked cover and B-flange cable-entry arrangement make the OTR45B6B suitable for demanding indoor and outdoor industrial installations.

Typical Applications

• Industrial machinery isolation and main switching.
• Six-pole and multi-circuit electrical isolation.
• Industrial motor and production equipment isolation.
• Manufacturing and processing machinery.
• Industrial power distribution systems.
• Control and automation installations.
• Local maintenance and electrical isolation points.
• Indoor and outdoor installations requiring an IP65 stainless steel enclosure.
