Why Choose the ABB OTR125BA3U Enclosed Switch Disconnector?
The ABB OTR125BA3U, order code 1SCA022569R7910, is a robust 125 A 3-pole enclosed switch disconnector designed for reliable isolation and load-breaking duties in industrial electrical installations. Part of the ABB OTR enclosed switch-disconnector range, it combines a high-performance switching mechanism with a durable stainless steel enclosure for dependable operation in demanding environments.
Designed as a complete enclosed switching solution, the OTR125BA3U features an IP65 stainless steel enclosure together with a highly visible red-yellow operating handle. The enclosure incorporates cover interlocking to help prevent access while the switch is in the ON position, while the defeatable interlock function supports authorised inspection and maintenance procedures.
With a rated current of 125 A, three switching poles and a stainless steel enclosure measuring approximately 300 × 200 × 135 mm, the OTR125BA3U is well suited to industrial power distribution, machinery isolation and electrical control installations. This U-version is supplied with blank cable entry areas, allowing installation requirements to determine the appropriate cable-entry arrangement.

Reliable Isolation and Load Switching 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 operating category. The ABB OTR125BA3U combines the switching device, operating mechanism and protective enclosure into a single industrial assembly, simplifying installation where a separate enclosure is unnecessary.
Its stainless steel IP65 enclosure makes the OTR125BA3U particularly suitable for industrial locations where electrical equipment may be exposed to dust, moisture or demanding operating conditions. The red-yellow operating handle provides clear visual identification, while the interlocked enclosure supports safer access during inspection and maintenance.
Typical Applications
- Industrial machinery isolation and main switching.
- Three-phase power distribution systems.
- Motor and production equipment isolation.
- Manufacturing and processing machinery.
- Industrial control and automation installations.
- Pumps, fans and material handling equipment.
- Maintenance and local electrical isolation points.
- Industrial installations requiring an IP65 stainless steel enclosure.
