ABB OT160EVUUR3TZ 160A 3-Pole IP65 UV-Resistant EMC Steel Enclosed Switch-Disconnector
The ABB OT160EVUUR3TZ is a robust 160 A three-pole steel enclosed switch-disconnector designed for reliable electrical isolation in industrial and commercial low-voltage installations. Featuring a galvanised steel enclosure, UV-resistant construction, EMC-compatible design and IP65 ingress protection, this industrial isolator provides a durable switching solution for demanding operating environments.
Identified by ABB manufacturer reference 1SCA147982R1001, the OT160EVUUR3TZ belongs to ABB's Metal Enclosed (Loadbreak) product group. Its three-pole switching mechanism provides simultaneous disconnection of three phase conductors, making it suitable for appropriately rated motors, machinery, electrical distribution circuits and industrial equipment.
The switch features a padlockable operating handle to support controlled maintenance isolation and help prevent unintended operation. Its IP65-rated galvanised steel enclosure provides dust-tight protection and resistance to water jets when correctly installed, while the UV-resistant construction supports applications exposed to sunlight and challenging environmental conditions.
The EMC-oriented enclosure design makes the OT160EVUUR3TZ particularly relevant to installations where electromagnetic compatibility is an important consideration, including industrial automation, variable speed drive systems and electrically noisy industrial environments. Effective EMC performance depends on the complete installation, including cable glands, screening, bonding and earthing arrangements.

Reliable 160A Three-Phase Electrical Isolation
The ABB OT160EVUUR3TZ provides a dedicated switching and isolation point for industrial electrical equipment. Its three-pole configuration allows the three phase conductors of a compatible circuit to be disconnected together, supporting maintenance and operational control.
With a specified 160 A current rating, the switch is intended for appropriately designed low-voltage distribution and machinery applications. Electrical designers must consider the operating voltage, utilisation category, connected load characteristics and prospective short-circuit current when selecting the complete installation.
The switch-disconnector function allows manual circuit isolation and suitable load switching within the manufacturer's applicable ratings. Unlike an automatic circuit breaker, the device is not intended to provide independent overload or short-circuit protection.
The padlockable handle supports maintenance isolation procedures by allowing authorised personnel to secure the operating mechanism against unintended operation. Suitable lockout procedures, verification of isolation and compliance with site safety requirements remain essential.
As a three-pole device, the OT160EVUUR3TZ is intended to switch three conductors. Any neutral conductor and protective earth arrangement must be addressed separately according to the electrical system design and applicable installation standards.
EMC-Compatible Galvanised Steel Enclosure
A distinguishing feature of the ABB OT160EVUUR3TZ is its combination of galvanised steel construction and EMC-oriented enclosure design. This makes it relevant to industrial installations where electrical interference and electromagnetic compatibility must be considered as part of the system design.
Industrial installations incorporating variable frequency drives, power electronics, motor control systems and automation equipment may require appropriate electromagnetic screening and bonding. A conductive metal enclosure can form part of an EMC installation strategy when correctly integrated with suitable glands, screened cables and earthing arrangements.
The EMC designation should not be interpreted as a guarantee of electromagnetic compatibility for the entire installation. Actual performance depends on equipment selection, cable routing, electrical bonding, enclosure continuity and installation practices.
The galvanised steel enclosure also provides mechanical protection for the switching components. Its robust construction makes it suitable for industrial environments where an enclosed isolator must withstand normal operating and maintenance demands.
IP65 Ingress Protection and UV-Resistant Construction
The OT160EVUUR3TZ has an IP65 ingress protection rating, meaning the enclosure is designed to prevent dust ingress and resist water jets when correctly installed and sealed.
Its UV-resistant construction supports use in environments exposed to sunlight, making it a suitable candidate for appropriately designed outdoor installations as well as industrial indoor applications.
For outdoor installation, the electrical designer should consider ambient temperature, condensation, corrosion exposure, cable-entry sealing and the mounting environment. Suitable cable glands and accessories must preserve the required IP rating and EMC performance.
The combination of 160 A switching capability, three-pole construction, IP65 protection, UV resistance and galvanised steel housing makes this enclosed switch-disconnector a practical choice for demanding industrial electrical installations.
