EMC-Compatible Motor Isolation with Robust Steel Enclosure Protection
The ABB OT160EVTRR3TZ is designed for industrial electrical installations where dependable isolation and electromagnetic compatibility are important. Its three-pole switching mechanism simultaneously disconnects the three phase conductors of an appropriately designed electrical circuit. This makes it suitable for machinery isolation, motor installations and industrial electrical equipment where a clearly accessible means of disconnection is required.
Unlike conventional enclosed isolators, the OT160EVTRR3TZ incorporates an EMC-oriented ring-flange cable-entry system. This arrangement supports the use of appropriately selected screened cables and EMC termination accessories to help maintain electrical continuity between cable screens and the metal enclosure. Such provisions are particularly valuable in installations containing variable-speed drives, frequency converters and other equipment that can generate electromagnetic interference. Effective EMC performance depends on the complete installation, including cable selection, screen termination, earthing and accessory compatibility.
The switch has a 160 A AC-23A operational current rating across the specified 380–690 V AC range. ABB's enclosed switch catalogue identifies the OT160EVTRR3TZ with an 80 kW motor-output classification at 415 V AC, while its detailed technical information specifies an 88 kW AC-23A rated operational power at 380–415 V AC. The corresponding technical power ratings are 112 kW at 500 V and 144 kW at 690 V. Installers should select the switch using the relevant manufacturer rating and the actual connected load conditions.
The steel sheet enclosure provides greater mechanical robustness than many lightweight plastic enclosures and offers an IP65 ingress protection rating together with IK09 impact resistance. The grey enclosure incorporates a black pistol-type operating handle and an interlocked cover. The cover interlock helps control access to the internal switching assembly, while an override facility permits authorised access under appropriate safe working procedures.
The OT160EVTRR3TZ is supplied with two normally open and one normally closed auxiliary contacts, enabling supplementary indication or control functions in a properly designed circuit. Protective earth terminals are included, but the product does not include a neutral terminal. As a manual switch disconnector, it does not provide automatic overload or short-circuit interruption; suitable protective devices must be incorporated into the installation. The device should be used with appropriate lockout, isolation and absence-of-voltage verification procedures before maintenance.
