The ABB OT630KLAA4BZ (1SCA022342R7030) is a heavy-duty 630 A four-pole steel enclosed switch-disconnector designed for dependable manual load switching and electrical isolation in industrial and commercial low-voltage installations. Part of ABB's established OT enclosed switch-disconnector range, it combines a high-current switching mechanism with a durable steel enclosure and flexible open cable entry arrangements.
Featuring a 630 A frame designation, four-pole switching configuration and IP65 enclosure classification, the OT630KLAA4BZ is suitable for demanding three-phase electrical distribution systems. ABB's catalogue identifies operational switching ratings of 570 A for AC-22A duty up to 690 V AC and 570 A for AC-23A duty up to 415 V AC. These utilisation-category ratings must be considered when selecting the switch for a particular load.
The switch is housed in a steel sheet enclosure measuring 1000 × 400 × 230 mm, providing mechanical protection for the internal switching assembly. It features a black pistol-grip operating handle with I-O and ON-OFF indication, making it suitable for installations requiring a clearly identifiable manual isolation point.
A key feature of the OT630KLAA4BZ is its open top and bottom cable entry arrangement. The enclosure is supplied without cable entry flanges, allowing compatible C-flange or ring-flange accessories to be selected separately. This provides installation flexibility for large power cables and enables the cable entry arrangement to be tailored to the application.
The ABB OT630KLAA4BZ provides a robust manual switching and isolation solution for high-current three-phase electrical installations. Its four-pole mechanism allows four conductors to be disconnected together, making it suitable for appropriately designed three-phase and neutral distribution systems where four-pole switching is required.
Although the model carries a 630 A frame designation, the operational switching ratings must be considered separately. ABB's enclosed switch catalogue specifies 570 A for AC-22A duty up to 690 V AC and 570 A for AC-23A duty up to 415 V AC. The switch must therefore be selected according to the actual operating voltage, utilisation category and connected load characteristics rather than the frame designation alone.
The black pistol-grip operating handle provides a clear manual means of switching between ON and OFF. Its front-operated arrangement makes the isolation point readily identifiable for authorised personnel. Maintenance procedures must follow the site's electrical safety requirements, including securing the isolation where appropriate and verifying the absence of voltage before work begins.
The steel sheet enclosure provides mechanical protection for the switch-disconnector assembly. ABB lists the enclosure range with an IP65 protection classification, indicating dust-tight construction and resistance to water jets when the enclosure is correctly assembled. However, the OT630KLAA4BZ is supplied with open top and bottom cable entry areas, so the completed installation must incorporate suitable entry plates, flanges, glands and seals to achieve the intended environmental protection.
A distinguishing feature of this model is its open cable entry arrangement. Unlike enclosed switches supplied with blanked or preconfigured cable entries, the OT630KLAA4BZ allows compatible C-flange or ring-flange accessories to be selected according to the required cable sizes and routing. ABB's catalogue also identifies the cable entry components as part of the enclosure fixing arrangement, making correct accessory selection important for both installation and mechanical support.
The four-pole arrangement is useful in systems where the neutral conductor must be switched alongside the three phases. However, the complete installation must comply with the applicable earthing arrangement, neutral switching requirements and electrical regulations. Protective earth conductors must remain correctly bonded and must not be interrupted by the switching mechanism.
The OT630KLAA4BZ is a switch-disconnector rather than an automatic circuit protection device. It does not independently provide overload or short-circuit protection. Suitable upstream circuit breakers, fuses or other protective devices must be incorporated into the installation, with the overall electrical system designed for the prospective fault current and required protection coordination.

The ABB OT630KLAA4BZ is a 630 A frame, four-pole steel enclosed switch-disconnector used for manual load switching and electrical isolation in suitable industrial and commercial power distribution installations.
The model has a 630 A frame designation. ABB's enclosed switch catalogue lists operational switching ratings of 570 A for AC-22A duty up to 690 V AC and 570 A for AC-23A duty up to 415 V AC. The appropriate rating depends on the intended switching duty.
The switch has a four-pole (4P) configuration, allowing four main conductors to be disconnected together. It can be used in suitable three-phase and neutral systems where four-pole switching is required.
The enclosure is classified as IP65. Because this model is supplied with open top and bottom cable entries, suitable cable entry flanges, glands and sealing arrangements must be installed to achieve the intended enclosure protection.
The OT630KLAA4BZ is housed in a steel sheet enclosure designed to provide mechanical protection for the internal switch-disconnector assembly.
The switch is supplied with a black pistol-grip operating handle featuring I-O and ON-OFF indication for clear manual switching and isolation.
Open cable entry means that the enclosure is supplied without fitted cable entry plates or flanges at the top and bottom. Compatible accessories must be selected and installed separately according to the cable routing and enclosure sealing requirements.
No. ABB specifies that the OT630KLAA4BZ is supplied without cable entry flanges. Compatible C-flange or ring-flange accessories must be ordered separately.
Yes. ABB's enclosed switch catalogue identifies C-flange and ring-flange cable entry options for this open-entry enclosure range. The correct accessories must be selected according to the cable dimensions and installation requirements.
The enclosure measures 1000 × 400 × 230 mm (H × W × D). ABB's catalogue lists an approximate unit weight of 31 kg.
ABB's enclosed switch catalogue identifies neutral and protective earth terminal facilities for this four-pole steel enclosed switch-disconnector range. The exact connection arrangement should be checked against the supplied installation documentation.
Both are four-pole steel enclosed switch-disconnectors in the same frame range. The OT630KLAA4BZ is supplied with open top and bottom cable entries, whereas the OT630KLUU4BZ is supplied with blank cable entry arrangements. The correct version depends on the installation and cable entry requirements.
Yes, where the operational ratings and installation configuration are suitable. The switch can provide a manual isolation point for industrial machinery, but the complete installation must comply with the applicable electrical safety and isolation requirements.
No. The OT630KLAA4BZ is a switch-disconnector, not a circuit breaker or fused switch. Suitable overload and short-circuit protective devices must be provided separately.
The ABB order code is OT630KLAA4BZ, and the manufacturer product identification number is 1SCA022342R7030. The product belongs to ABB group 311019-Metal Enclosed (Loadbreak).
