7GDS288339R0000 ABB 288339 Interlock for LBS

Why Choose the ABB 288339 Interlock for LBS?

The ABB 288339 Interlock for LBS, manufacturer order code 7GDS288339R0000, is a specialised load break switch interlocking component intended for use in compatible industrial electrical switchgear assemblies. Listed within the ABB GT product group, this component is identified as an interlock for load break switches (LBS), supporting the defined mechanical or operational restrictions required by the associated switching equipment.

Load break switches are used in electrical power distribution systems to make and break circuits under their specified load conditions. Interlocking arrangements can form an important part of these installations by controlling permissible operating sequences, coordinating switching mechanisms or preventing certain operations when defined equipment conditions have not been satisfied. The ABB 288339 is intended for applications where this particular interlocking component is specified by the switchgear manufacturer.

As a dedicated ABB load break switch interlocking accessory, the 288339 supports original equipment construction, planned maintenance and manufacturer-approved replacement applications. Its unique ABB order code enables accurate identification, procurement and component matching, helping electrical panel builders and maintenance engineers maintain the intended operating arrangements of compatible industrial switchgear systems.

Key Advantages

• Purpose-specific interlocking component for compatible load break switches.

Reliable Interlocking for Industrial Load Break Switches

Load break switches are used throughout industrial electrical distribution systems to control circuits within the operating limits established by their manufacturer. Depending on the installation, the switching arrangement may include multiple devices, operating mechanisms and access provisions that require coordinated operation.

The ABB 288339 Interlock for LBS is intended to form part of the designated interlocking arrangement within compatible ABB load break switch equipment. When correctly selected and installed, an interlocking component helps enforce the operating restrictions established by the complete switchgear design.

The effectiveness of an interlocking arrangement depends on correct component positioning, mechanical alignment, engagement with the associated operating mechanism and the condition of related parts. Incorrect installation, adjustment or replacement can compromise the intended operating sequence or interfere with normal switching operation.

The ABB 288339 product designation does not independently establish whether the interlock is mechanical, electrical, key-operated or associated with a particular operating sequence. These characteristics must be confirmed from the applicable ABB technical documentation. The interlock also does not independently determine the rated voltage, current, isolation capability or short-circuit performance of the load break switch.

For dependable operation, the ABB 288339 should only be installed in equipment configurations specifying this component. Installation and servicing should be performed by suitably qualified personnel, with the equipment safely isolated and the complete interlocking arrangement functionally verified before returning the switchgear to service.
