Why Choose the ABB 288109 Main Contacts?
The ABB 288109 is a dedicated main contacts component intended for use in compatible electrical switching equipment and switchgear assemblies. Identified by ABB order code 7GDS288109R0000, this component belongs to the ABB GT product group and is designed for applications requiring the specified main contact arrangement.
Main contacts are essential components of electrical switching devices, providing the conductive interface through which electrical current flows when the switching mechanism is in its closed position. During an opening operation, the contacts separate as part of the switching process. Correctly specified main contacts are important for maintaining the intended electrical and mechanical performance of compatible switching equipment.
The ABB 288109 Main Contacts are suitable for switchgear servicing, maintenance and replacement applications where ABB component reference 288109 is specified. Their dedicated manufacturer order code enables accurate identification when sourcing replacement contact components for compatible industrial and commercial electrical power distribution equipment.

Reliable Main Contact Performance for Electrical Switching Equipment
Main contacts form part of the principal electrical current path within many switching devices, including circuit breakers and switches. When the switching device closes, its main contacts establish an electrical connection that allows current to flow through the equipment. When the device opens, the contacts separate as part of the mechanism used to interrupt or isolate the electrical circuit, according to the design and rating of the complete switching device.
The ABB 288109 Main Contacts provide a designated contact component for compatible ABB switching equipment. Correct replacement should follow the manufacturer's maintenance instructions, including requirements for contact condition, alignment, operating mechanism adjustment and associated components. Electrical ratings, switching capacity and compatibility must be determined from the complete approved equipment configuration rather than the contact component designation alone.
Typical Applications
- Main contact arrangements in compatible electrical switching devices.
- Electrical switchgear servicing and maintenance.
- Industrial power distribution switching equipment.
- Commercial electrical switchboard assemblies.
- Refurbishment of compatible ABB switching mechanisms.
- Replacement of existing ABB 288109 main contact components.
