01 Identify the item
Existing part number or drawing; component or assembly; sample and batch quantities.
APPLICATION SELECTION
Component Selection for Switchgear OEMs
Building switchgear or replacing a component? Start with the part you need: conductive connections, insulation parts or a switching assembly. Then compare the drawing and the required supply scope.
1. Choose what you need to source
Open a product or category to review its drawings and listed specifications. These are selection starting points, not a complete system configuration.
Conductive connections
For contact replacement or a new connection: compare electrical contacts, tulip contacts, contact arms and conductive rods by mating dimensions and material requirements.
View products & drawings
Insulation parts & embedded poles
For insulating supports and primary-circuit interfaces: compare pole, bushing and support drawings with your cabinet layout.

Switching devices & assemblies
For an assembled switching unit: identify the operating function, mechanism and accessories to be included in the quotation.

A component quotation is separate from a complete-panel quotation. List what must be included, such as mechanisms, controls, wiring and inspection documents.
02 Check electrical duty
System voltage, continuous current and the switching or connection duty required.
03 Match the interfaces
Mating dimensions, mounting holes, drawing revision and any mechanism or control interfaces.
3. Tell us about your project
Start with the information you have; you do not need to complete every technical detail to inquire. Send drawing files to the email address below.

Selection questions
Can existing contacts be used with a new bushing?
Check connection dimensions, contact construction, insulation space and conductor configuration. Being part of the same panel project does not establish interface compatibility.
Is panel information useful for component-only procurement?
Relevant circuit diagrams or local layouts help define interfaces and service conditions. Identify the components supplied by other parties.
