Why Choose the ABB KZD220 NO Main Contacts?

The ABB KZD220 NO is a genuine normally open main contact replacement set for compatible ABB industrial controlgear. Supplied under ABB order code SK825203-A, it forms part of ABB's 3136 Controlgear Service product group and provides replacement main contacts for servicing compatible switching equipment.

The NO (normally open) designation identifies these components as main contacts intended to remain open when the associated switching device is in its normal de-energised state and close when the mechanism is actuated. This makes correct identification of the contact configuration essential when selecting replacement components for existing ABB controlgear.

As a dedicated ABB service component, the KZD220 NO main contacts provide a practical solution for maintenance where the existing main switching contacts require renewal but the remainder of the compatible controlgear remains suitable for continued service. The exact ABB order code SK825203-A should be used when identifying this replacement contact set.

Reliable Normally Open Main Contact Replacement

Main contacts carry and switch the load current handled by compatible industrial controlgear. In a normally open arrangement, the contacts are open in their normal state and close when the associated switching mechanism is actuated. Repeated switching can expose these components to electrical arcing and mechanical wear throughout their operating life.

The ABB KZD220 NO SK825203-A provides the specified normally open main contact configuration for compatible ABB equipment. Replacing worn contacts with the correct service component can restore the main switching interface while allowing other serviceable parts of the controlgear assembly to remain in operation.

Typical Applications

  • Maintenance of compatible ABB industrial controlgear.
  • Replacement of worn normally open main contacts.
  • Industrial motor-control equipment.
  • Motor starters and switching assemblies.
  • Machine control systems.
  • Manufacturing and production equipment.
  • Industrial power-switching applications.
  • Preventive controlgear maintenance and repair.
