SK825203-B ABB KZD280 NO Main Contact

Why Choose the ABB KZD280 NO Main Contact?

The ABB KZD280 is a genuine normally open main contact supplied as a replacement service component for compatible ABB industrial controlgear. Identified by ABB order code SK825203-B, it forms part of ABB's 3136 Controlgear Service product group and is intended for maintenance of the main power-switching contact system.

The NO (normally open) configuration means the contact is open in its normal de-energised state and closes when the associated switching mechanism is actuated. Correctly matching the contact type is important when maintaining industrial controlgear, particularly where normally open and normally closed contact arrangements may differ between applications.

As a dedicated ABB replacement component, the KZD280 NO main contact provides a practical solution where an existing main contact requires renewal while the remaining compatible controlgear is still suitable for continued service. Using the exact model and ABB order code helps ensure accurate identification when sourcing replacement components.

Reliable Normally Open Main Contact Replacement

Main contacts form the principal current-carrying switching path within compatible industrial controlgear. During repeated operation, these contacts are subjected to mechanical movement and electrical arcing, which can gradually wear the contact surfaces and eventually create a requirement for replacement as part of normal equipment maintenance.

The ABB KZD280 SK825203-B provides the specified normally open main contact configuration for compatible ABB controlgear. Replacing a worn contact with the correctly identified service component can restore the main switching interface while allowing other serviceable elements of the equipment 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.
