For ABB 2CCS800900R0021, confirm any version-dependent value from its ABB source and delivered marking before use.
What is the exact component?
ABB 2CCS800900R0021 is the full purchase identity for this combined auxiliary and trip-signalling contact. Confirm the complete code on the delivered marking and the approved parts drawing.
The shared image for ABB 2CCS800900R0021 illustrates the product family only. It cannot confirm the precise current, contact, key, voltage or terminal configuration.
When does this configuration fit?
Use ABB 2CCS800900R0021 where the designed task is to separate open/closed status from overcurrent trip. Define both the normal state and the protective or off state before selection.
Check ABB 2CCS800900R0021 against S800 mounting and signal circuit assignment. Ratings and mechanical interfaces must match the installed circuit, not just the catalog family name.
What does it connect to?
Trace ABB 2CCS800900R0021 into the rest of the assembly: power path, control supply, host breaker, socket, controller or terminal block as applicable. Record each mating part.
For ABB 2CCS800900R0021, inspect mounting clearance, wiring diagrams and permitted accessories. A visually similar version may connect differently.
What would a mismatch cause?
If ABB 2CCS800900R0021 has the wrong current, coil, curve, residual-current type or contact logic, the equipment may not behave as intended. Review the failure mode before substitution.
Do not treat a related ABB 2CCS800900R0021 family code as automatically interchangeable. Preserve the exact configuration and test evidence.
How is acceptance demonstrated?
Commission ABB 2CCS800900R0021 using the equipment's approved procedure and qualified personnel. Test the commanded operation, return state and any alarm or safety signal.
Specifically for ABB 2CCS800900R0021, prove both contact functions. Keep the measured or observed result with the asset record.
What goes on the purchase record?
Specify ABB 2CCS800900R0021 in full, with its ABB reference, required companions and any approved replacement decision. Review availability and lifecycle status for the order date.
A complete ABB 2CCS800900R0021 record prevents a later maintenance team from selecting a superficially similar variant with a different function.
Record the outcome
Accept ABB 2CCS800900R0021 only when exact identity, intended duty, companion parts and operating checks agree.
File the ABB 2CCS800900R0021 test outcome and manufacturer reference with the as-built documentation.
