ABB S202P-K16: field fit and operating duty
ABB S202P-K16 should be specified as a complete device, not inferred from a similar family name. Its protection, control or measurement role must match the actual equipment and installation.

The stated S202P-K16 data identify the selected reference and its engineering boundaries. Confirm the unit label, applicable standard and exact options before ordering or energizing.
Design intent
The intended duty of S202P-K16 is to protect an inductive or inrush-prone two-pole load. Mark the circuit, asset or process tag and preserve the plant drawing that governs this function.
Do not assume a different suffix within S202P provides the same duty as S202P-K16; ratings and accessory arrangements can differ.
What must match
Check S202P-K16 against inrush, conductor size, fault current, voltage and K-curve coordination. In procurement, ask for photographs or ABB documentation that show the complete designation and terminal configuration.
If the candidate S202P-K16 differs from the installed device, document the difference and obtain an engineering decision before fitment.
Fault-finding baseline
For a future fault involving S202P-K16, keep records of upstream supply, load, trip or output state and connected accessories. This separates a device issue from a wiring or process issue.
A replacement S202P-K16 should be checked at the same duty point as the prior installation, with abnormal behavior investigated before return to service.
Installation controls
Before working on S202P-K16, apply the approved isolation and permit controls. Capture the existing connections, settings and safety functions as a recoverable baseline.
Install S202P-K16 with the correct conductor, panel spacing and environmental protection. Follow the ABB instructions for the specific construction rather than using a generic wiring assumption.
Handover evidence
For S202P-K16, check trip selectivity and switching of both poles. Record the measured result, witness and date beside the equipment tag.
Retain the final S202P-K16 designation, revision, settings and test outcome in the maintenance record so later work does not rely on memory.

Enquiry checklist
Send the exact ABB S202P-K16 designation with circuit or plant tag, required rating, accessories and approval. Confirm current lifecycle and delivery scope.
On receipt of S202P-K16, compare label, package contents and documentation to the approved request. Hold any discrepancy for review before fitting.
