SH202-C10: identify the device and isolate the replacement risk
SH202-C10 is the specified two-pole miniature circuit breaker. The complete SH202-C10 designation should remain on the purchase request and maintenance record because a shared family name does not prove interchangeability.
Key technical data for identification
| Technical item | Verified value / selection note |
|---|---|
| Complete designation | SH202-C10 |
| Product family | SH202 |
| Component role | two-pole miniature circuit breaker |
| Poles | 2 |
| Rated current | 10 A |
| Trip characteristic | C curve |
| Order code | 2CDS212001R0104 |
| Final configuration | Confirm exact nameplate, hardware revision and order options before purchase |
For SH202-C10, the table records documented type-level facts and flags items that still require an exact order-code or nameplate check. Use those checks before approving a substitute.
Replacement and acceptance
A replacement for SH202-C10 must preserve the documented interfaces and settings. Confirm correct pole isolation, wiring torque, circuit labeling and trip/test procedure.
After work on SH202-C10, record the installed complete code, observed tests, firmware or setting revision where relevant, and the person approving return to service.
Normal operating duty
SH202-C10 is intended for this system duty: Protect a two-pole branch circuit when the design calls for the specified C-curve rating.
Before selecting SH202-C10, document the actual supply, connected load or signal, operating environment and expected cycle. A similar housing is not evidence of an equal operating envelope.
Fault-isolation route
If the installed SH202-C10 appears faulty, first distinguish a component problem from external wiring, power, field devices or configuration. Check circuit conductors, prospective short-circuit current, selectivity and local standards before substituting another breaker.
Record the symptom and the measurement that supports the diagnosis for SH202-C10. Check the relevant drawings and status indications with the machine in a safe condition; avoid replacing a working device to mask a system fault.

Purchase and handover checklist
Request SH202-C10 by its full designation. Provide quantity, current nameplate image, site wiring diagram and any required certificates. Ask the supplier to identify deviations from SH202-C10 explicitly.
Before returning the system containing SH202-C10 to service, confirm protective devices, terminal assignments, control logic and test records. Retain the final identity of SH202-C10 in the asset history.
