ABB S204M-C20: field fit and operating duty
ABB S204M-C20 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.
Technical data for model selection
| Technical item | Verified value / selection note |
|---|---|
| Complete designation | S204M-C20 |
| Product family | S204M |
| Component role | four-pole S200M miniature circuit breaker |
| Poles | 4 |
| Rated current | 20 A |
| Trip curve | C |
| Order code | 2CDS274001R0204 |
| Series | S200M |
| Final configuration | Confirm exact nameplate, hardware revision and order options before purchase |
The stated S204M-C20 data identify the selected reference and its engineering boundaries. Confirm the unit label, applicable standard and exact options before ordering or energizing.
What must match
Check S204M-C20 against neutral policy, phase loads, fault rating and four-module space. In procurement, ask for photographs or ABB documentation that show the complete designation and terminal configuration.
If the candidate S204M-C20 differs from the installed device, document the difference and obtain an engineering decision before fitment.
Installation controls
Before working on S204M-C20, apply the approved isolation and permit controls. Capture the existing connections, settings and safety functions as a recoverable baseline.
Install S204M-C20 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 S204M-C20, prove all-pole isolation and terminal identification. Record the measured result, witness and date beside the equipment tag.
Retain the final S204M-C20 designation, revision, settings and test outcome in the maintenance record so later work does not rely on memory.
Design intent
The intended duty of S204M-C20 is to protect a four-pole 20 A distribution branch. Mark the circuit, asset or process tag and preserve the plant drawing that governs this function.
Do not assume a different suffix within S204M provides the same duty as S204M-C20; ratings and accessory arrangements can differ.
Fault-finding baseline
For a future fault involving S204M-C20, 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 S204M-C20 should be checked at the same duty point as the prior installation, with abnormal behavior investigated before return to service.
