ABB S200 Miniature Circuit Breakers

Protection purpose and product range

S200 miniature circuit breakers provide overload and short-circuit protection in residential, commercial and industrial installations. The existing references include different pole configurations and S200/S200 M variants; the complete designation determines the applicable performance and approvals.

Do not assign a single 10 kA rating, current range or certification to every listed breaker. AC and DC duties must be checked separately. ABB documents S200 M UC as a dedicated AC/DC range; that capability must not be assumed for a standard S200 model.

Conditions that determine selection

• Specify supply voltage, AC/DC duty and frequency, circuit load and the required pole/neutral arrangement.
• Select rated current in relation to conductor capacity, load demand, installation temperature and applicable derating.
• Choose the tripping characteristic using load inrush and the required protection/disconnection conditions. B, C, D, K and Z characteristics are not interchangeable selection labels.
• Verify breaking capacity at the actual operating voltage and under the applicable standard; distinguish Icn from industrial Icu/Ics ratings.
• Check terminals, conductor/busbar arrangement, mounting space and exact accessory compatibility using the applicable product documentation.

Standards and application boundaries

ABB documentation distinguishes IEC/EN 60898-1 and IEC/EN 60947-2 duties. The applicable curve, rating and approval must be verified for the full product code. UL/CSA markings or a supplementary-protector approval do not automatically establish UL 489 branch-circuit suitability. Neither an MCB nor its auxiliary contact provides residual-current protection by itself.

Model identification and quotation

The original 2,027 model and Order Code references remain available below. Historical entries are retained without guessing certification, availability or replacement relationships. Send the full model, ABB Order Code, quantity and destination country, plus supply voltage, poles, current, trip characteristic, required breaking duty and standard. For an existing installation, include a nameplate photo and accessory details.
