Solicitud

Industrial sites with abundant non-linear loads (VFD, rectificadores, Unión Postal Universal) and high harmonic content. Compared with standard BLRCS, it has greater harmonic margin and lower risk of bulging and premature failure.

Alternativas & Cross-reference within series

Standard version with same rating: BLRCS200A240B40 (EasyCan, for low harmonic scenarios, menor costo)

Same capacity, higher voltage: BLRCH200A240B44 (440V)

Selección & Notas coincidentes

1. Heavy-duty capacitors are still recommended to use series detuned reactors for harmonic mitigation;
2. Switching device: Schneider VarLogic dedicated capacitor contactor is preferred for inrush suppression;

Engineering reference: For 50Hz systems in China, 28.9A is taken as base rated current;

Max allowable continuous current of capacitor: 1.8×In → approx. 51.9A at 50Hz

Componentes a juego (contactor, cortacircuitos, cable) to be sized at 1.5~1.8×In:

contactor: Schneider LC1DK dedicated capacitor contactor (inrush-limiting type), ≥40A class recommended

Cortacircuitos: curva D, 32A or 40A

Cable: Copper conductor ≥10mm² for short cabinet wiring; 16mm² for long runs or high ambient temperature

Recordatorio importante: After series connection with reactor, voltage across capacitor rises and actual operating current increases. Do not use the base 28.9A directly for sizing; correction according to reactor percentage is mandatory.

Alternativa doméstica: CKSG dry-type series reactor (CKSG-1.4/0.48-7%)

III. Critical Risk Notes for this model

1. BLRCH heavy-duty does NOT mean reactor-free. Capacitors will bulge and fail early under heavy harmonics without reactor; it only has higher tolerance margin than BLRCS.
2. Uniform reactor percentage for all branches within one PFC cabinet. Mezclando 7% y 14% detuned branches in same cubicle is not allowed, risk of internal resonance and harmonic amplification.
3. Switching cycle limit for detuned branches: máx. 7000 operations per year (capac inherent limit).
4. CT for power factor controller: Install CT on grid side before reactor, not after capacitor branch.

Sizing Hard Rules

1. 5.7% (210Hz) reactors are fully discontinued by Schneider, no new specification; legado 5.7% projects migrate to 7%.
2. Uniform reactor percentage inside one PFC panel. Mezclando 7% y 14% branches causes resonance hazard.
3. 14% detuned branches strongly recommend 440V capacitor upgrade; 400V capacitor suffers accelerated ageing under sustained overvoltage.
4. Reactor rated current to be sized on harmonic-amplified operating current, not only fundamental 28.9A.
