Selection Guide

1

Indoor use

Cast-resin, oil-free design is ideal for indoor commercial and industrial installations.

2

Efficiency

Level 3 efficiency - a solid balance of cost and energy performance.

3

Cooling

Natural air cooling (AN) standard; forced air (AF) available for higher capacity.

- Frequently Asked Questions

What efficiency level does SCB13 meet?

SCB13 meets Level 3 energy efficiency (GB 20052), reducing no-load losses versus conventional dry-type transformers.

Can SCB13 be installed indoors?

Yes, cast-resin construction is fire-safe and oil-free, ideal for indoor commercial and industrial installations.

What is the typical service life?

Over 30 years with Class F insulation and adequate ventilation.

Derived Ratings (calculated from the configuration)

The values below are computed from what you selected above. Anything that cannot be computed yet is shown as an em dash — never as zero.

Iₙ = S / (√3·U) · I_sc = 100·Iₙ / uₖ · S_sc = √3·U·I_sc · I_p = k·Iₖ

Inputs taken from the configuration

Short-circuit current I_sc—
Short-circuit power S_sc—
I_sc is calculated on the transformer impedance basis alone (system impedance neglected) — the same basis used in IEC 60076-5 short-circuit calculations.
System voltage → —

Still required to complete the calculation: rated capacity S, impedance voltage uₖ, short-time or peak withstand current.

Per-model values (P0 / Pk / uₖ declared by the factory, losses, noise, temperature rise, dimensions, weight) are not in the product library: those rows stay at an em dash until the factory parameter sheet is supplied. An em dash means the value is unavailable — it is never rendered as zero.

Derived losses (from the selected efficiency grade + capacity)
Class 2 (SCB13)
No-load loss P0 (kW)—
Load loss Pk (kW)—

Read-only: no price factor, not part of the sum — the loss-grade cost is already carried by the efficiency (subtype) base price, so charging here would double-bill. Values come from the product library type-test data, interpolated between published capacities; grades the library does not cover show an em dash, never zero.
