❓ Frequently Asked Questions

Q: What is the significance of the 16 A rating on the SC221616?

A: The 16 A rating is the device’s maximum continuous current carrying capacity under specified conditions (typically 40°C ambient). For circuit design, use 80% of this value as the design current to allow for derating due to grouping, temperature, and future load growth.

Q: What does the 10 kA breaking capacity on the SC221616 mean in practice?

A: Breaking capacity (10 kA) is the maximum prospective short-circuit current the SC221616 can safely interrupt without damage. Before installing, verify that the prospective fault level at the installation point does not exceed 10 kA — this is checked using a fault level calculation or from the upstream transformer impedance data. Installing a breaker with insufficient breaking capacity is a serious safety violation.

Q: Why is Curve C specified for the SC221616 and what loads is it optimised for?

A: Curve C on the SC221616 trips magnetically at 5–10× rated current, making it ideal for general-purpose circuits including fluorescent lamps, small motors, and mixed loads. Using the wrong curve can cause nuisance tripping (too sensitive) or inadequate protection (not sensitive enough). Always match the curve to the load’s inrush characteristics.

Q: After a short-circuit trip on the SC221616, can it be reset and reused immediately?

A: After a short-circuit trip, do not immediately reset the SC221616. First, identify and clear the fault. Then inspect the device — if there is visible arc damage, melted insulation, or the handle does not reset smoothly, the device must be replaced. The 10 kA rated breaking capacity is not unlimited — it is the maximum fault current the device can interrupt safely for a defined number of operations (typically 1–3 at full Icu rating). After any significant fault, factor replacement into your maintenance budget.
