❓ Frequently Asked Questions
Q: What does the 36 kA breaking capacity on the LV426315 mean in practice?
A: Breaking capacity (36 kA) is the maximum prospective short-circuit current the LV426315 can safely interrupt without damage. Before installing, verify that the prospective fault level at the installation point does not exceed 36 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: After a short-circuit trip on the LV426315, can it be reset and reused immediately?
A: After a short-circuit trip, do not immediately reset the LV426315. 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 36 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.
