Frequently asked questions
What is the breaking capacity of the 5SY5116-6KK11?
10 kA per EN 60898 at AC, and 15 kA per IEC 60947-2 at DC. These are the maximum fault currents the breaker can safely interrupt under the respective standards.
Where can I buy the 5SY5116-6KK11?
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
Will the 5SY5116-6KK11 drop into a panel specified around a 5SY3132-6 without rewiring?
Both are 1-pole SENTRON MCBs on a standard DIN rail, but the 5SY3132-6 is a C-curve variant. The physical footprint (1 MW, 18 mm width) and terminal arrangement are identical, so mechanical fit is the same. The difference is the tripping characteristic — B curve vs C curve — which affects coordination with downstream loads. No rewiring is needed for the breaker itself, but verify the curve matches the circuit's inrush requirements.
