The integrated auxiliary switch 1NO+1NC gives a remote status contact without eating an extra slot — useful for PLC feedback or alarm annunciation on a tight rail. ## Breaking capacity — two numbers, one decision This breaker carries dual breaking-capacity ratings: 10 kA per IEC/EN 60898-1 and 35 kA per IEC 60947-2. The 10 kA figure governs residential and light-commercial distribution boards tested to the MCB standard. The 35 kA figure applies when the breaker is installed under the industrial standard — typical in a factory sub-distribution board with a higher fault-current capability upstream. For a panel builder, the 35 kA IEC 60947-2 rating is the one that clears the SCCR requirement on most machine-tool and process-line specs. The UL/CSA rating sits at 5 kA for North American installations under UL 1077. ## Panel integration — what fits where The 1 MW width (27 mm) leaves room for a full 24-way distribution board in a standard 600 mm enclosure. The 5SY4106-7XX02 is halogen-free and silicon-free. It carries IEC/EN 60898-1 and IEC 60947-2 certification. For RoHS, REACH, and UL documentation, the standard SENTRON declaration pack applies — available on request with the RFQ.","metaTitle":"Siemens 5SY4106-7XX02 SENTRON MCB, C-Curve 1P, 10kA IEC","metaDescription":"Siemens 5SY4106-7XX02 SENTRON miniature circuit breaker, 1-pole C-curve, 10 kA per IEC/EN 60898-1, 35 kA per IEC 60947-2.

The 5SY4106-7XX02 carries an integrated auxiliary switch 1NO+1NC, which the 5SY4101-7CV does not — so if the original callout was a bare MCB without aux, the auxiliary contacts are extra wiring, not a mechanical fit issue.
