On a DIN-rail panel it occupies one modular width (27 mm,), 76 mm deep, and mounts in any position. 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.
