Product details

Mounting and integration

Occupies 1 modular width unit (18 mm) on a DIN rail, with a quick-assembly fastening system and any mounting position. Installation depth is 70 mm; overall depth is 76 mm. The compact footprint fits standard 18 mm-spaced enclosures. Combined terminals at top and bottom simplify daisy-chaining busbars or looping through to downstream devices. Polarity of the power supply must be observed — this is a polarized DC breaker. IP20 with connected conductors — suitable for enclosed panel mounting, not for wet or washdown zones.

Frequently asked questions

What is the closest alternative to 5SY5106-7CC12 in the SENTRON family?

The standard SENTRON 5SY4 series offers a similar 1-pole C6 DC MCB but without the railway-specific vibration rating, halogen-free construction, or the extended -40 °C to +75 °C temperature range. For non-rail applications the 5SY4 is a cost-effective substitute; for rail-certified duty the 5SY5 is the correct choice.

What compliance documentation does Siemens provide for 5SY5106-7CC12?

Siemens provides a declaration of conformity for the SENTRON 5SY5 series covering IEC/EN 60898-1 and IEC/EN 60947-2. The halogen-free and silicon-free declarations are part of the standard product documentation. RoHS and REACH compliance is standard for current-production SENTRON parts.

Where can I buy 5SY5106-7CC12 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent industrial-automation distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm delivery commitment.
