Mounts via the quick-assembly system onto a DIN rail; 36 mm width (2 width units) and 76 mm depth fit standard SENTRON distribution boards. Installation depth of 70 mm leaves clearance behind the panel for wiring. Accepts solid or stranded conductors from 0.75 to 35 mm² at the screw terminals, torqued to 2.5–3.5 N·m (22–31 lbf·in). Combined top and bottom terminals simplify daisy-chaining busbars. Mounting position is unrestricted; IP20 with connected conductors is standard for enclosed panel use. Note the polarity marking on the supply side — DC arc extinction requires correct orientation.

Frequently asked questions
What is the DC breaking capacity of the 5SY5206-6CC11?
The 5SY5206-6CC11 is rated for 10 kA breaking capacity at 440 V DC per IEC 60947-2, and can handle up to 500 V DC maximum.
Will the 5SY5206-6CC11 drop into a panel specified for the 5SY3132-6 without rewiring?
No direct drop-in — the 5SY5206-6CC11 is 36 mm wide (2 width units) versus 18 mm for the single-pole 5SY3132-6, and it requires DC polarity consideration. The 5SY3132-6 is an AC-rated breaker with 72 V DC max, so the 5SY5206-6CC11 serves a different application entirely.
Where can I buy the 5SY5206-6CC11?
This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time.
What compliance documentation does Siemens provide for the 5SY5206-6CC11?
The breaker is designed to IEC 60947-2 and carries the SENTRON brand. It is halogen-free and silicon-free by design. Specific compliance certificates (CE, UKCA, EAC) are standard for the SENTRON series; request documentation with your RFQ.
