Terminals accept solid or stranded conductors from 0.75 to 35 mm² (AWG 18–4 range), with a tightening torque of 2.5–3.5 N·m (22–31 lbf·in). The combined terminal design (top and bottom) allows looping or daisy-chaining without extra accessories. Polarity must be observed when wiring the supply — this is a unidirectional DC breaker, not a bidirectional type. Halogen-free and silicon-free construction reduces toxic smoke in a fire scenario — relevant for railway and enclosed spaces. The sealable feature lets you lock the toggle position to prevent unauthorized switching, common in safety-critical or remote installations.

Frequently asked questions
Will 5SY5110-6CC11 drop into a panel specified for 5SY3132-6 without rewiring?
The 5SY5110-6CC11 and the 5SY3132-6 share the same 18 mm width, 90 mm height, 76 mm depth, and quick-assembly DIN-rail mounting. Both accept 0.75–35 mm² conductors. The key difference is voltage: the 5SY5110-6CC11 is a DC-rated breaker (220 V DC, 10 kA), while the 5SY3132-6 is an AC-rated breaker (400 V AC, 32 A, 6 kA per IEC 60947-2). Physically they interchange, but the circuit voltage and protection curve must match — do not substitute a DC breaker for an AC application or vice versa.
How do I get current pricing and availability for 5SY5110-6CC11?
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.
What compliance documentation does this brand provide for 5SY5110-6CC11?
The 5SY5110-6CC11 is a Siemens SENTRON miniature circuit breaker designed for railway applications. It carries a DC breaking capacity rating per IEC 60947-2 (10 kA at 220 V DC,) and is rated for overvoltage category III. The product is halogen-free and silicon-free. For RoHS, REACH, UL, or other specific declarations, refer to the manufacturer's documentation — the evidence does not list those certifications directly.
