The 3-pole design switches all three phases together, no neutral switching — common for three-phase motor feeds or heater banks. The IP20 rating means it's touch-proof only when wired; mount it inside a sealed enclosure if the panel sees washdown or outdoor spray.

Frequently asked questions
Where can I buy 5SY4304-7CC11 and how do I get a price?
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.
Will 5SY4304-7CC11 drop into a panel specified around 5SY4304-7CV without rewiring?
The 5SY4304-7CC11 shares the same 3-pole, C-curve, 10 kA, 400 V AC rating as the 5SY4304-7CV variant and the same 54 mm width and 76 mm depth. The difference is the '7CC11' suffix indicates a specific ordering code for railway application designation and combined terminals; mechanically it fits the same DIN-rail footprint and wiring pattern, so a direct swap without rewiring is expected.
