At 40 °C ambient the continuous rating derates to 3.71 A; at 55 °C to 3.22 A. If your panel runs hot, size the load accordingly. Rated 440 V AC multi-phase and 72 V DC maximum. The DC rating is low — this is primarily an AC breaker; for DC circuits above 72 V you need a different pole configuration or a DC-rated series.
Any mounting position; Sealable for tamper-proofing in metering or critical circuits.
This part is sourced to order against an RFQ through independent distribution. Submit a request for current pricing and availability.
The 5SY7206-7CC is a 6 A version in the same 2-pole C-curve SENTRON family. It shares the same 36 mm width, 76 mm depth, and 30 kA breaking capacity, so it drops into the same panel footprint without rewiring — only the current rating differs.
The part carries IEC 60947-2 certification for breaking capacity. It is halogen-free and silicon-free. The product designation follows EN 61346-2 and IEC 81346-2 function code F. For RoHS/REACH declarations, refer to the manufacturer's compliance documentation available on request.
