The 4 A rating is at 35 °C ambient; at 40 °C it derates to 3.76 A, at 50 °C to 3.5 A, and at 60 °C to 3.23 A. The 10 kA breaking capacity at 230/400 V AC is adequate for most secondary distribution panels; for higher fault currents you would step to the 15 kA or 25 kA variants in the same 5SY4 family.

The -8CC11 is the railway-grade variant with a wider temperature range (-40 to 75 °C), vibration qualification per IEC 60068-2-6, and halogen-free/silicon-free construction. The -7CV is the standard commercial version. Both share the same 1-pole 18 mm footprint, D-curve, 4 A rating, and 10 kA breaking capacity, so the -8CC11 drops into the same panel position without rewiring.
The depth is 76 mm, with an installation depth of 70 mm. Width is 18 mm (1 modular unit), height is 90 mm.
Yes — same 1-pole 18 mm DIN-rail footprint, same quick-assembly system, same combined terminals top and bottom. No rewiring or panel modification needed.
The breaker is designed per IEC 60898 and IEC 60947-2. It is halogen-free, silicon-free, and sealable. Manufacturer declarations for RoHS, REACH, and UL are available through the standard documentation request process.
