Its 50 A rating at 30 °C (46.97 A at 40 °C, 46 A at 45 °C, 42.01 A at 55 °C) means the breaker must be derated when installed in a warm enclosure; the 40 °C figure is the one to use for most panel environments. Breaking capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2 at 400 V AC — the higher IEC figure is the one to reference for industrial panel SCCR coordination.
Deployment context
Sealable, halogen-free, silicon-free construction meets modern low-smoke material specs for public-building installs.
