Commissioning engineer's spec recap
At 40 °C it carries a full 50 A continuous; the thermal curve holds flat through 50 °C, then derates to 45 A at 70 °C. Breaking capacity lands at 75.6 kA at 240 V, 52.5 kA at 415 V, and 11.9 kA at 690 V — sufficient for most industrial distribution panels fed from a transformer secondary.
The breaker occupies a 76.2 mm wide by 130 mm tall by 70 mm deep footprint — a standard 3-pole MCCB envelope that fits most DIN-rail or panel-mount backplates. Maximum power dissipation is 17.1 W at full rated load. In a sealed, uncooled enclosure this heat must be factored into the thermal budget — adjacent devices may need derating if airflow is restricted.
This covers most indoor industrial environments and unheated warehouses. The part is not rated for marine or offshore use without additional type-approval documentation — no DNV, ABS, or Lloyd's certificate is listed in the standard spec set.
