Ratings and thermal derating
The 20 A rating holds at 35 °C ambient; above that the breaker derates linearly — 18.78 A at 40 °C, 18.14 A at 45 °C, 17.48 A at 50 °C, and 16.8 A at 55 °C. The DC breaking capacity is 15 kA at 60 V per IEC 60947-2, useful for DC auxiliary circuits or battery-backed controls.
Fastens via the quick assembly system, mounts in any position.
Rated for mechanical engineering and industry use. Halogen-free and silicon-free construction. The breaker carries IEC / EN 60898-1 and IEC / EN 60947-2 / UL1077 approvals, which means it is accepted across European and North American panels where UL 1077 supplementary protection is recognized. Sealable with a lockable cover to prevent tampering on critical circuits.
