At 63 A this breaker handles a 63 A continuous resistive load at 35 °C; derate to 57.14 A at 45 °C and 50.65 A at 60 °C (–), so plan your thermal budget around the actual enclosure ambient, not the headline number. The 15 kA rating under IEC 60947-2 gives headroom for industrial panels with higher available fault current — a common spec for distribution boards in mechanical engineering and industry.
Two modular-width units (36 mm wide) snap onto DIN rail via quick assembly system in any mounting position. Combined terminal top and bottom accept conductors on both ends. IP20 with conductors connected.
Lifecycle stage is 'current'.
