It's designed for instantaneous tripping — no intentional delay — so it clears a ground fault as fast as the waveform allows. Mounts on a DIN rail (REG) in any orientation. Installation depth is 70 mm, matching the overall depth.
Rated current holds at 63 A from 40 °C through 55 °C ambient. At 60 °C it's still 63 A. Derating starts at 65 °C (56.96 A) and drops to 48.2 A at 70 °C. At 65 °C you lose about 10 % of the 63 A rating; at 70 °C it's down to 48.2 A — roughly 76 % of nominal. Panel builders should check the internal ambient before assuming full 63 A continuous duty.
Integration notes
DIN-rail snap-on, any mounting position. The N terminal is on the left (product variation 'N left'). Silicon-free construction is a plus for environments where silicone outgassing can contaminate contacts or optics — common in automotive paint shops or semiconductor fabs. The let-through current (I²t) is 110 000 A²·s; peak let-through is 7 100 A. These numbers help with selective coordination studies.
