It carries a 16 A rating at 40 °C ambient, with no derating needed up to 55 °C — at 60 °C it still holds 15 A. Breaking capacity is the headline here: 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Power loss runs 10.6 W maximum, which factors into thermal coordination inside a crowded enclosure.
At 130 mm high, 101.6 mm wide, and 70 mm deep, this breaker fits the standard SENTRON 3VA footprint. The 4-pole width is about 4 inches — verify busbar spacing and phase-to-phase clearance before committing the panel layout.
