Breaking capacity hits 440 kA at 240 VAC, dropping to 330 kA at 415 V and 52.5 kA at 690 V — so it handles high-fault utility feeds or transformer secondaries where the available short-circuit current is substantial. The 184 mm width and 110 mm depth mean it fits standard SENTRON 3VA panel cutouts; no special adapter plate needed for a retrofit into an existing 3VA lineup. ## Derating and thermal budget Step up to 50 °C and it derates to 593 A; at 60 °C it's 557 A; at 70 °C it's 520 A. That's a roughly 17 % drop across the operating range — plan your enclosure ventilation if the breaker sits near other heat sources. Max power loss is 162 W, which drives the internal temperature rise. The ETU340 trip unit is electronic, so it holds its trip curve tighter than a thermal-magnetic through the derating band. Mounts in a standard SENTRON 3VA panel cutout — 184 mm wide, 248 mm tall, 110 mm deep. The N-conductor protection is adjustable: OFF, 50 %, or 100 % of the phase rating, set via a dial on the front.","metaTitle":"SENTRON 3VA2463-8HK42-0AA0 MCCB, 630 A, 4-Pole, ETU340","metaDescription":"SENTRON 3VA2463-8HK42-0AA0 molded case circuit breaker, 630 A, 4-pole, ETU340 electronic trip unit.
