Breaking capacity is voltage-dependent: 242 kA at 240 V, 187 kA at 415 V, 85 kA at 440 V, 55 kA at 500 V, and 9 kA at 690 V. The N-conductor protection is adjustable from OFF through 20 % to 130 %, giving flexibility for systems where the neutral needs different protection than the phases. The ETU550 trip unit supports communication functions, which means it can integrate into a monitoring or selective-coordination scheme via the SENTRON communication platform — useful for a panel that needs remote trip indication or power-quality data without a separate metering module. Dimensions are 248 mm high, 184 mm wide, and 110 mm deep. Maximum power loss is 63.3 W — not negligible in a densely packed panel. If you're stacking multiple breakers side-by-side, factor that heat into the enclosure's thermal rise calculation, especially above 50 °C ambient where the breaker itself starts to derate. For applications requiring frequent on-load switching (like motor feeders cycled multiple times per shift), consider a contactor upstream instead.","metaTitle":"Siemens 3VA2440-6JP42-0AA0 SENTRON MCCB, 400A, 4-Pole, ETU55","metaDescription":"Siemens SENTRON 3VA2440-6JP42-0AA0 molded case circuit breaker, 400 A rated continuous current, 4-pole, ETU550 electronic trip unit.
