That flat thermal curve is unusual for an MCCB this size; most competitors start rolling back above 50 °C. The interrupting ratings climb to 440 kA at 240 V, 330 kA at 415 V, and still 53 kA at 690 V, which puts it in the high-fault-current class for large transformer secondaries or bus-tie positions. ## Selectivity and coordination headroom With 440 kA at 240 V and 330 kA at 415 V, this breaker sits above typical 100 A frame ratings. That headroom matters when you're coordinating downstream branch breakers — you want the upstream device to hold in under fault until the downstream clears. The ETU560's adjustable short-time delay (tr min 0.5 s, tr max 25 s) gives you the time-band to achieve full selectivity with downstream 18 kA or 25 kA MCCBs. Same genuine part, different passport — the 3VA platform is the same hardware whether it shipped from a European or Asian Siemens factory.","metaTitle":"Siemens 3VA2010-8JQ42-0AA0 SENTRON MCCB, 100 A, 4-Pole, 440","metaDescription":"Siemens 3VA2010-8JQ42-0AA0 SENTRON molded case circuit breaker, 100 A rated continuous current, 4-pole, ETU560 release, 440 kA at 240 V.
