Breaking capacity hits 330 kA at 240 V AC, 242 kA at 415 V and 440 V, and 187 kA at 500 V — figures that put it squarely in high-fault-duty service, typically a transformer secondary or a large bus riser where available fault current runs high. At 690 V the rating drops to 3.8 kA, so this is not a 690 V main breaker; it belongs on a 400–500 V distribution board. The ETU330 is adjustable from the front without removing the cover, which saves time during commissioning if you need to tweak the long-time pickup or delay. ## What the ETU330 release gives you The ETU330 is an electronic trip unit with adjustable long-time delay (tr) settable between 0.5 and 17 seconds. That range lets you achieve selective coordination with downstream breakers — you can hold the main closed through a temporary fault on a branch while the branch breaker clears, then trip if the fault persists. An optional motor drive can be added as a field-fit accessory.","metaTitle":"Siemens 3VA2110-7HM32-0AA0 SENTRON MCCB, 100A, 330kA at 240V","metaDescription":"Siemens SENTRON 3VA2110-7HM32-0AA0 molded case circuit breaker, 3-pole, 100A continuous, ETU330 release.
