At 415 V it still manages 121 kA, and at 500 V it's 75.6 kA. The 690 V rating drops to 3 kA, which tells you this breaker is sized for 240–500 V systems, not 690 V feeders. ## Ground-fault and communication features This variant includes ground-fault monitoring via summation current formation on the L + N conductor — it watches for leakage between phase and neutral, not just phase-to-ground. It also has a communication function, so it can talk to a higher-level system for status or trip indication. ## Panel fit The 4-pole width (140 mm) is the same as other 3VA 4-pole frames, so it swaps into existing SENTRON cutouts without re-drilling.","metaTitle":"Siemens 3VA2010-5KQ46-0AA0 SENTRON MCCB, 100 A, 4-Pole, 187","metaDescription":"Siemens 3VA2010-5KQ46-0AA0 SENTRON molded case circuit breaker, 100 A continuous, 4-pole, 187 kA at 240 V.
