The breaker carries a maximum breaking capacity of 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V, so it handles high-fault-current scenarios typical of main distribution panels. At 690 V the Icu falls to 3 kA, so if your panel runs at 690 V, this breaker is only suitable for low-fault branches, not the main. For a site electrical engineer planning selective coordination, the 100 A continuous rating and the 150 A minimum breaking capacity give headroom for downstream breakers rated up to that level. That simplifies panel layout — you don't need to oversize the breaker or add forced cooling for a warm enclosure. ## Ground-fault monitoring and communication This MCCB includes ground-fault monitoring using summation current formation on the L + N conductors — it detects leakage by comparing the vector sum of phase and neutral currents. The communication function (listed as present) allows the breaker to report status and trip events to a controller or BMS, which is useful for remote monitoring in a multi-vendor system. Power loss is rated at a maximum of 7.7 W. Dimensions are 86 mm deep, 140 mm wide, and 181 mm high (3.39 x 5.51 x 7.13 inches). The 4-pole width of 140 mm is standard for a 100 A frame — it will drop into a panel cutout sized for a SENTRON 3VA molded case breaker without rewiring, as long as the bus bars and lug spacing match the 4-pole footprint. No undervoltage release or voltage trip is fitted on this variant. No official successor has been announced, so this remains the standard BOM line for a 100 A 4-pole SENTRON MCCB with communication and ground-fault monitoring.","metaTitle":"Siemens 3VA2010-7KQ46-0AA0 SENTRON MCCB, 100 A, 4-Pole, 330","metaDescription":"Siemens SENTRON 3VA2010-7KQ46-0AA0 molded case circuit breaker, 100 A continuous, 4-pole, 330 kA breaking at 240 V.
