The 330 kA at 240 V is the headline number, but the real-world decision point for most industrial panels is the 242 kA at 415 V — that covers common 400 V class distribution. The 3 kA at 690 V is a residual rating; this breaker is not your primary choice for 690 V switchgear. The 140 mm width is the key dimension for multi-pole grouping in a panel — four poles at that width means 35 mm per pole, which is typical for this frame class. ## Ground-fault and monitoring capability This variant includes ground-fault monitoring via summation current formation on L + N conductors — it senses the vector sum of line and neutral current, so it catches leakage to ground without a separate sensor.","metaTitle":"Siemens 3VA2010-7HM46-0AA0 SENTRON MCCB, 100 A, 4-Pole, 330","metaDescription":"Siemens SENTRON 3VA2010-7HM46-0AA0 molded case circuit breaker, 100 A continuous, 4-pole, interrupting rating 330 kA at 240 V.
