Dimensions: 181 mm height, 140 mm width, 86 mm depth. ## Ground-fault and N-conductor protection The ground-fault monitoring uses summation current formation on L + N — it sees the vector sum, not a separate sensor. The N-conductor protection is adjustable from OFF to 20–160 % of the phase setting, which matters for 4-wire systems where the neutral can carry harmonic content.","metaTitle":"Siemens 3VA2110-0KQ46-0AA0 SENTRON MCCB, 100 A, 440 kA at 41","metaDescription":"Siemens SENTRON 3VA2110-0KQ46-0AA0 molded case circuit breaker, 100 A continuous, 440 kA breaking at 415 V, ETU860 trip unit, 4-pole, active production.
