Ground-fault monitoring uses summation current formation on L+N conductors, and the N-conductor protection is adjustable from OFF to 40%–160% of the phase rating, which is critical for panels with shared neutrals or harmonic-rich loads. ## Thermal Performance and Panel Integration The 86 mm depth (3.39 in), 140 mm width (5.51 in), and 181 mm height (7.13 in) fit standard SENTRON 3VA2 panel cutouts; verify the mounting base if retrofitting an older 3VF or 3VL footprint.","metaTitle":"Siemens 3VA2140-0KQ46-0AA0 SENTRON MCCB, 40 A, 4-Pole, ETU86","metaDescription":"Siemens SENTRON 3VA2140-0KQ46-0AA0 molded case circuit breaker, 40 A continuous, 4-pole, ETU860 electronic trip unit. 440 kA at 415 V.
