The 86 mm depth clears most standard enclosure back-pan depths. The 140 mm width for a 4-pole MCCB is a standard SENTRON frame size, so busbar kits and mounting feet fit without modification. ## Selectivity and coordination With a minimum trip setting of 60 A and a full-scale value of 40 A, this breaker is set up for a 40 A feeder. The ground-fault monitoring uses summation current formation on L + N conductor. ## Communication and auxiliary functions This MCCB includes a communication function, so it can integrate with a monitoring system for remote trip indication or load data. The 2.2 W maximum power loss is low enough that multiple breakers in a panel don't create a thermal problem — useful when you're stacking feeders in a compact enclosure.","metaTitle":"Siemens 3VA2040-6JQ46-0AA0 SENTRON MCCB, 40 A, 4-Pole, 242 k","metaDescription":"Siemens SENTRON 3VA2040-6JQ46-0AA0 molded case circuit breaker, 40 A continuous, 4-pole, 242 kA breaking capacity at 240 V.
