The interrupting ratings climb to 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and drop to 3.7 kA at 690 V. That SCCR headroom at the lower voltages makes this breaker a strong choice for high-fault-capacity main or feeder positions in a panel. The 86 mm depth by 105 mm width by 181 mm height footprint fits standard SENTRON 3VA2 panel cutouts. These match the standard 3VA2 molded-case breaker footprint, so a panel already cut for a 3VA2 frame accepts this unit without rework. The 3-pole width of 105 mm means it occupies roughly 4.1 inches of DIN-rail or mounting-plate space.","metaTitle":"Siemens 3VA2140-7MQ36-0JA0 SENTRON MCCB, 40A 3P, 330kA at 24","metaDescription":"Siemens SENTRON 3VA2140-7MQ36-0JA0 molded case circuit breaker, 40 A, 3-pole, 330 kA interrupting at 240 V.
