Line protection design, meaning it's built for feeder and distribution circuits rather than motor or generator protection. Breaking capacity hits 330 kA at 240 V, 242 kA at 415 V, and still 187 kA at 500 V, so it handles high-fault utility feeds without cascading upstream. At 690 V it drops to 3.7 kA — that's the limit for 690 V line-side faults, so verify the available fault current if you're on a 690 V system. ## Ground-fault and communication This unit includes ground-fault monitoring via summation current formation on L + N conductor, so it detects residual currents without a separate toroid — useful for panels where ground-fault protection is required at the feeder level. Communication function is present, which means it can integrate with higher-level monitoring or trip-alarm systems; the exact protocol isn't listed here, but the presence of that function is a differentiator versus the base 3VA2 models without comms. Dimensions are 181 mm high, 140 mm wide, 86 mm deep — that's a standard SENTRON 3VA2 footprint for a 4-pole frame. If you're swapping into an existing panel that was laid out for a 3VA2163-8HM32-0AA0 (a 160 A frame), the width and depth are identical; the height is the same 181 mm. No rewiring needed for the bus bars or mounting holes — it's a drop-in fit on the same mounting pattern.","metaTitle":"Siemens 3VA2110-7JQ42-0AA0 SENTRON MCCB, 100 A, 4-Pole, 240","metaDescription":"Siemens SENTRON 3VA2110-7JQ42-0AA0 molded case circuit breaker, 100 A rated, 4-pole, line protection.
