The interrupting capacity hits 75.6 kA at 240 V and 52.5 kA at 415 V, so it handles high-fault utility feeds or transformer secondaries without cascading upstream. At 690 V it still clears 10.5 kA, enough for most 690 V motor control centers. The 160 A rating holds flat from 40 °C to 50 °C; above that it derates to 144 A at 70 °C — a useful curve for a warm enclosure with other breakers sharing the space. This is a line-protection version — no ground-fault module, no phase-failure detection, no communication. Mechanical endurance is rated at 15,000 operations — typical for a 160 A frame in a distribution board where it cycles a few times a year, not a daily-switched motor starter. The DIN-rail footprint is 76.2 mm wide by 130 mm tall by 70 mm deep, so it occupies three 25 mm module spaces on a standard 35 mm DIN rail. Panel builders: the depth is shallow enough to clear a 100 mm backplate-to-door clearance. ## Sourcing and lifecycle — current production, quoted to order The 3VA series is Siemens' standard MCCB platform, so documentation (IEC 60947-2, UL 489, CSA C22.2 No. 5) is available from Siemens Support. ## Panel fit and integration — footprint and auxiliaries The two HQ auxiliary switches are pre-installed and wired to the breaker's internal terminal block; they switch at 6 A / 250 V AC for PLC inputs or pilot lights. If the panel was originally specified around a 3VA1010-2ED32-0JA0 (100 A frame), this 160 A unit is physically larger (76.2 mm vs 55 mm wide) and will not drop in without rail space and busbar rework — the rating jump also changes the cable and busbar sizing.","metaTitle":"Siemens 3VA1116-3EF32-0DC0 MCCB, 160 A, 3-Pole, TM240","metaDescription":"Siemens SENTRON 3VA1116-3EF32-0DC0 molded case circuit breaker, 160 A rated, 3-pole, TM240 release, 75.6 kA at 240 V.
