The interrupting ratings climb with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. Above that it derates gradually, down to 144 A at 70 °C. Front face carries an IP40 rating — fine inside a clean distribution board or motor control center, but keep it out of washdown zones. The 70 mm depth and 76.2 mm width fit standard SENTRON mounting footprints; it bolts onto the same busbar system as the rest of the 3VA family, so swapping a 125 A unit for this 160 A one doesn't require re-drilling the panel. If you need signaling or undervoltage protection, that has to come from an add-on module, not the breaker body. The latching endurance is rated at 15,000 operations — that's the mechanical life for the switching mechanism, not the electrical endurance under load. For a main feeder breaker that cycles maybe a few hundred times a year, that's decades of service. If you're using it for frequent switching, derate the electrical life per the Siemens manual.","metaTitle":"Siemens 3VA1116-3EF32-0HA0 SENTRON MCCB, 160 A, 3-Pole","metaDescription":"Siemens 3VA1116-3EF32-0HA0 SENTRON molded case circuit breaker, 160 A rated continuous current, 3-pole, line protection, TM240 release, 75.6 kA at 240 V.
