Siemens SENTRON 3VA1096-2ED32-0KF0 — 160 A MCCB with TM220 Release
The interrupting capacity reaches 76 kA at 240 VAC, 53 kA at 415 VAC, and 32 kA at 440 VAC — figures that govern its selectivity in a distribution panel. At 690 VAC the rating drops to 5 kA, so the breaker is best applied on 400 V-class systems where the fault current is known and coordinated.
Above that the breaker derates linearly: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C.
The breaker measures 130 mm in height and 3 inches in width. A mechanical trip indicator and a voltage trigger are built in; the auxiliary contact block (1 aux + 1 alarm HQ) is integrated. The shunt trip (STL) is wired separately; verify the coil voltage matches the control circuit before commissioning.
