SENTRON 3VA2116-5HN32-0KA0 — 160 A MCCB with ETU350 and Shunt Trip
The interrupting ratings climb to 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V — so this breaker handles high-fault utility feeds or transformer secondaries where the available fault current is substantial. The thermal derating curve is flat from 40 °C through 50 °C — still 160 A — then drops to 154 A at 55 °C, 148 A at 60 °C, 142 A at 65 °C, and 136 A at 70 °C. The supplied basic switch is 3VA2116-5HN32-0AA0.
Footprint is 105 mm wide by 181 mm tall by 86 mm deep — standard SENTRON 3VA2 frame size for 160 A. Bolts directly to a backplate or mounts on a DIN rail adapter (not included). The 3-pole block leaves room for side-mounted accessories; the shunt trip occupies the auxiliary release slot, so no room for a second release without a different config. Latching endurance is rated 20,000 cycles, which is typical for a distribution MCCB — not a motor-switching duty cycle, but fine for infrequent manual switching or remote shunt-trip operation.
