SENTRON 3VA2116-5HN32-0KA0 — 160 A MCCB with ETU350 and Shunt Trip
The Siemens SENTRON 3VA2116-5HN32-0KA0 is a molded case circuit breaker (MCCB) for line protection, rated 160 A continuous current (Iu) across a 3-pole configuration. It carries an ETU350 electronic trip unit with a shunt trip (STL) release — no undervoltage release, auxiliary contacts, or communication module fitted from the factory. 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. Rated insulation voltage is 800 V, and maximum power loss sits at 25.5 W. 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. Operating temperature range is -25 °C to +70 °C; storage can go -40 °C to +80 °C. No trip indicator on the front face, but the voltage trigger (shunt trip) is present, wired via the integrated auxiliary trip order code 3VA9688-0BL33. The supplied basic switch is 3VA2116-5HN32-0AA0.
Panel Fit and Mounting
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.
