The Siemens SENTRON 3VA2116-6HL32-0KH0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current at 40 °C, with an adjustable thermal-magnetic trip range from 240 A up to 1 600 A — so you size the trip to the load, not the other way around. Breaking capacity hits 242 kA at 240 V, 187 kA at 415 V, and still 121 kA at 500 V, meaning it clears high-fault currents on industrial distribution without cascading upstream.
The 3-pole footprint matches the 3VA2 family; if you are swapping a 3VA2116-5HL32-0AK0, check the busbar pitch and lug kit — the frame size is the same, so the mechanical drop-in is straightforward, but the trip curve and accessory wiring differ.
The adjustable trip range (240–1 600 A) covers motor feeders, transformer secondaries, and main distribution. Maximum power loss is 25.5 W, so panel ventilation is not a concern for this single unit.
