Line protection MCCB with 160 A continuous rating
The Siemens SENTRON 3VA2116-5HN32-0AD0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed for elevated panel temperatures up to that ceiling. Breaking capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — which means this breaker handles high fault currents on the secondary side of a typical 480 V distribution transformer without cascading upstream.
