The Siemens SENTRON 3VA2116-5HN46-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for 160 A continuous current, designed for line protection in distribution panels and motor control centers. It carries a 187 kA interrupting capacity at 240 V, dropping to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — the high short-circuit rating at the lower voltages means it handles fault currents on the secondary side of a 480 V transformer without needing an upstream current-limiting fuse.
The 160 A continuous rating holds flat from 40 °C through 70 °C — no derating curve to calculate for a hot cement plant or steel mill control room. Footprint is 140 mm wide by 181 mm tall by 86 mm deep — the 4-pole body fits standard Siemens SENTRON mounting bases.
