The Siemens SENTRON 3VA2216-5MN32-0HH0 is a 3-pole molded case circuit breaker (MCCB) designed specifically for motor protection, carrying a full-load amp rating of 160 A that holds flat across the entire 40 °C to 70 °C ambient range — no derating needed up to that ceiling. Breaking capacity is 121 kA at 415 V and 187 kA at 240 V, with a steep drop to 4.5 kA at 690 V, so the interrupting rating at your system voltage governs the panel SCCR calculation.
Physical integration
Dimensions are 86 mm deep, 105 mm wide, and 181 mm high — a standard SENTRON 3VA frame size that fits the common MCC bucket or panel-mount cutout. Maximum power loss is 19.7 W, so thermal dissipation inside a sealed enclosure needs to be checked against the panel's heat budget.
