The Siemens SENTRON 3VA2116-5HM32-0AA0 is a 3-pole molded case circuit breaker rated for 160 A continuous current, sized for line protection in distribution panels. Its breaking capacity scales with system voltage: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — so the same frame covers high-fault 240 V services and lower-fault 690 V drives without upsizing. Rated insulation voltage is 800 V, and the thermal rating holds 160 A flat from 40 °C through 70 °C ambient — no derating curve to chase in a warm enclosure. Maximum power loss is 25.5 W, manageable in a standard panel layout.
Mounts in a standard distribution board footprint: 105 mm wide, 181 mm tall, 86 mm deep.
