The Siemens 3VA1216-6EF32-0AA0 is a SENTRON 3-pole molded case circuit breaker rated 160 A at 40 °C with a TM240 thermal-magnetic release, designed for line protection in distribution panels. Its interrupting capacity reaches 220 kA at 240 V AC, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V — figures that cover high-fault industrial services without cascading upstream breakers. The TM240 release means the thermal element is calibrated for a 160 A frame, giving a continuous current rating that holds flat from 40 °C to 50 °C, then derates to 142 A at 70 °C. That derating curve matters when the breaker is packed into a warm enclosure alongside other heat sources.
The 3VA1216-6EF32-0AA0 measures 105 mm wide, 158 mm high, and 70 mm deep — a 3-pole footprint that fits standard Siemens 3VA panel cutouts and busbar systems.
