The Siemens SENTRON 3VA1216-4EF32-0JH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying 160 A continuously at 40 °C and interrupting up to 121 kA at 240 V. That interrupting capacity drops to 75.6 kA at 415 V and 52.5 kA at 440 V — still well into high-fault territory for distribution panels or feeder circuits.
The 160 A frame is rated for continuous current at 40 °C, 45 °C, and 50 °C without derating — still 156 A at 55 °C, 151 A at 60 °C, 147 A at 65 °C, and 142 A at 70 °C. That thermal curve means the breaker handles full load in a warm enclosure; no need to oversize the frame for a typical 40 °C panel ambient. Interrupting ratings across the voltage range give the buyer a clear fault-current envelope: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V. For a 480 V industrial panel, the 52.5 kA at 440 V rating (conservative for 480 V) covers most high-fault scenarios without needing a current-limiting upstream breaker. That means remote tripping and status feedback are built in — no separate accessory order for those functions.
Dimensions are 105 mm wide by 158 mm high by 70 mm deep — a standard 3-pole MCCB footprint that drops into most Siemens SENTRON distribution panels and third-party enclosures with a 105 mm cutout. The 70 mm depth leaves clearance for rear bus connections and cable bending radius.
