The Siemens SENTRON 3VA2216-5HL32-0AG0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 160 A at 40 °C and derating to 136 A at 70 °C. Its interrupting rating hits 187 kA at 240 V AC and still holds 121 kA at 415/440 V, which puts it squarely in high-fault-duty distribution — think main breaker in a 400 V industrial panel or a large motor control center feeder where upstream transformer capacity is substantial. That means you can coordinate selectivity downstream without swapping the breaker body — a real advantage when the panel feeds multiple sub-feeders and you need the main to hold during a branch fault. Auxiliary contact version is 1 auxiliary switch + 1 trip alarm switch HP, so the panel PLC or BAS gets both a status signal and a separate alarm on trip — no need to add an external relay block for remote indication.
It mounts directly to a DIN rail or panel-mount adapter in the enclosure.
Interrupting capability across voltages
The interrupting ratings step down cleanly: 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 5.1 kA at 690 V. For standard 400 V distribution, the 121 kA headroom covers most transformer sizes up to 2 MVA.
