The Siemens 3VA2116-5HN32-0HH0 is a SENTRON molded case circuit breaker (MCCB) rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed until you cross 70 °C. That 160 A holds steady at every temperature step in between, which simplifies panel design in warm enclosures or near heat-producing gear.
Breaking Capacity — What the Ratings Actually Mean
This MCCB carries a 187 kA interrupting rating at 240 V, which drops to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and finally 3.7 kA at 690 V.
The width is the critical number for DIN-rail or mounting-plate layout — three of these side by side eat 315 mm of rail space. Height of 181 mm is compact for a 160 A frame, so it clears most standard gland plates.
Auxiliary Hardware Built In
That means you get remote status indication and remote trip capability without ordering separate accessory kits — it's wired and ready. The shunt trip lets a safety PLC or E-stop circuit drop the breaker remotely, which is common in emergency-off chains or interlocked machine cells.
Maximum power loss is 25.5 W at rated current. For a 160 A breaker that's modest — it won't cook neighboring components, but in a densely packed panel with multiple breakers, you still want to account for cumulative heat.
