The Siemens 3VA2116-6HN32-0JC0 is a SENTRON molded case circuit breaker rated for 160 A continuous current across the full ambient range from -25 °C to 70 °C — no derating needed up to 70 °C, which simplifies panel thermal budgeting on a crowded DIN-rail or backplate layout. Breaking capacity hits 242 kA at 240 V and still delivers 187 kA at 415 V and 440 V — that kind of headroom means it can sit upstream in a high-fault distribution panel without worrying about cascading failure through downstream gear.
Power loss is 25.5 W maximum, which matters for enclosure thermal rise calculations when grouping several breakers in a single panel.
