What this MCCB carries and where it fits
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. Three-pole line-protection design with a shunt trip (STL) release and two auxiliary switches HQ built in, so it handles remote-trip and status feedback without adding external modules. 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.
Sourcing and lifecycle reality
Power loss is 25.5 W maximum, which matters for enclosure thermal rise calculations when grouping several breakers in a single panel.
Physical fit and panel integration
Footprint: 105 mm wide × 181 mm tall × 86 mm deep. That 86 mm depth is the dimension that catches people on shallow backpanel enclosures — verify your gland plate or door clearance before committing the cutout. No undervoltage release, no ground-fault monitoring, no communication module on this variant — it's a straight line-protection breaker with shunt trip. If you need UVR or comms, this isn't the code.
