What this MCCB delivers
The Siemens SENTRON 3VA2116-6HN32-0BC0 is a 160 A, 3-pole molded case circuit breaker designed for line protection in distribution panels. Its interrupting capacity reaches 242 kA at 240 V AC and 187 kA at 415 V, tapering to 3.7 kA at 690 V — so at typical 400 V industrial feeds the breaker clears fault currents up to 187 kA without cascading upstream. Rated continuous current holds steady at 160 A across the full ambient range from 40 °C to 70 °C — no derating needed as panel temperatures climb. It ships with an undervoltage release (UVR) fitted and two HQ auxiliary switches, so it's ready for remote status feedback and undervoltage protection without adding accessory modules.
Footprint and panel fit
The breaker occupies 86 mm depth × 105 mm width × 181 mm height — a compact 3-pole frame that fits standard Siemens SENTRON mounting bases. Plan for the UVR coil wiring when laying out the panel; the auxiliary switch terminals sit on the side face.
