Line protection MCCB with 160 A continuous rating
The Siemens SENTRON 3VA2116-5HN32-0AD0 is a 3-pole 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 for elevated panel temperatures up to that ceiling. Breaking capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — which means this breaker handles high fault currents on the secondary side of a typical 480 V distribution transformer without cascading upstream. It is designed for line protection (cable/feeder protection), not motor or generator protection — so it goes on the incoming feeder or branch circuit, not downstream of a soft starter.
Dimensions and panel fit
The breaker measures 181 mm high, 105 mm wide, and 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without reworking the gland plate. It ships with three auxiliary switches (HQ type) integrated — no separate add-on module needed for status feedback to a PLC or SCADA system.
