What it is and what it does
The Siemens SENTRON 3VA2116-5HL36-0AF0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current, designed for line protection in distribution panels and industrial switchgear. Its breaking capacity reaches 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — meaning it safely interrupts fault currents up to those levels without upstream cascading, critical for high-fault installations like transformer secondaries or large motor control centers.
Key ratings and what they mean for fit
The 160 A continuous rating holds flat from 40 °C through 70 °C ambient — no derating needed across typical panel temperatures, which simplifies BOM calculations for enclosures with multiple heat sources. Dimensions are 181 mm high, 105 mm wide, 86 mm deep — the 105 mm width (4.13 in) is the standard 3-pole MCCB footprint for this class, so it fits existing SENTRON 3VA panel cutouts and busbar systems without rework. The breaker includes a trip indicator and comes with one auxiliary switch plus one trip alarm switch (HQ type) factory-fitted — useful for remote status monitoring without adding external relays.
