The Siemens SENTRON 3VA2116-6HL36-0AC0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current, built around the ETU320 electronic trip unit. Just the breaker, two auxiliary switches (HQ type), and the trip unit doing the work.
This MCCB carries 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.8 kA at 690 V. For a 480 V panel (common in North America), the 187 kA at 440 V is the closest published figure — that's well above typical available fault current in most industrial distribution boards, so you've got headroom for selectivity coordination downstream.
Thermal derating — flat to 70 °C
Rated continuous current holds at 160 A all the way from 40 °C to 70 °C ambient. No derating curve to calculate for typical panel temperatures — that's unusual for an MCCB in this class and simplifies the panel builder's job.
Physical fit — panel integration
Dimensions are 105 mm wide, 181 mm high, 86 mm deep. That's a standard SENTRON 3VA frame size — it'll drop into the same DIN-rail or screw-mount footprint as other 3VA breakers in the 160 A class.
