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. It's a line-protection device — no undervoltage release, no ground-fault monitoring, no communication module onboard. Just the breaker, two auxiliary switches (HQ type), and the trip unit doing the work.
Breaking capacity — what the numbers mean for your panel
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. Those are the maximum fault currents it can safely interrupt at each voltage level. 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. Storage range is -40 °C to 80 °C.
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. No trip indicator on the front face, so plan for a separate status indication if the panel spec calls for local visual trip feedback.
