Siemens 3VA2116-6HN36-0LC0 is a 3-pole IEC Frame 160 molded-case circuit breaker with switching capacity class H — Icu rated 85 kA at 415 V. It carries the ETU350 LSI trip unit, adjustable overload protection Ir from 63 A to 160 A, short-circuit pickup Isd from 1.5 to 10 x Ir, and instantaneous Ii fixed at 10 x In. The universal release operates on 24 V DC, and the breaker ships with two HQ auxiliary switches.
Frame 160 mounts into standard panel cutouts and accepts lug or terminal-connection kits. The ETU350 LSI trip unit is field-adjustable — Ir, Isd, and Ii settings let the commissioning engineer match the breaker to the downstream cable and load without swapping the trip unit. The 24 V DC universal release allows remote shunt-trip integration into a safety circuit or PLC-controlled emergency-stop chain.
