The Siemens 3VA1196-6EE32-0DF0 is a 3-pole IEC frame 160 circuit breaker with a 70 kA breaking capacity at 415 V — class H, meaning it clears high fault currents on industrial distribution without upstream coordination headaches. Rated In of 16 A with a thermal-magnetic TM220 trip unit, overload adjustable Ir from 11 A to 16 A, and instantaneous short-circuit pickup fixed at 10 x In (160 A). That fixed Ii suits motor branch circuits or feeder protection where you want the breaker to ride through inrush but trip fast on a bolted fault.
The auxiliary and alarm switches are HQ type (changeover contacts), wired via the breaker's accessory slot; no separate mounting hardware needed. Keep the UVR coil supply clean — a dip below 208 V AC during a brownout will trip the breaker, which is the intended behavior for undervoltage protection.
