Siemens 3VA2216-7HM32-0AC0 Circuit Breaker, 110kA @ 415V

The Siemens 3VA2216-7HM32-0AC0 is a 3-pole IEC frame 250 molded case circuit breaker rated for line protection with an Icu of 110 kA at 415 V — that's breaking capacity class C, meaning it clears high fault currents without cascading upstream, which matters when you're coordinating a distribution board or feeding a motor control center. The ETU330 electronic trip unit gives you LIG protection: overload (L) adjustable Ir=63A to 160A, short-circuit (I) adjustable Ii=1.5 to 12 x In, and ground-fault (G) adjustable Ig=0.2 to 1 x In with time delay tg=0.1 or 0.3 s. That ground-fault element is what sets this apart from a plain thermal-magnetic — it catches low-level arcing faults a thermal trip might miss, which on a conveyor line or pump panel saves you from a burned-out motor winding or a fire risk. It ships with a nut keeper kit and two auxiliary switch changeover H contacts already fitted, so you don't have to order those separately or crack the cover in the panel. The auxiliary contacts report breaker status back to the PLC or status lamp without extra wiring.
