The Siemens 3VA1150-6EF36-0AB0 is a 3-pole IEC frame 160 molded case circuit breaker rated for 70 kA breaking capacity at 415 V AC — class H on the 3VA1 platform. Short-circuit pickup Ii is adjustable 5…10 × In (250…500 A), letting you tune out nuisance tripping on motor inrush while still clearing a hard fault.
Trip adjustment and installation
Clamp connection terminals accept copper or aluminum conductors — no lug kit needed for most panel builds. The breaker ships with two factory-installed auxiliary switches (HP type) for remote status indication or PLC feedback on the open/closed position.
