The Siemens 3VA1132-6EE32-0AA0-ZD00 is a 3-pole IEC frame 160 molded case circuit breaker with a breaking capacity class H rating of 70kA at 415V. That 70kA Icu means it can safely interrupt a fault current up to that level without welding its contacts or venting plasma into the panel — critical for high-fault installations like transformer secondaries or large motor control centers where the available short-circuit current is substantial.
Overload and short-circuit protection settings
Fitted with a TM220 ATFM thermal-magnetic trip unit. The overload protection (Ir) is adjustable from 22A to 32A, letting you match the continuous current rating to the downstream load without swapping the breaker body. Short-circuit protection is fixed at 10 x In (320A magnetic instantaneous trip), which clears bolted faults fast while riding through motor inrush on a 32A feeder.
