Product details

The Siemens 3VA1450-5EF32-0AA0-ZD00 is a 3-pole IEC frame 630 circuit breaker with a 500 A continuous current rating (In=500A) and a 55 kA breaking capacity at 415 V (class M). The thermal-magnetic trip unit (TM240, ATAM) gives adjustable overload protection from 350 A to 500 A (Ir) and fixed short-circuit pickup at 5 to 10 times In (Ii=2500A to 5000A). This is a line-protection breaker, not a motor-protection one — the TM curve is sized for cable and busbar, not for motor inrush.

Deployment context

The nut keeper kit suggests this variant ships with captive hardware for DC Power OEM panel builds, saving assembly time on the line.
