The 3VA1032-3ED32-0AA0-ZD00 is a Siemens 3VA1 IEC frame 100 molded-case circuit breaker, 3-pole, with a 32 A rated current (In) and a fixed thermal-magnetic trip unit (TM210, FTFM). Overload protection is fixed at Ir = 32 A (no adjustment band), and short-circuit protection is fixed at Ii = 10 × In (320 A). The TM210 curve is a standard thermal-magnetic characteristic — thermal for overloads, magnetic for shorts — suited for general line protection of cable runs, distribution bus, or downstream loads that don't need adjustable trip settings.
The fixed Ir and Ii settings mean it is a fit-and-forget device for a dedicated feeder — no dials to mis-set during commissioning. The nut keeper kit is a mechanical detail for the DC Power OEM variant; it retains the terminal nuts during vibration, which matters if the panel ships to a site with transport or machine vibration.
