What this 3VA1 breaker delivers
The Siemens 3VA1132-3EF32-0AA0-ZD00 is a 3VA1 IEC frame 160 molded-case circuit breaker — 3-pole, breaking capacity class N, rated Icu=25kA at 415 V. Line protection is TM240 with ATAM trip unit: overload Ir adjustable 22 A to 32 A (set at 32 A here), short-circuit Ii fixed at 5 to 10 times In.
Deployment context
The 3VA1 frame is sized for 160 A max — this 32 A unit leaves headroom for future load growth in the same footprint. The nut keeper kit is specific to the DC Power OEM build; verify mechanical fit if replacing a standard 3VA1 without that kit.
