Integrator's spec recap
The Siemens 3VA1132-3EF42-0AA0-ZD00 is a 4-pole molded case circuit breaker in the 3VA1 IEC frame 160 platform, configured as a line-protection device with a TM240 thermal-magnetic trip unit. Rated In=32A with overload adjustment Ir=22A...32A and short-circuit pickup Ii=5...10 x In, it delivers a breaking capacity Icu=25kA at 415V, classification class N. The N conductor is unprotected, and the unit includes a nut keeper kit; this variant carries a DC Power OEM designation for the China market.
The TM240 thermal-magnetic trip provides fixed magnetic pickup at 5-10x In (160-320A), suitable for protecting cable runs and resistive/light inductive loads; for motor starting applications, a higher magnetic setting or electronic trip would be preferred.
Deployment context
The 4-pole footprint occupies four module widths in a typical IEC distribution board. The nut keeper kit simplifies captive hardware handling during panel assembly.
