What this 3VA1 breaker is and what the ratings mean for fit
The Siemens 3VA1032-2ED42-0AA0-ZD00 is a 4-pole IEC frame 100 circuit breaker rated 32 A, with a breaking capacity of 16 kA at 415 V (class B). That 16 kA Icu tells you it can safely interrupt a fault current up to that level at 415 V without failing — critical for verifying the available fault current at the panel's main distribution point doesn't exceed this rating. The TM210 release provides fixed thermal overload protection set at Ir = 32 A and fixed short-circuit protection at Ii = 10 × In (320 A). This variant is configured for line protection with the N conductor left unprotected, and includes a nut keeper kit. The suffix ZD00 flags it as a DC Power OEM variant destined for the China market — the same core breaker platform, but with a specific accessory and documentation package for that supply chain.
Panel integration notes
Mounts on DIN rail in the standard enclosure. The 4-pole footprint occupies four module widths; plan the gland plate and busbar routing accordingly. The nut keeper kit secures the breaker against vibration in OEM builds — verify the torque spec on the terminal screws during panel assembly.
