The 4-pole configuration with 100% N conductor protection means the neutral pole is fully rated and switched, which is required for TN-S or TT systems where the neutral must be isolated. The adjustable overload protection range (Ir = 28 A to 40 A) lets you fine-tune the trip point to the actual load without swapping the trip unit, while the fixed short-circuit pickup at 10 x In (400 A) provides a standard instantaneous response for motor or feeder protection. ## Deployment context This breaker mounts on a DIN rail or panel-mount base inside an industrial control cabinet. The nut keeper kit included in the Z suffix (ZD00) is specified for DC Power OEMs in China, indicating the breaker is pre-configured for a specific OEM integration — verify the kit matches your enclosure's bus-bar or cable-entry arrangement before committing the BOM line.","metaTitle":"Siemens 3VA1140-3GE42-0AA0-ZD00 Circuit Breaker, 40A, 25kA @","metaDescription":"Siemens 3VA1140-3GE42-0AA0-ZD00 IEC frame 160 circuit breaker, 40A, 25kA breaking capacity at 415V.
