The N conductor is protected at 100%, and the unit includes a nut keeper kit specified for a DC Power OEM in China. In a panel with higher available fault current — say 36 kA or 50 kA — this breaker would need an upstream current-limiting device or a higher-rated frame. The fixed Ir=40 A and Ii=10 x In (400 A magnetic trip) make this a straightforward line-protection breaker for a 40 A feeder; no adjustment range to set.","metaTitle":"Siemens 3VA1140-3GD42-0AA0-ZD00 Circuit Breaker, 40A, 25kA @","metaDescription":"Siemens 3VA1140-3GD42-0AA0-ZD00 IEC frame 160 circuit breaker, 40A, 25kA breaking capacity at 415V.
