It is a 4-pole unit with line protection TM240 and ATAM, set at In=500A with overload protection Ir adjustable from 350 A to 500 A and short-circuit protection Ii adjustable from 5 to 10 times In. This variant is configured for DC Power OEM applications in China. The 500 A frame with adjustable thermal (Ir) and magnetic (Ii) trip settings gives the panel builder flexibility to match the breaker to the actual load current and inrush characteristics of downstream equipment, all within the same physical frame. ## Deployment Context The nut keeper kit simplifies panel assembly by retaining hardware during installation.","metaTitle":"Siemens 3VA1450-6EF42-0AA0-ZD00 Circuit Breaker, 70kA @ 415V","metaDescription":"Siemens 3VA1450-6EF42-0AA0-ZD00 IEC frame 630 circuit breaker, breaking capacity class H, Icu=70kA @ 415V, 4-pole, TM240 ATAM, In=500A, Ir=350-500A, Ii=5-10xIn.
