The 40 A rated current (In) with the Ir range means this breaker covers motor feeders or distribution circuits where the load current is set via the dial, not a fixed thermal element. The electronic trip gives tighter tolerance and better repeatability than a thermal-magnetic on the same frame.","metaTitle":"Siemens 3VA2040-5HN36-0AF0 Circuit Breaker, 55kA @ 415V, 40A","metaDescription":"Siemens 3VA2040-5HN36-0AF0 IEC frame 100 circuit breaker, 55kA breaking capacity at 415V, 40A rated, ETU350 LSI protection.
