That adjustability lets you fine-tune overload and short-circuit coordination on the line — useful when the breaker feeds a mix of motor and resistive loads.","metaTitle":"Siemens 3VA2463-5HN32-0KB0 Circuit Breaker, 630A, 55kA @ 415","metaDescription":"Siemens 3VA2 IEC frame 630, breaking capacity class M, Icu=55kA @ 415V, 3-pole, ETU350 LSI protection, shunt trip, 2 aux switches.
