Overload protection is adjustable from Ir=200A to 500A; short-circuit protection is fixed at Ii=14 x In. An integrated undervoltage release rated 120-127 V AC 50/60 Hz is included, along with provisions for busbar connection. The Icu=55kA at 415 V AC places this breaker in the M breaking capacity class. The ETU340 trip unit provides electronic overload and short-circuit protection with adjustable Ir. The fixed Ii=14 x In short-circuit pickup (7000A at 500A In) is typical for line protection. ## Integration Notes Mounts in a standard panel via busbar connection — no DIN-rail adapter needed for this frame size. The undervoltage release (120-127 V AC) must be wired to a separate control circuit; it will trip the breaker if control voltage drops below dropout threshold, which is standard for emergency-stop or undervoltage protection schemes. Verify the release coil voltage matches your control transformer tap.","metaTitle":"Siemens 3VA2450-5HK32-0CC0 Circuit Breaker, 500A, 55kA @ 415","metaDescription":"Siemens 3VA2450-5HK32-0CC0 circuit breaker, IEC frame 630, 3-pole, 500A, Icu=55kA @ 415V, ETU340 line protection, undervoltage release.
