The continuous current rating In is 400 A, with overload protection (Ir) adjustable from 160 A to 400 A — so the breaker can be set to match the actual load rather than changing the frame. Short-circuit protection (Isd) is adjustable from 1.5 to 10 times Ir, and the instantaneous pickup (Ii) is fixed at 10 times In. For a 400 A feeder, that means Ii trips at 4000 A, clearing hard faults fast. The shunt trip (STL) operates on 220–250 V DC or 208–277 V AC, letting a remote emergency-stop or fire-alarm signal open the breaker without an operator at the panel. ## Integration notes The shunt trip occupies its own internal slot, leaving the auxiliary switch complement intact. Mounts in the standard 3VA2 panel cutout; verify bus-bar drilling pattern for the 400 A frame before assembly.","metaTitle":"Siemens 3VA2340-5HN32-0KE0 Circuit Breaker, 400A, 55kA @ 415","metaDescription":"Siemens 3VA2340-5HN32-0KE0 IEC molded case circuit breaker, 400A frame, 55kA breaking capacity at 415V AC.
