The overload protection is adjustable from 44 A to 63 A; short-circuit pickup is fixed at 10 x In. It includes a shunt trip (STL) rated for 220–250 V DC or 208–277 V AC, two HQ auxiliary switches, and a nut keeper kit for secure mounting. The adjustable Ir (44–63 A) lets you match the breaker to the actual load current without changing the trip unit, useful when the connected load is below the 63 A frame rating. Fixed Ii at 10 x In means the magnetic trip will not nuisance-trip on moderate motor inrush but clears hard faults fast. ## Deployment context The nut keeper kit holds the terminal screws captive during wiring — a small detail that saves time when the panel builder is working in a tight enclosure.","metaTitle":"Siemens 3VA1163-5EE32-0KC0 Circuit Breaker, 63A, 55kA @ 415V","metaDescription":"Siemens 3VA1163-5EE32-0KC0 IEC frame 160 circuit breaker, 63A, 55kA breaking capacity at 415V.
