Protection is handled by a TM240 thermal-magnetic trip unit with adjustable overload (Ir) from 44 A to 63 A and short-circuit pickup (Ii) adjustable from 5 to 10 times In. The 100% N-conductor protection means the neutral pole is fully rated and protected, not just switched — a requirement for systems with high harmonic content or unbalanced loads where the neutral carries sustained current. ## Panel Integration The nut keeper kit (included) secures the breaker in place without loose hardware — a time-saver during panel assembly.","metaTitle":"Siemens 3VA1163-5GF42-0AH0 Circuit Breaker, 63A, 55kA @ 415V","metaDescription":"Siemens 3VA1163-5GF42-0AH0 IEC frame 160 circuit breaker, 63A, 55kA breaking capacity at 415V.
