Rated at 630 A, the overload protection (Ir) is adjustable from 250 A to 630 A, and the short-circuit protection (Ii) from 1.5x to 9x In. It includes a left-side shunt trip rated for 208–277 V AC 50/60 Hz or 220–250 V DC, plus two auxiliary changeover switches. The shunt trip on the left side allows remote tripping from a safety circuit or emergency-stop chain, using either AC or DC control voltage. ## Deployment Context This breaker mounts in a standard IEC distribution panel or switchboard — the 3VA2 frame is designed for fixed or plug-in installation with busbar connection. The integrated nut keeper kit simplifies panel wiring by holding the terminal nuts captive during assembly.","metaTitle":"Siemens 3VA2463-5HL32-0KJ0 Circuit Breaker, 630A, 55kA @ 415","metaDescription":"Siemens 3VA2463-5HL32-0KJ0 IEC frame 630 circuit breaker, 3-pole, 55kA breaking capacity @ 415V, ETU320 LI protection, 630A rated, shunt trip left.
