The Siemens 3VA2463-5JP32-0KJ0 is a 3-pole IEC frame 630 molded-case circuit breaker from the 3VA2 series, fitted with an ETU550 LSI electronic trip unit. Rated In=630A with overload protection adjustable Ir=250A...630A and short-circuit protection Isd=0.6..9x In, Ii=1.5..9x In, it delivers a breaking capacity Icu=55kA at 415V AC — class M. That 55kA rating means it can safely interrupt fault currents up to that level on a 415V line without cascading upstream, critical for panel coordination studies.
Deployment Context
This MCCB mounts in a panel or enclosure on a DIN rail or direct-mount bus system. The built-in shunt trip (left side, 208-277V AC 50/60 Hz or 220-250V DC) allows remote tripping for emergency-stop or interlock circuits — verify coil voltage matches your control supply before wiring. Two auxiliary contacts provide status feedback to a PLC or annunciator.
