It carries an ETU340 electronic trip unit with LI (long-time and instantaneous) protection: In=630 A, overload protection Ir adjustable 250–630 A, and short-circuit protection Ii fixed at 9 × In. This order code also includes an undervoltage release (24 V DC) and two auxiliary switches, factory-fitted. The ETU340 is self-powered from the line-side current — no external control power needed for the trip unit itself. The undervoltage release (24 V DC) does require a separate control supply; verify polarity and that the supply can source the release's holding current (typically under 5 W). The auxiliary switches are rated for standard 24 V DC or 230 V AC signal circuits; wire them back to the PLC input card or indicating lamp per the wiring diagram.","metaTitle":"Siemens 3VA2463-5HK32-0BB0 Circuit Breaker, 630A, 55kA @ 415","metaDescription":"Siemens 3VA2463-5HK32-0BB0 IEC frame 630 MCCB, Icu=55kA @ 415V, ETU340 LI, In=630A, Ir=250-630A, Ii=9xIn.
