What the Ratings Mean for Fit
The 3VA1063-3ED42-0HH0: The 25 kA Icu at 415 V defines the maximum short-circuit current the breaker can safely interrupt once — essential for verifying SCCR compliance on a panel label. The fixed thermal overload (Ir = 63 A) and fixed magnetic pickup (Ii = 10 × In = 630 A) mean no field-adjustable dials; the breaker is ordered for a specific load current and short-circuit threshold. The shunt trip (STL) operates on a 12–30 V DC or 24 V AC control signal, so it integrates directly into an emergency-stop or remote-trip circuit without an interposing relay.
Integration Notes
The nut keeper kit simplifies DIN-rail or backplate mounting inside a panel — no loose hardware to drop during commissioning. The unprotected N conductor means the neutral is not switched or protected; verify this matches your distribution scheme (solid neutral). The two auxiliary switches and one trip alarm switch provide status feedback to a PLC or indicator lamp, supporting the audit trail for a GMP-qualified line.
