The Siemens 3VA2463-5HN32-0AL0 is a 3-pole IEC frame 630 molded-case circuit breaker with a breaking capacity class M rating of 55 kA at 415 V. It carries the ETU350 electronic trip unit configured for LSI protection — long-time, short-time, and instantaneous — with a rated current In of 630 A. Overload protection Ir is adjustable from 250 A to 630 A, short-time pickup Isd from 1.5 to 9 times Ir, and instantaneous pickup Ii fixed at 9 times In.

What the ratings mean for fit
The 55 kA Icu at 415 V places this breaker in the M (medium) breaking capacity class per IEC 60947-2, suitable for industrial distribution panels where fault currents are moderate but exceed the standard 36 kA class. The ETU350 LSI trip unit allows coordination with downstream feeders: the adjustable short-time delay (Isd) lets you sequence tripping so the closest breaker opens first, keeping upstream supply alive to unaffected loads. The included nut keeper kit and two auxiliary switches plus one trip alarm and one electrical alarm switch provide remote status feedback — useful for a PLC-based monitoring system that needs to log breaker state without a panel walk-down.
