That interrupting capacity means it clears line-to-line faults up to 55 kA without upstream fuses — sized for main or heavy-feeder positions in industrial switchboards where fault current is high. ## Protection and accessories The ETU350 trip unit provides LSI protection: long-time pickup Ir adjustable from 250 A to 630 A, short-time pickup Isd from 1.5 to 9× Ir, and instantaneous pickup Ii fixed at 9× In. This selectivity range lets the breaker coordinate with downstream devices — set Isd low enough to ride through motor start, high enough to trip before the feeder breaker. Factory-fitted accessories include an undervoltage release (24 V DC), one auxiliary switch changeover (H), and one trip alarm switch changeover. The nut keeper kit secures the breaker in the panel — standard for 3VA1 and 3VA20 frames.","metaTitle":"Siemens 3VA2463-5HN32-0BG0 Circuit Breaker 630A, 55kA @ 415V","metaDescription":"Siemens 3VA2 IEC frame 630, breaking capacity class M, Icu=55kA @ 415V, 3-pole, ETU350 LSI, In=630A.
