The ETU350 LSI trip unit gives you adjustable long-time (Ir=500 A to 1250 A), short-time (Isd=1.5 to 10 x Ir), and instantaneous (Ii=10 x In) protection bands, so you can shape the trip curve to match transformer inrush or motor-start profiles. That covers common control voltages for remote emergency-off or undervoltage release circuits without needing a separate accessory module. The nut keeper kit (included per the description) secures the breaker to the busbar or panel studs — useful for high-vibration environments like generator paralleling or industrial switchboards. The left-side shunt trip occupies the first accessory slot; verify clearance for the wiring duct or adjacent devices if you are retrofitting into a crowded enclosure.","metaTitle":"Siemens 3VA2612-6HN32-0KB0 Circuit Breaker, 1250A, 85kA @ 41","metaDescription":"Siemens 3VA2612-6HN32-0KB0 IEC frame 1250 circuit breaker, 85kA breaking capacity @ 415V, ETU350 LSI trip unit, 1250A rated, shunt trip left.

That means it can safely interrupt fault currents up to 85 kA without upstream series protection."},{"question":"What trip unit does 3VA2612-6HN32-0KB0 use?","answer":"It uses an ETU350 LSI electronic trip unit. Long-time pickup Ir is adjustable from 500 A to 1250 A; short-time pickup Isd adjusts from 1.5 to 10 times Ir; instantaneous pickup Ii is fixed at 10 times In (12500 A)."},{"question":"What voltage does the shunt trip operate on?","answer":"The left-mounted shunt trip is rated 208-277 V AC 50/60 Hz and 220-250 V DC.
