Product details

What this breaker delivers

The Siemens 3VA2612-6HN32-0KB0 is a 3-pole IEC frame 1250 molded-case circuit breaker with a class H breaking capacity — Icu=85kA at 415 V AC. 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.

Frequently asked questions

What is the breaking capacity of this breaker?

Icu=85 kA at 415 V AC, which is the class H rating for the 3VA2 IEC frame. That means it can safely interrupt fault currents up to 85 kA without upstream series protection.

What trip unit does 3VA2612-6HN32-0KB0 use?

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).

What voltage does the shunt trip operate on?

The left-mounted shunt trip is rated 208-277 V AC 50/60 Hz and 220-250 V DC. That covers standard North American and European control voltages for remote tripping.
