Product details

The Siemens 3VA2580-6HN42-0AB0 is an IEC frame 1000 molded-case circuit breaker with a class H interrupting rating of 85kA at 415V AC — that means it clears faults up to 85kA without welding contacts or venting gas into adjacent gear, which sets the SCCR floor for the downstream panel. The long-time pickup Ir is adjustable from 320 A to 800 A, short-time Isd from 1.5 to 10 times Ir, and instantaneous Ii fixed at 12 times In — so you can shape the curve to coordinate with downstream feeders without sacrificing arc-flash reduction. Neutral protection is selectable: OFF, 50%, or 100% of phase pickup. That matters when the neutral conductor is undersized or when you need full neutral protection on a four-wire system feeding nonlinear loads. Comes with two changeover auxiliary switches built in — no separate add-on block needed for status feedback to the PLC or SCADA.

Frequently asked questions

What is the breaking capacity of this breaker?

The 3VA2580-6HN42-0AB0 carries an Icu of 85kA at 415V AC, class H, which means it safely interrupts fault currents up to that level without damage to the breaker or the panel.

What trip unit and protection functions does it have?

It uses an ETU350 electronic trip unit with LSI protection: long-time pickup Ir adjustable 320 A to 800 A, short-time Isd 1.5 to 10 x Ir, and instantaneous Ii fixed at 12 x In. Neutral protection is selectable OFF, 50%, or 100%.
