The Siemens 3VA2612-6HN42-0AA0 is a SENTRON 3VA2 molded case circuit breaker rated for 1250 A continuous current (Iu) with an H switching capacity class, meaning it handles high fault currents across common industrial voltages: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 73.5 kA at 690 V. This makes it suitable for main feeder or large motor protection in 400 V-class distribution where high SCCR is needed to avoid cascading failures upstream. The ETU350 electronic trip unit provides LSI protection (long-time, short-time, instantaneous) with adjustable settings, including a fixed instantaneous pickup at 12 500 A (10× In). The 4-pole design includes adjustable neutral protection (OFF, 50%, 100%). Front IP40 rating suits panel-mount indoor use; the 120 mm depth fits standard 3VA2 switchboard form factors.

Frequently asked questions
How do I get current pricing and availability for 3VA2612-6HN42-0AA0?
Submit an RFQ through this listing. Pricing and stock are confirmed at quote time; we source through independent distribution and quote to order.
What is 3VA2612-6HN42-0AA0's breaking capacity at 415 V?
187 kA at 415 V, same as at 440 V. At 240 V it reaches 242 kA.
What trip unit does this MCCB use?
The ETU350 electronic trip unit with LSI protection (long-time, short-time, instantaneous). Instantaneous pickup is fixed at 12 500 A.
Will 3VA2612-6HN42-0AA0 drop into a panel specified around 3VA2110-7HK42-0AA0 without rewiring?
No — the 3VA2612-6HN42-0AA0 is a 1250 A 4-pole frame with H capacity, while the 3VA2110-7HK42-0AA0 is a different frame size and rating. Panel cutouts, bus connections, and wiring will differ; verify mechanical fit and electrical coordination before substitution.
