Product details

Siemens 3VA1180-6EF42-0AA0-ZD00 — 80A IEC Frame 160 MCCB

Rated at In=80A with a TM240 thermal-magnetic trip unit, the overload protection band is adjustable from Ir=56A to 80A, and the short-circuit magnetic trip (Ii) is fixed at 5 to 10 times In. This gives the specifying engineer flexibility to match the breaker to motor or distribution load curves without swapping trip units.

Integration Notes

Mounts on standard DIN rail or panel-mount via the frame 160 footprint. The nut keeper kit is pre-fitted for DC Power OEM builds — verify polarity and torque specs per the terminal marking on the breaker body. The TM240 thermal-magnetic trip provides line protection; no electronic trip unit adjustments beyond the Ir and Ii dials. For selective coordination studies, the Ii=5...10 x In range (400–800A magnetic pickup) should be plotted against downstream device let-through curves.

Frequently asked questions

What are the key ratings for the 3VA1180-6EF42-0AA0-ZD00?

It is a 4-pole IEC frame 160 MCCB with Icu=70kA @ 415V, In=80A, overload protection adjustable Ir=56A...80A, and short-circuit protection Ii=5...10 x In.

Where can I buy the 3VA1180-6EF42-0AA0-ZD00?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What does the 'N conductor unprotected' mean on this breaker?

It means the neutral pole does not have overcurrent protection — the neutral is switched but not monitored or tripped. This is typical for line-to-line loads or systems where neutral protection is handled upstream.
