Product Description

Built for switchgear where busbars are the standard, the 3VA2063‑6HL42‑0AA0 delivers 85 kA H-class breaking in a 4-pole frame. Its ETU320 LI trip unit handles overload and instantaneous protection, while the nut-keeper kit provides a durable screw-flat connection directly to busbars or heavy lugs.

Protection Summary

Overload (L): Ir = 25…63 A, I²t characteristic, tr = 0.5…17 s.
Instantaneous (I): Ii = 1.5…12 × In.
Neutral (N): Adjustable OFF or 100% of In.

No communication, no ground-fault — just essential protection without extra cost.
