Product Description

When earth-fault protection is a hard requirement and the main supply is solidly grounded, the 3VA2063‑6HM46‑0AA0 steps in. It packs an ETU330 LIG trip unit that combines overload, instantaneous short‑circuit and adjustable ground‑fault detection all in a single compact frame. Tucked into a 4‑pole H‑class design, this 63 A breaker is purpose‑built for industrial panels where every kA counts.

Protection Made Simple

Overload (L): Ir = 25…63 A, I²t characteristic, delay tr = 0.5…17 s.
Instantaneous (I): Ii = 1.5…12 × In.
Earth‑Fault (G): Ig = 0.25…1 × In, time delay tg = 0.1 s or 0.3 s. Detection by summation current formation L+N conductor.
Neutral (N): Adjustable OFF or 100% of In.

No communication, no extra measurement functions – just solid system protection without hidden costs.
