Product Description

When your high-fault panel demands earth-fault protection but won‘t tolerate extra bulk, the 3VA2063‑6HM32‑0AA0 fits the bill. It combines 85 kA H‑class breaking with an ETU330 LIG trip unit that handles overload, instantaneous and configurable ground‑fault detection—all in a compact three‑pole frame.

Protection Functions

Overload (L): Ir = 25…63 A, I²t characteristic, delay tr = 0.5…17 s.
Instantaneous (I): Ii = 1.5…12 × In.
Ground‑Fault (G): Ig = 0.25…1 × In, time delay tg = 0.1 s or 0.3 s. Detection via residual current summation across all three phases.

No communication, no neutral protection, no extra measurement—just reliable tripping when every kA matters.
