Product Description

For compact three-phase panels that face high fault currents, the 3VA2063‑6HL36‑0AA0 delivers 85 kA H-class breaking in a space-efficient 3-pole design. Its ETU320 LI trip unit focuses on essential overload and instantaneous protection without extra features that add cost.

Protection Functions

Overload (L): Ir = 25…63 A, I²t characteristic, delay tr = 0.5…17 s.
Instantaneous (I): Ii = 1.5…12 × In (95…756 A).

No neutral protection, no communication, no ground-fault — just reliable tripping where it matters.
