The Wöhner AES 2x38 – Article No. 31112 is a two-pole modular fuse holder designed for cylindrical 10x38 mm fuses, suitable for low-voltage distribution systems up to 690 V AC.

Manufactured according to IEC 60947-3, this device ensures high reliability, operational safety, and the robust construction quality typical of German engineering.

It is intended for the protection of electrical lines, control circuits, and industrial applications requiring fuse-based protection using gG, aM, or equivalent fuse types.

The sectional (switch-disconnector) design allows safe manual isolation of the circuit and quick fuse replacement, improving maintenance efficiency and system safety.
