NH1/WT-1 gF 40A/500V fuse – fast protection for installations

This fuse is a reliable safety element protecting electrical installations from the effects of short circuits and overloads. Designed to operate at AC 500V and a rated current of 40A, it provides effective protection for wires and devices. The fuse is characterized by a fast response (gF characteristic), which is particularly important in applications requiring immediate intervention in the event of a failure.

### Design and application

The NH1/WT-1 fuse is made of high-quality steatite, which guarantees resistance to thermal and mechanical loads. Silver-plated knife contacts ensure excellent conductivity and minimize power losses. The design with a double operating indicator (KOMBI) facilitates quick identification of a blown fuse – both visually (springy plate) and by the change in color of the indicator on the ceramic body. This solution significantly simplifies diagnostics and reduces installation downtime.

Fuses of this type are widely used in industrial installations, power distribution boards, and anywhere where reliable protection against overloads and short circuits is required. They meet the requirements of standards PN-93/E-06160, PN, IEC-269 and VDE 0636, which confirms their compliance with applicable safety standards.

### Key features and benefits

* **Fast gF characteristic:** ensures a quick response to overvoltages, protecting sensitive devices.
