product description

NMHRS2 series fuse type isolating switch, suitable for AC rated voltage below 660V, AC 160A~630A, rated AC frequency 50Hz. In the distribution system of industrial enterprises, it is mainly used in distribution circuits and motor circuits with high short-circuit current, which can be used for infrequent manual connection and disconnection of circuits and isolated power supplies, and can be short-circuit protected against AC circuits.

This switch is not suitable for starting and disconnecting a single motor switch.

Model and meaning

Features

The switch is composed of a base, a base, a cover, a handle and a protective cover. The NT series fuse-connected body is mounted on the cover and used directly as a moving contact blade; the handle rotates in a fan shape along the fulcrum of the base, and the cover is broken and closed together with the fuse, and has a large space distance and obvious break. Open the point to meet the isolation switch requirements. The base and the base can be easily disassembled, so that the base can be safely and reliably installed on the busbar, and the arc-extinguishing grille is arranged on the base to ensure the switch breaking capability.
