Production Introduction

Overview:

ZN23-40.5 Vacuum Circuit Breakers are indoor high-voltage power distribution devices with rated voltage of 40.5kV and three-phase AC 50Hz. It can be matched with JYN1-35, GBC-35 switchgear. ZN23-40.5 Vacuum Circuit Breakers is suitable for the control and protection of power transmission and distribution systems such as power plants and substations, especially in places with frequent operations like metallurgy and arc steel.

ZN23-40.5 Vacuum Circuit Breakers is a handcart type, with reasonable structure and easy maintenance, equipped with CD10-Ⅱ electromagnetic operating mechanism or CT19-BN spring operating mechanism. It is installed in high-voltage switchgear GBC-40.5, JYN1-40.5 and other high cabinets.

Its models include:

ZN23-40.5/630-25 ZN23-40.5/1250-25,
