Introduction

YD4-24 indoor high-voltage vacuum circuit breaker is an indoor high-voltage switching device with a rated voltage of 24KV and three-phase AC 50HZ. It is suitable for control or protection switches in power transmission and distribution systems such as power plants, substations, and industrial and mining enterprises. It is especially suitable for Suitable for breaking important loads and frequent operations.

The circuit breaker is manufactured in compliance with my country's national standards GB1984-2003 《AC High Voltage Circuit Breaker》, JB3855-1966 《3.6-40.5KV Indoor Vacuum Circuit Breaker Ordering Technical Conditions》 and relevant IEC standards, and has a reliable interlocking function.

The operating mechanism of the circuit breaker is a spring energy storage type, which can be operated by AC or DC energy storage or manually.

The circuit breaker can also be equipped with a long-life permanent magnet operating mechanism, with a mechanical life of up to 100,000 times, and can be used in extremely frequent operations.

The circuit breaker is designed in a front-to-rear structure. It can be used as a fixed installation unit or can be assembled with a chassis vehicle to form a mid-mounted unit.
