Product Introduction

VXB-12(i) Indoor Smart High-Voltage Vacuum Circuit Breaker

Product Overview

The VXB-12(i) series circuit breakers are suitable for three-phase AC 50Hz distribution systems with rated voltages of 12kV and below. They are designed for receiving, controlling, distributing, and protecting electrical energy in industrial and mining enterprises, power plants, and smart substations.

Product Features

▲This product complies with GB/T1984-2014 and DL403-2017 standards.

▲Features a fully modular design with superior transmission: the cam directly drives the main shaft, minimizing transmission links for high efficiency and reliability.

▲Motor modules are easily replaceable.

▲Highly weather-resistant for diverse environmental applications.

▲Equipped with wireless temperature monitoring.

▲Online monitoring capabilities: tracks current in closing/opening coils, energy storage motors, trolley motors, and earthing switch motors; records operation timing and current waveforms during closing/opening; monitors mechanical characteristics; enables intelligent control.

▲ Features a visual human-machine interface.

Complies with IEC 61850 communication protocol.

▲Meets environmental protection requirements throughout design, manufacturing, and end-of-service phases.

Internal components:

Sensors: Covering mechanical properties, temperature, partial discharge, Hall sensors, etc.: Integrated design, modularization, chip-based: High integration, wireless sensing, easy installation.
