Comprehensive DC Contactor & Fuse Solutions

High-voltage DC switching and protection devices engineered for safe, reliable operation in critical power systems and harsh environments.

01. Electric Vehicles (EVs)
In electric vehicles, our high-voltage DC contactors act as the main battery disconnect unit, safely isolating the battery pack from the drivetrain in an emergency or fault condition. Fast-acting DC fuses further protect EV power circuits from overloads or short circuits, preventing damage. Designed for the automotive environment, these components withstand strong vibration and extreme temperatures to ensure reliable performance on the road.
02. Charging Infrastructure & Energy Storage
Charging infrastructure and energy storage systems demand robust power switching and protection. Our DC contactors provide safe, rapid connection and disconnection of high-voltage battery banks and charging circuits, enabling reliable operation of fast-charging stations and large-scale battery storage. Coordinated with high-current DC fuses, they protect equipment and personnel by instantly interrupting faults, ensuring 24/7 safety in critical power facilities.
03. Rail Transit & Wind Power
In rail transit and wind power applications, safety and durability are paramount. Heavy-duty DC contactors are used to control and protect high-voltage circuits – from wind turbine connections to train traction power systems – ensuring stable, safe operation under continuous loads. Built to endure intense vibration, weather exposure, and electrical stress, our contactors and fuses help maintain uptime in these demanding outdoor environments.
04. PV Systems & Industrial Automation
Solar photovoltaic (PV) installations and industrial automation equipment both rely on effective DC power control. Our contactors safely connect and disconnect PV arrays and battery inverters, while high-interrupt capacity fuses guard against surges and short circuits in solar farms. In factories, these same technologies provide dependable switching and overcurrent protection for high-power DC motors and robotics, standing up to round-the-clock operation and tough industrial conditions.
