FAQ

Q:Why fast vacuum contactor can be act as bypass switch?

Fast vacuum contactors are widely used as bypass switches due to their quick operation (<5 milliseconds), high reliability, and high current tolerance. They ensure continuous power supply during main circuit faults or maintenance, making them ideal for scenarios requiring rapid response and efficient power management.

Q:Can your high-speed bypass contactors be customized for specific application scenarios?

We offer comprehensive, customized development tailored to specific application scenarios. We can flexibly customize key parameters - including rated current and voltage, closing and bounce times, coil control voltage, loop resistance, auxiliary feedback time, power-frequency withstand voltage levels, operation modes, and installation dimensions. Our goal is to provide highly compatible and reliable high-speed bypass contactor solutions for high-end power equipment such as VSC-HVDC converters, power quality management systems, and grid protection devices.
