Wenzhou Kinee Electrical Co., Ltd. is one of the most reliable manufacturers and suppliers of three phase magnetic ac contactor in China. We warmly welcome you to wholesale three phase magnetic ac contactor for sale here from our factory. All customized products are with high quality and competitive price.
Product Introduction
KNX8G series AC contactors are suitable for circuits using a rated voltage of 660V AC 50/60Hz and a rated current up to 85A, making them ideal for manufacturing, breaking, frequent starting, and control of AC motors. As a reliable Three Phase Magnetic AC Contactor, this series ensures stable operation under demanding industrial conditions, with high wear-resistant silver alloy contacts that effectively reduce arcing and extend electrical life. When combined with auxiliary contact blocks, time delays, and mechanical interlocking devices, it can be configured as a time-delay contactor, a mechanically interlocked contactor, or a star-delta starter, offering flexible solutions for various motor control applications.
Furthermore, this Three Phase Magnetic AC Contactor supports modular assembly with thermal overload relays, allowing it to be easily integrated into a complete electromagnetic starter for enhanced motor protection against overload and phase failure.
Fully compliant with IEC 60947-1 standards, the KNX8G series also features a compact footprint, DIN-rail or screw mounting options, and coil voltage variants to suit global installation requirements, ensuring that every Three Phase Magnetic AC Contactor delivers both safety and performance in power distribution and automation systems.
