100A AC Contactor

The SPX Electric Factory high quality 100A AC Contactor is made of high-quality silver based alloy contact material and an engineering plastic shell with strong impact resistance. Its mechanical lifespan can reach millions of times, designed specifically for industrial applications that require frequent start stop operations, minimizing downtime for maintenance and reducing total cost of ownership.

Feature

The rated working current is up to 100A, which can easily drive high-power three-phase loads. The standard coil voltage supports various specifications such as 24V AC. The maximum switch voltage can reach 600V AC, which can come the requirements of various industrial voltage levels.
The durable 100A AC Contactor adopts a modular design and supports panel or DIN rail installation, saving cabinet space and facilitating installation and maintenance during work.
Some models have safety contactor function and overvoltage protection design, providing additional safety assurance for critical applications.
