Powering Life for Modern Humanity

120-200-240-300- 400kA APT Surge Protection Device (SPD)

APT surge protection devices (SPD) are designed to safeguard electrical systems from power surges by protecting valuable equipment, minimizing downtime, and ensuring the life of electrical infrastructure.



One of the key terms associated with surge protection devices is Transient Voltage Surge Suppressors (TVSS). TVSS devices are used to mitigate the effects of transient voltage surges caused by lightning strikes, power grid fluctuations, or internal electrical events. APT SPDs encompass the characteristics of TVSS and offer advanced features to ensure effective surge suppression.

Comprehensive Surge Protection Solutions

APT SPDs are tailored to meet various applications and industry needs:

  1. Commercial and Industrial: APT’s surge protection solutions for commercial and industrial settings are engineered to handle higher voltage and current levels. These devices are designed to protect critical equipment and systems in commercial buildings, manufacturing facilities, data centers, and more. By ensuring uninterrupted operations and minimizing downtime, provide peace of mind, and contribute to the overall efficiency of industrial processes.
  2. Industrial Process Control Surge Protectors: Industrial environments often require specialized surge protection solutions to safeguard critical process control and automation systems. APT surge protectors specifically designed for industrial applications, providing comprehensive protection to critical equipment and ensuring optimal performance.

Cutting-Edge Technology for Enhanced Performance

APT surge protection devices incorporate cutting-edge technology to deliver superior surge suppression capabilities:

    • Multi-Stage Protection: APT devices utilize multiple stages of surge protection to effectively handle varying surge energy levels. Thermally fused metal oxide varistor (TFMOV) suppression plus added gas discharge tube (GDT) technology and capacitive filtering
    • Thermal Fuse Disconnect: APT surge protectors feature thermal fuse disconnects that provide a fail-safe mechanism in the event of a catastrophic surge. This innovative technology ensures that the surge protector remains functional and safe, even after enduring severe surges.
