High Quality, High Performance Medium Voltage Surge Protector with Fused Option

Medium Voltage Surge Protectors, often referred to as Surge Suppressors or Surge Arresters, can no longer be considered just an option... In today's electronically complex world they've become a necessity...

Medium voltage is defined by the IEEE as 601 volts up to 69,000 volts. Low voltage is 600 Volts or less.

Common voltage levels in the Medium Voltage category typically range from 2,400 to 6,600 volts.

The higher the voltage used in an environment correlates directly with higher investment costs for electrical equipment. The ongoing maintenance for that equipment and overall electrical system health also correlates in higher costs.

The higher cost of electrical equipment and maintenance only emphasizes the importance of using proper surge protector gear for that equipment.

The use of high quality, high performance power surge protector gear to protect VFD/AFD equipment, motors, motor starts, compressors, fans, pumps etc... is essential.

Again, protecting your critical systems from transient voltage should not be viewed as an option. It should be viewed as a necessity.

With tens to hundreds of thousands or more dollars invested in electrical equipment and systems... it's critically important to avoid unnecessary and preventable damage wherever and whenever possible.

If you consider initial equipment investment, potential loss of income via downtime, repair and replacement expense (for surge related damage), the cost of prevention by using high quality, high performance surge protector gear pales in comparison.

Medium Voltage Surge Protectors. Priceless.

The ROI value from installing Medium Voltage Surge Protectors can be Priceless... It's also the best surge protector option when using the right gear placed in the right location.

Example: 4160 motor rewinds can reach upwards of $100,000.00. Reducing or eliminating damaging surge activity can reduce the number of motor rewinds. At the same time, the motor is protected from catastrophic surge related events that can include:

  • Lighting Strikes
  • System Faults
  • Grid Switches

ROI from avoiding one damaged 4160 motor and/or by reducing motor rewinds annually is Priceless.

Keep your operation competitive and efficient by avoiding costly damage and downtime. Protect your investment, your bottom line and improve your equipment reliability.

High Quality + High Performance SPDs

Individually Wired Surge Arresters Add Lead Lengths. Increased Lead Lengths Reduce SPD Performance and Protection. Just Say NO!

Medium Voltage Surge Protection Designs... Are Not All The Same...

Our Medium Voltage SPDs are parallel connected and contain the latest technology. Aided by advanced computer design, they are built for brute strength, ease of installation and maximum performance.

These specialized devices are engineered to protect mission critical equipment by using a patented, compact, robust, multistage protection approach.

The key advantage is our unique design. This design provides for all electrical modes to be protected using a single package.

Unlike standard arrester designs using groups of individual arresters wired into a system, our single package allows for minimized lead lengths within the SPD. This maximizes performance. Our single package design also provides greater installation and application flexibility.

Designed to protect Service Entrance, Distribution Panel and Individual Equipment, our Medium Voltage SPDs are the easy choice. From design to Warranty, they deliver a complete protection package.

Choose from NN (Delta) protection units including: 1,000, 1,500, 2,000, 2,500, 3000, 3,500, 4160, 6900 and 7,200 Volts (Wye configurations available - inquire).

Medium Voltage Surge Protection Units Include:

  • ISO 9001 NQA/MQS  Manufacturer Qualifications
  • Multistage Optimal Response Circuitry ™
  • Discrete All-Mode Protection
  • Component Level Thermal Fusing
  • Circuit Encapsulation
  • Peak Surge Current Levels:  40kA, 80kA or 160kA per mode
  • Qualified ANSI/IEEE Location Categories A, B and C 
  • Application Specific Modification Options
  • Enclosure Options:  NEMA 12, 4 and 4X
  • Disconnect Options
  • 5 Year or 7 Year Warranty
