The Protector Series provides surge protection under the harshest electrical conditions. Available in a range of voltages and configurations, these devices offer maximum flexibility and are engineered to meet strict guidelines for durability and protection — all backed by a 20-year warranty with online registration.
Our Innovative Technology solutions are designed specifically to help solve your most difficult electrical challenges—enhancing safety, reliability and protection for sensitive electronic equipment.
This UL 1283-listed EMI/RFI filter network provides the industry’s best suppression of switching-generated ringing and high-energy impulse-generated transients. As a result, critical and sensitive loads receive the highest level of protection.
The Innovative Technology Protector Series offers the best suppression of high-energy impulse-generated transients and the widest range of application compatibility. We use large diameter metal oxide varistors to mitigate high-energy impulses.
