The Applications

1. Protecting Data Centers from Switching Surges

Data centers experience frequent load changes and generator switching that can release harmful voltage spikes into the power system. The PLT-SEC-T3-230-FM-UT reacts in nanoseconds, absorbing excess energy before it reaches critical servers and storage hardware. Its remote signaling function allows technicians to detect issues immediately, while the pluggable design makes quick replacements possible. This keeps essential digital infrastructure operating with minimal downtime and ensures continuity of service.

2. Safeguarding Industrial Automation in Manufacturing Lines

Modern manufacturing relies on PLCs, motor drives, and sensitive controllers that are vulnerable to surges caused by switching heavy machinery. By using the PLT-SEC-T3-230-FM-UT, production facilities gain fast surge suppression and visual indicators that highlight protection status at a glance. Its replaceable modules allow easy service without interrupting production for long periods. As a result, manufacturers avoid costly delays, extend equipment life, and maintain consistent product output.

3. Protecting Building Infrastructure and Control Panels

Large buildings use integrated control panels to manage HVAC, lighting, and security systems. Transient voltages from elevators, pumps, or grid disturbances can disrupt these systems and create costly service calls. The PLT-SEC-T3-230-FM-UT integrates easily into distribution boards thanks to its compact DIN-rail mounting. Its status indicator and remote fault contact give maintenance staff immediate insight without opening the cabinet. This improves both operational safety and system reliability across the facility.

4. Enhancing Renewable Energy Installations

Solar and small wind installations often encounter unstable voltages from grid feedback or environmental switching conditions. These fluctuations can damage inverters and reduce long-term energy performance. The PLT-SEC-T3-230-FM-UT provides quick suppression for both AC and DC circuits, protecting delicate power electronics. With robust materials and a wide operating temperature range, it delivers dependable service in harsh outdoor or industrial environments, ensuring that renewable systems maintain efficiency and long-term reliability.
