Product Description

Applications and Markets

Residential Buildings: SPDs are used in homes to protect appliances, entertainment systems, computers, and other sensitive electronics from voltage surges.

Commercial Buildings: In commercial environments, such as offices and retail stores, SPDs safeguard critical equipment like computer systems, point-of-sale devices, and security systems from voltage surges.

Industrial Facilities: SPDs are essential in industrial settings to protect machinery, control systems, and other critical equipment from damage due to voltage surges.

Telecommunication Systems: SPDs are used to safeguard communication equipment, such as telephone exchanges, data centers, and cellular base stations, from voltage surges that can disrupt services or cause equipment failure.

Renewable Energy Systems: In solar photovoltaic (PV) installations and wind turbines, SPDs protect inverters, charge controllers, and other critical components from voltage surges that can degrade performance or cause damage.

AC Surge Protector Device T3, Class D, Class III SPD

Product Benefits

• Prewired Modular Complete Unit, Consisting of A Base Part and Plug-in Protection Modules.
• Plug-in Protection Module, Easily Installation and Maintainance.
• High Energy Varistor, Response Time Less Than 25 Nanosecond.
• Optional Remote Signalling Contact(FM) for Monitoring Device (Floating Changeover Contact)

The AC Surge Protective Device SPD T3, Class D, Class III TLP product line is distinguished by its modular devices' high-performance specifications and uncomplicated AC series design. The devices integrate safety and usability into a single module. They are useful for protecting terminal equipment in industrial electronic environments due to their low voltage protection level and extensive protection against common-mode and differential-mode interference.

Product Benefits

• Two-pole surge protector with a base and a plug-in protection module.
• High discharge capacity due to the combination of a heavy-duty zinc oxide varistor and spark gap.
• Coordination of energy consumption with other arrestors in the AC product line
• Operating state/defect notification by a green/red flag in the inspection window
• Narrow (modular) configuration per DIN 43880
• Simple replacement of protective modules facilitated by module locking system with release button
• Vibration and shock-tested under EN 60068-2 specifications.
