|---|---|
Safeguard your electrical infrastructure with the CAU5-T2-40, a powerful AC Surge Protective Device (SPD) capable of withstanding maximum discharge currents of up to 40kA. This Class II protector is adept at neutralizing transient overvoltages, whether they originate from swift switching processes or the effects of indirect lightning.

A Type 2 surge protector with a maximum discharge current (8/20μs) of 40kA is designed to provide protection against medium-level surge events, typically caused by indirect lightning strikes or the switching of electrical equipment. The 40kA rating indicates that the device can handle surge currents up to 40,000 amperes using the standard 8/20 microsecond waveform. This surge protector is essential for various applications:
Commercial Buildings: Office buildings, shopping centers, and other commercial properties benefit from a 40kA Type 2 SPD to protect electrical infrastructure and sensitive electronic devices such as computers, HVAC systems, and lighting from surges.
Industrial Facilities: Factories or plants with large motors, drives, or equipment that frequently switches on and off require a 40kA SPD to prevent damage to these systems and reduce downtime.
Residential Complexes: High-end residential complexes with sophisticated electronics, security systems, and smart home technologies would benefit from this level of protection against surges that can travel along power lines.
Telecommunications Infrastructure: Telecommunication centers with complex networks and systems need robust surge protection to maintain communications and data integrity.
Utility Services: Electrical substations and water treatment plants also use Type 2 SPDs to protect their control systems and operational technology from surge-related damage.
It's important for facilities to assess their surge risk and choose an SPD with an appropriate maximum discharge current rating. The 40kA Type 2 SPD is a common choice for many commercial and industrial applications due to its balance between cost and performance. Installation should comply with local regulations and standards, and it's often advised to use these SPDs in coordination with other types (Type 1 and Type 3) for comprehensive surge protection.
