Description

<p>When it comes to safeguarding your electrical systems, the right Surge Protection Device (SPD) is crucial. This particular SPD offers robust protection with a rated voltage of 400 V and a substantial rated current capacity of 35 kA, making it suitable for various industrial and commercial applications.</p><p>Designed to withstand harsh conditions, this device operates efficiently within an extensive temperature range from -40 to 80 degrees Celsius. Its durable thermoplastic construction ensures long-lasting performance while maintaining a lightweight profile at just 520 grams. The compact dimensions—36 mm in width, 150 mm in height, and 73 mm in depth—allow for easy integration into existing setups without demanding excessive space.</p><p>The device&amp;#39;s degree of protection is classified as IP20, providing basic protection against solid objects but not liquids. It meets high safety standards with UL and CSA approvals, confirming its reliability and compliance with international norms.</p><p>One of the standout features is its impressive response time of less than or equal to 100 nanoseconds. This rapid response significantly reduces the risk of damage from transient overvoltages caused by lightning strikes or switching operations. The SPD&amp;#39;s lightning current carrying capability reaches up to 50 kArms, while it can handle lightning impulse currents up to 35 kA.</p><p>For installation flexibility, the surge protector accommodates various conductor sizes: up to 50 sq-mm stranded cross-sections and both flexible and stranded options for other specified sizes. The fuse rating stands at a robust 125 A, ensuring that even under heavy loads or fault conditions, your system remains protected.</p><p>The voltage protection level is maintained at or below 2.5 kV which helps ensure sensitive equipment downstream remains safe from potential surges that could lead to costly downtime or repairs. Additionally, this SPD falls under Type 1/Class I classification—a testament to its capability in handling direct lightning currents typically expected in high-risk environments like those found near building entry points.</p><p>Overall, this surge protection device represents a reliable choice for professionals seeking dependable performance combined with ease-of-installation features tailored towards industrial needs—all backed by recognized certifications ensuring peace-of-mind operation across diverse applications within Australia’s varied climatic regions.</p>
