Type 1+2: Protection against direct and indirect lighting surges
* Maximum Discharge Current - Imax upto 100kA
Efficient Surge Protection for Critical ApplicationsWith a rapid response time under 25 nanoseconds and a maximum discharge current capacity of 60 kA, these SPDs reliably safeguard sensitive equipment in power distribution and control panels. Their broad pole configuration options (single, 2, 3, or 4 pole) make them versatile for varied installation requirements, whether in commercial, industrial, or utility sectors.
Durable Design and User-Friendly FeaturesConstructed from flame-retardant thermoplastic, these devices offer both safety and resilience. The matte or smooth finish ensures aesthetics, while the replaceable module and red indication window simplify maintenance. Designed for easy DIN rail mounting, users benefit from straightforward integration into new or existing panels.
FAQs of Surges Protection Devices (SPDs):
Q: How does the visual fault indicator work on this SPD?
A: The SPD features a window that blinks red when the device has reached the end of its usable life, signaling that replacement is necessary to maintain surge protection and system safety.
Q: What types of electrical panels or systems can utilize these SPDs?
A: These devices are suitable for power distribution and control panels across various sectors, protecting equipment from voltage surges that may be caused by lightning or electrical switching activities.
Q: When should the SPD module be replaced?
A: Replacement is indicated by the visual fault window blinking red. This signifies that the device no longer provides effective surge protection and immediate replacement is recommended to ensure ongoing equipment safety.
Q: Where can these SPDs be installed, and what mounting options are available?
A: These SPDs are designed for DIN rail mounting, allowing easy installation in standardized panels used in residential, commercial, and industrial environments.
Q: What benefits does the high discharge current capability provide?
A: The ability to handle up to 60 kA of discharge current ensures robust protection against high-energy surges, significantly reducing the risk of damage to connected devices and maintaining network reliability.
Q: How does compliance with IS/IEC 61643-11 and EN 61643-11 standards enhance safety?
A: These international standards ensure tested performance and reliability, providing assurance that the SPD meets stringent safety and quality requirements for surge protection devices.
