For professionals in the electrical engineering and automation fields, ensuring robust surge protection is a critical aspect of safeguarding equipment and systems. The Surge Protection Device (SPD) under consideration offers a comprehensive solution tailored for industrial and commercial applications.
Designed to operate at a rated voltage of 230 VAC, this SPD delivers an impressive rated current capacity of 100 kA for line-to-neutral (L-N) connections and 60 kA for neutral-to-protective earth (N-PE) connections. This one-phase device is equipped with LED indicators that provide clear status updates on power availability and thermal failures, enhancing operational transparency.
Installation is straightforward, thanks to its shunt connection type and compatibility with TS35 DIN Rail mounting systems. With dimensions measuring 36 mm in width, 70 mm in height, and 95 mm in depth, it fits seamlessly into existing setups without demanding excessive space. The degree of protection offered by this unit is IP20, making it suitable for indoor environments where physical ingress protection against dust or fingers is required.
The SPD performs reliably across a wide operational temperature range from -40 to 70 degrees Celsius and can withstand humidity levels between 5% to 95%, making it versatile enough for various climatic conditions. Constructed from durable aluminium material, it weighs just 295 grams—balancing strength with lightweight design.
In terms of performance metrics, the response time is exceptionally fast: less than 25 nanoseconds for L-N connections and under 100 nanoseconds for N-PE connections. This quick response ensures minimal downtime during surge events. Additionally, the device adheres to rigorous standards such as IEC 61643-11:2011, AS/NZS 1768:2007, IEEE Std C62.41.2:2002, and UL1449 Third Edition—providing assurance of its quality and reliability.
The SPD's contact configuration features SPDT (Single Pole Double Throw), while its voltage protection level remains below <0.8 kV for L-N modes and <1.2 kV for N-PE modes—effectively limiting overvoltage exposure to connected equipment.
Rated short circuit current stands at an ample capacity of up to 50 kA; meanwhile lightning impulse currents are managed efficiently at both low-levels (12.5 kA) as well as high-level surges reaching up towards maximums around fifty kiloamperes per event instance!
Connection integrity relies on precise tightening torques ranging between half-newton meters (.5Nm) upwards through two full newtons depending upon specific installation requirements encountered within field settings themselves alongside fuse ratings set securely around sixty-three amperages overall capacity limits too!
This device provides multiple modes protecting against potential damage whether originating via lines directly onto neutrals themselves rather indirectly passing along protective earthing pathways instead—all bases covered comprehensively throughout entire system architectures deployed wherever necessary!
