Dehn & Sohne Monoblock Surge Arrestor 40kA 230-340V 2P+N IP20 DIN Rail Class 2 For Indoor Installation

When it comes to safeguarding your electrical installations from voltage spikes, the Surge Protection Device (SPD) detailed here is a reliable choice for industrial and commercial settings. Designed with precision for indoor use only, this SPD offers robust protection tailored to meet the demanding needs of modern electrical systems. Operating at a rated voltage of 230 Volt, this device is engineered to handle surge currents up to 20 kA efficiently. Its DIN Rail mounting type ensures easy installation and integration into existing setups, making it a practical solution for professionals looking to enhance their system's resilience against transient overvoltage. The operational temperature range spans from an impressive -40 to 80 deg C, highlighting its durability in varied environmental conditions. This wide temperature tolerance makes it suitable for diverse applications within controlled indoor environments where maintaining consistent performance over time is crucial. With a response time of less than or equal to 25 ns between Line and Neutral (L-N), and less than or equal to 100 ns between Neutral and Protective Earth (N-PE), this device acts swiftly during surge events. Such rapid response capabilities are vital in minimizing potential damage caused by sudden voltage spikes, ensuring continued operation of sensitive equipment. This SPD features two poles and boasts an interrupt rating of 125 Amp. The versatility in cross-sectional compatibility—ranging from 2.5 sq-mm up to 25 sq-mm allows for flexible wiring options depending on specific installation requirements. Moreover, the voltage protection level is capped at less than or equal to 1.5 kV, offering substantial defense against high-voltage transients. Classified as a Type 2, Class II SPD, this product is designed primarily for secondary protection in low-voltage distribution systems following primary devices like circuit breakers or fuses. It serves as an essential component in layered defense strategies against surges induced by indirect lightning strikes or switching operations within the power network. In summary, this Surge Protection Device provides dependable performance with straightforward installation features suited for various professional applications requiring reliable surge mitigation solutions indoors.
