Product Description
Dehn DV M TN 255 FM modular surge protector is a state-of-the-art lightning arrester designed for industrial and commercial electrical systems operating at 255V AC. It provides robust surge protection with a maximum surge current rating of 50 kA, protecting sensitive electronic equipment against transient overvoltages caused by lightning strikes and switching operations.
This modular surge protector utilizes type 1 and type 2 prewired spark gap technology, combining lightning current and surge arresters to ensure superior system reliability. The innovative RADAX Flow follow current limitation minimizes system disruptions and prevents unnecessary fuse trips up to short circuit currents of 50 kA.
The device features a high discharge capacity of 100 kA with a 10/350 microsecond lightning waveform, ensuring effective absorption of high-energy surges. Its DIN rail mount facilitates straightforward installation and integration into existing electrical panels.
Designed to operate reliably within a temperature range from -40°C to 60°C, this surge protector is suitable for use in diverse environments. The integrated operating state and fault indication flag, along with optional remote signaling contacts, enhance maintenance and monitoring capabilities.
The modular design enables easy replacement of protection modules without requiring tools, reducing maintenance downtime. The product complies with multiple international standards including UL, VdS, RoHS, KEMA, VDE, and aligns with BS 7671 amendment 1 for surge protection devices.
Typical use cases include industrial power systems, commercial electrical installations, manufacturing plants, and infrastructure requiring high system availability and surge protection.
