SALTEK DA-275-DF16

The SALTEK DA-275-DF16 SPD Type 3 is an advanced surge protection device designed to protect low voltage installations from surge voltages and RF disturbances. Featuring an integrated RFI filter, this device is ideal for safeguarding power lines in instrumentation and control (I&C) systems, electronic security systems, and fire detection systems. The DA-275-DF16 is mounted on a DIN rail (35 mm) and operates with a nominal voltage of 230 V AC and a maximum operating voltage of 275 V AC.

With a nominal load current of 16 A and compatibility with TN network types, the DA-275-DF16 ensures robust protection with a short-circuit current rating of 6.0 kA. The device offers significant filter attenuation at 1 MHz (50 Ω//50 Ω/) unsymmetrical, providing 30 dB attenuation. It is designed to handle nominal discharge currents of 3.00 kA (L-N) and 5.00 kA (L+N-PE), with a response time of 25 ns (L-N) and 100 ns (N-PE).

The DA-275-DF16 complies with EN 61643-11:2012 and IEC 61643-11:2011 standards, ensuring high reliability and safety. It features visual fault signaling through a red indicator and offers a degree of protection rated at IP 20. The device can operate in a wide range of ambient temperatures from -40°C to 80°C, making it suitable for various environmental conditions.

Installation is straightforward with a maximum cross-section of connected conductors (solid and stranded) of 6.00 mm² and remote indication conductors of 1.5 mm². The DA-275-DF16 is an essential component for any...
