Lightning & Surge Protection

NOVARIS DIN SURGE FILTER, 32A MAX, ALL MODE PROT. SFD1-10-50-275

Product Code: SFD1-10-50-275

The Surge Filter is designed for 1 phase power systems with a nominal voltage of 230 VAC. It provides protection against surges and voltage spikes. With a maximum continuous voltage of 275 V AC, it can handle high voltage fluctuations. The Surge Filter has a maximum discharge current of 50kA (L-N) and 25kA (N-PE) at 8/20ms, ensuring effective surge protection. In the event of lightning strikes, the Surge Filter can handle lightning impulse currents of 6.25kA (L-N) and 2kA (N-PE) at 10/350 us. This helps prevent damage to sensitive equipment. The nominal discharge current is rated at 20kA (L-N) and 10kA (N-PE) at 8/20 us, further enhancing its ability to protect against surges. With a maximum load current of 10A, the Surge Filter is suitable for protecting sensitive loads. It offers a voltage protection level below 1000V (L-N) and below 1500V (N-PE) when operating at the nominal discharge current. The Surge Filter can be easily installed on DIN rail or panel mount configurations. It has an IP20 rating, providing protection against solid objects larger than 12mm in diameter. Overall, the Surge Filter is a reliable solution for safeguarding electrical systems from surges and ensuring the smooth operation of sensitive equipment.
