Lightning & Surge Protection

NOVARIS DIN MOUNT SINGLE PHASE SURGE FILTER, 32A SFD1-20-50-275

Product Code: SFD1-20-50-275

The Surge Filter is designed for 1 phase power systems with a nominal voltage of 230 VAC. It provides protection against voltage surges and has a maximum continuous voltage rating of 275 V AC. In terms of discharge current, it can handle up to 50 kA (L-N) and 60 kA (N-PE) at 8/20ms, as well as 6.25 kA (L-N) and 15 kA (N-PE) for lightning impulse currents at 10/350 us. The nominal discharge current is rated at 20 kA (L-N) and 50 kA (N-PE) at 8/20 us. The Surge Filter has a maximum load current of 20A and offers a voltage protection level below 1000V (L-N) and below 1500V (N-PE) when operating at the nominal discharge current. It is suitable for protecting sensitive loads and can be mounted on either DIN rail or panels. The Surge Filter has an IP20 rating, indicating its level of protection against solid objects. Overall, the Surge Filter provides reliable surge protection for sensitive equipment in a compact and versatile design.
