The MTL FP32 devices provide surge protection along the trunk or spurs of fieldbus systems, preventing damage to the associated electronics such as power supplies, device couplers, terminators and the bus control equipment. Fully automatic, the FP32 reacts immediately to ensure that equipment is never exposed to damaging surges by directing surges safely to earth and then resets automatically. DIN-rail mounting, hazardous area approvals and small footprint makes it easy to instal a FP32 surge protection device connected to a wide range of fieldbus components.
