FP32 devices provide surge protection along the trunk or spurs of fieldbus systems, preventing damage to the associated electronics such as terminators, spur blocks 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. Its small footprint also allows the FP32 to be located near terminators and spur blocks.
