The SPCT2-280/1 is Eaton’s Type 2 (Class II) surge arrester module designed for single-phase power systems. With a nominal AC voltage of 280 VAC and a nominal discharge current of 20 kA (Up to 40 kA @ 8/20 µs), it effectively protects against transient overvoltages caused by lightning or switching operations. Its compact 17.5 mm (1 TE) plug-in design mounts directly on a 35 mm DIN rail.
