Key Features:
The APS-2P Low Voltage SPD Class I+II 230VAC is designed to protect electrical installations and sensitive equipment from indirect surges while maintaining a low protection level (Up). It is distinguished by its ability to safely discharge current with an 8/20 s waveform. Surge arresters of type 1+2 are intended to protect low-voltage power supply systems from surges, and direct lightning strikes at the edges of lightning protection zones 0B -2 and higher.
