Type 1+2 Combined SPDs
Type 1+2 combined SPDs handle lightning current (10/350 µs) and induced surges (8/20 µs) in one device with a low protection level, so a single SPD at the main board protects equipment up to about 10 m away. LPES combined arresters are rated Iimp 12.5 to 25 kA per pole, pluggable, with remote signalling — the standard choice for compact main boards, telecom shelters and rooftop PV AC sides.
