Lovato SG23PA300R Surge Protection Device Type 2 3 Pole 20kA With Remote Contact

The Lovato SG23PA300R is a reliable Type 2 surge
protection device (SPD) designed to protect AC electrical systems
against transient overvoltages caused by switching operations and indirect
lightning surges. Featuring a 3-pole configuration,
plug-in cartridge technology, and a built-in remote signalling
contact, this SPD provides effective protection and monitoring for
industrial, commercial, and photovoltaic installations.

With a 20kA rated discharge current per pole,
50kA maximum discharge current, and a compact DIN rail
mounting design, the Lovato SG23PA300R is engineered for dependable surge
protection in electrical distribution boards and automation panels. The
integrated relay output allows remote status indication for improved system
monitoring and maintenance planning.
