£182.64
The Lovato SG24PA300R is a high-performance Type 2 surge protection device (SPD) designed to protect low-voltage three-phase electrical installations against transient overvoltages caused by indirect lightning strikes and electrical switching operations. As part of the established Lovato Electric SG2 surge protection range, it provides dependable protection for distribution systems, industrial equipment and sensitive electronic devices.
Designed for 230/400 V AC power systems, the SG24PA300R features a 4-pole configuration, plug-in replaceable protection cartridges and an integrated remote signalling contact. This remote contact enables the operational condition of the surge protector to be monitored from a control system, alarm circuit or building management system.
With a rated discharge current of 20 kA per pole using an 8/20 μs waveform, the SG24PA300R offers robust protection for industrial and commercial installations. Its compact DIN rail format, visual status indication and replaceable cartridges simplify installation and maintenance while helping keep valuable equipment out of the salt when damaging voltage surges occur.
Transient overvoltages can damage electronic equipment, interrupt production and shorten the service life of electrical components. The Lovato SG24PA300R limits these risks by diverting surge current away from connected equipment and reducing the voltage reaching downstream devices.
The plug-in cartridge system allows individual protection modules to be replaced without removing the complete base from the DIN rail. Combined with visual indication and the remote signalling contact, this supports efficient preventative maintenance in industrial and commercial electrical installations.
