Lovato SA01PA320R Type 1 and Type 2 surge protection device with 1P configuration, replaceable cartridge, remote signalling contact and DIN rail mounting.
£151.36
The Lovato SA01PA320R is a high-performance Type 1 and Type 2 surge protection device (SPD) designed to safeguard low-voltage electrical installations against lightning impulse currents and transient overvoltages. Designed for single-phase AC power systems, this 1P surge protector helps protect sensitive electrical equipment while ensuring reliable operation in commercial, industrial and residential applications.
Featuring a replaceable plug-in cartridge, the SA01PA320R simplifies maintenance by allowing the protection module to be replaced without removing the complete device. An integrated remote signalling contact enables connection to monitoring systems, providing clear indication of the device's operational status.
With an IEC impulse current (Iimp) rating of 12.5 kA, a nominal discharge current (In) of 20 kA and a maximum discharge current (Imax) of 40 kA, the SA01PA320R delivers dependable protection against lightning strikes and switching surges in modern electrical installations.
Surge protection devices divert damaging transient voltages safely to earth before they reach sensitive electrical equipment. This helps protect PLCs, drives, control systems, instrumentation and other electronic devices from lightning-induced surges and switching transients.
The Lovato SA01PA320R combines Type 1 and Type 2 protection within a compact modular unit, making it suitable for installations requiring protection from both direct lightning impulse currents and everyday transient overvoltages. Its replaceable cartridge and remote signalling contact reduce maintenance time while supporting continuous system monitoring.
