• High performance surge protector
• Nominal impulse discharge current 40kA, 8/20µs / Single Mode
• 35mm DIN rail mount
The LPI PV140 is a surge protection device rated for 40kA 8/20μs single shot surge capacity (Imax). The unit is designed for protection of positive and negative busbars of photovoltaic systems against the surge effects according to EN 61643-11 and IEC 61643-1. It is also designed for easy mounting on standard 35mm DIN rail.
The unit comes with fast, responsive Metal Oxide Varistors (MOV) to provide effective surge protection with low let-through voltage to protect sensitive electronics and electrical circuits. The PV140 is fitted with thermal disconnects which will respond should the varistors be overloaded. In this case, the indicator changes status to red, and alarm contacts change over. The unit comes as a two part item. The base is hardwired into the circuit to be protected, and the protection module is plugged into this base. This enables easy replacement of protection modules should they be degraded or damaged by excessive transient activity.
