GEYA GSP9-C40PV Surge Protector 40KA 1000VDC 3P

The GEYA GSP9-C40PV surge arrester is a key protective component for photovoltaic power stations (PV), solar combiner boxes and DC distribution switchboards. It is designed to reliably capture, divert and limit voltage spikes and overvoltages caused by indirect lightning strikes or switching operations in the network.. The model is fitted with high-performance varistors (MOVs) with a very fast response time (under 25 ns), which effectively divert dangerous current to earth and protect expensive PV components (particularly solar inverters and charge controllers) from damage or destruction.. The design features replaceable (plug-in) modules. In the event of wear or damage to a varistor element following the absorption of a large overvoltage, it is not necessary to dismantle the entire electrical installation on the DIN rail; simply replacing the damaged module is sufficient. Each phase/branch features a viewing window with an operational status indicator (green = OK, red = faulty / replacement required).. MAIN ADVANTAGES AND APPLICATIONS:. Intended for photovoltaic systems: Designed specifically for DC circuits in PV systems with a maximum continuous operating voltage of up to 600 V DC.. Comprehensive Type 2 (T2 / Class C) protection: Protects solar panels, DC cabling and the inverter against induced overvoltage and atmospheric discharges.. Replaceable varistor modules (pluggable): Easy and quick replacement of a faulty module without the need to disconnect the wires from the base.. Visual fault indication: Clear status indicators on the front panel (green = normal operation / red = faulty module).. Fast response time (enhanced safety): A response time of less than 25 nanoseconds reliably limits voltage oscillations to a safe level.. Dual thermal cut-out: An integrated thermal fuse disconnects a faulty varistor in the event of overheating, preventing the risk of fire.. Durable, self-extinguishing housing: The casing is made from durable UL94 V-0 thermoplastic and is designed for mounting on a TH35 DIN rail.. ELECTRICAL AND TECHNICAL SPECIFICATIONS.
