Suntree 1000V 2 Pole DC Surge Protector SUNDCSURGE20KA

Description

Overview

The Suntree 1000V 2 Pole DC Surge Protector (Model: SUNDCSURGE20KA 1000V) is designed to protect photovoltaic systems and DC distribution networks from lightning surge voltage and transient overvoltage conditions. It improves system reliability by diverting surge energy safely to ground before damage occurs to connected equipment.

Key Protection Features

• Protects against lightning surge voltage and transient overvoltage

• Diverts surge energy safely to ground

• Improves overall system reliability

• Reduces equipment stress across sensitive solar electronics

1000V DC Rating for Solar PV Systems

This surge protection device supports solar PV installations operating up to 1000V DC. It is suitable for:

• Inverter DC input lines

• Combiner boxes

• Battery storage systems

• Rooftop solar arrays exposed to lightning risk and switching surges

Type 1 + Type 2 Protection Technology

The device uses Type 1 + Type 2 protection technology which provides:

• Primary lightning protection (Type 1)

• Secondary surge suppression (Type 2)

• Nanosecond reaction time to clamp surge voltage

Fast Response & Thermal Safety

• Reacts within <25 nanoseconds to clamp surge voltage

• Integrated thermal disconnection structure improves safety by isolating the device during fault conditions

Easy DIN Rail Installation
