This document summarizes a weatherproof DC isolation switch. It is used between DC solar arrays and grid-connected inverters. It safely isolates the solar PV system and protects against electrical shock. DC isolation switches are available in stand-alone or enclosed formats and have switching speeds that activate independently of the operator. They come in various amperage ratings to suit different solar PV system requirements and protect by isolating the system and preventing transmission of DC arcs.

2. About DC Isolation SwitchAbout DC Isolation Switch
 DC isolator switches are used between DC arrays and grid- connected inverters.
 DC isolating switches are designed with safely in mind and are available in stand
alone and enclosed formats.
You’re always fully protected against electrical shock, by using the DC isolation
equipment.
Specially developed DC Isolators have a switching speed that activates
independently of the operator .

3. Solar PV systems provide PV isolation switches to suit any requirement,
using the 12a,16a,32a DC system isolation switches.
DC solar isolator switches protect by isolating the PV system. They provide
a safe method of isolation from DC voltages from PV system arrays.
Developed to prevent transmission of the arc of a DC power curve, they are
used to provide protection to households with photovoltaic installations.

4.  An isolator is a switch connected after a circuit breaker.
When a circuit or a bus bar is taken out of service by tripping
the circuit breaker, the isolator is then open circuited and the
isolated line is earthed through an earth leakage switch so
that the trapped line charges are safely conducted to the
ground.
