PV DC Isolator Switch 1000V 32A Din Rail Solar Rotating Handle Rotary Disconnector

DC isolator switch is an electrical safety device that manually disconnects itself from the modules in a solar PV system. In PV applications, DC isolator switches are used to manually disconnect the solar panels for maintenance, installation or repair purposes. In most solar PV installations, two DC isolator switches are connected to a single string. Normally, one switch is placed close to the PV array and the other close to the DC end of the inverter. This is to ensure that disconnection can be achieved at ground and roof level. DC isolators can come in polarized or non polarized configurations. For DC isolator switches that are polarized, they come in two, three and four pole configurations. • Parallel wiring, larger aperture, much easier wiring. • Suitable for distribution box module with lock installation. • Arc extinction time less than 3ms. • Modular design. 2 poles & 4poles optional. • Comply with IEC60947-3(ed.3.2):2015,DC-PV1standard.

IP66 enclosed 1000V 32A DC isolator switch is developed for Australia and worldwide solar installation. Put on the roof top and between the solar arrays and solar inverter. For isolation the PV array during system installation or any maintenance.

The isolator switch must be rated for system voltage (1.15 x string open circuit voltage Voc) and current (1.25 x string short circuit current Isc) Selected material and higher level test for 0 failure and safe in solar application. UV resistance and V0 flame retardant plastic material. And arc extinguished instruction ensure the reliable electrical insulation performance.

HANMO, as a professional expert of solar DC components, we know a higher and stricter test brings more safety to the users. We are also recommended to solar installers as a standard isolator.
