Product Description:
MDIS-40 PV DC Isolation Switch
A 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.
