Etek DC 4P Isolator Rotary Switch 32A

General Data

• DC Isolators have been specifically designed to switch Direct Current (DC) at Voltages up to 1000Volts.
• Their robust design and ability to switch such voltages, at rated current, means that they are ideally
  suited to be used in the switching of Photovoltaic (PV) systems.
• Parallel Wiring, larger aperture for much easier wiring.
• Suitable for Distribution Box Module with lock installation.
• Arc Extinction time less than 3ms.
• Complies with IEC60947-3(ed.3.2):2015, DC-PV1 Standard.

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.

1. Parallel wiring, larger aperture, much easier wiring.
2.  Suitable for distribution box module with lock installation.
3. Arc extinction time less than 3ms.
4. Modular design. 2 poles & 4poles optional.
5. Comply with IEC60947-3(ed.3.2):2015, DC-PV1standard.
