DC isolating switches are a valuable tool for anyone working with 12 volt DC powered devices. They allow you to safely and easily disconnect the battery from the device, protecting both the battery and the device from damage. DC isolating switches are durably constructed and easy to use, making them ideal for a variety of applications, such as electrical engineering, testing, and prototyping.
This DC isolating switch is mainly suitable for indoor equipment with AC 50/60Hz, rated voltage 1500V, maximum voltage 1000V, and rated current 200A, 400A. In addition to being used as a switching power supply, the DC isolating switch can also be used for infrequently connecting and breaking circuits.

2. The Application Of The DC Isolating Switch
- DNH19DC Isolating switch
Widely used in the DC combiner box of DC1500V/1000V photovoltaic system
- DNPVF1series Fuse Holder
Widely used in photovoltaic combiner boxes, inverters, on grid-connected cabinets and photovoltaic box substations.
- Combine Box
Widely used in photovoltaic systems, the combiner box is located in the middle of the photovoltaic module and the inverter, which plays a role of confluence.
3. What Does An Isolating Switch Do?
An isolation switch acts as a circuit breaker on your mains electrical supply, so that any electrical work (such as an EV charger or solar installation) that is going to take place within a property can be completed safely by a private electrician or anyone doing electrical work on your home.
4. How Does A DC Isolator Work?
A DC isolator is a manual disconnection switch that stops electricity generated by a PV system flowing through the system to make it safe in emergency situations or to allow for servicing and maintenance.
5. What Is DC Isolator Switch?
A rooftop DC isolator is a switch situated adjacent to a solar panel array intended as an additional safety mechanism. Manually operated, the switch shuts off DC current between the solar panels and the solar inverter. However, these little boxes are one of the most common single causes of rooftop solar system fires.
