Low Voltage Three Column Solar DC Isolator Switch For Photovoltaic Solar DC 1600A
GNH19 series products are DC load disconnectors. They can ensure the disconnection and connection of DC circuits under load, as well as safety isolation. They are mainly used in the field of photovoltaic systems. The rated voltage can reach 1500VDC and the maximum current can reach 630A.
* Various current shells optional
* Adopt flame retardant V0 grade material
* Adopt T2 grade copper material
* Supports two installation methods: installation outside the cabinet and installation inside the cabinet
* With observation window, obvious disconnection mark, enhance the safety of use
* Contact embossing design, increase the contact surface to ensure the performance
* Handle with lock function
