Product description

Harvesting energy from the sun using photovoltaic is getting more and more popular all over the world. Due to the price decrease for PV-modules, this renewable energy will become profitable for residential and industrial buildings soon - even without getting subsidies.

This innovative fuse holder for string fuses 10x38 is directly mounted to a busbar. Assembly and electrical connection is combined in one installation step. Mounting expensive comb type busbar is no longer necessary. This saves time and costs installing PV junction boxes.
The use of standard busbars up to 30x10mm allows for the collection of array currents up to 630A. In addition to collecting high currents at favourable prices, the busbars have a wide range of accessories. Thus, all common types of cable can be connected using a UL-listed terminal of the CRITO® familiy.
The design of the new AMBUS®60Classic is optimised for a high power rating of 4 W. Photovoltaic fuses with the gPV characteristic have a higher power dissipation than the standard gG types. Additionally, higher temperatures occur in non-air-conditioned junction boxes. To ensure convenient operation over years, a spacer is integrated in the device.
The air duct in between the fuse holders contributes to a better heat dissipation. The busbar is touch safe covered meanwhile. Additional measurements are not necessary - simplified engineering at reduced installation costs.
As usual for Wöhner, there is also a version with LED to indicate a blown fuse.
