The E90 PV series of fuse holders have been specifically designed for photovoltaic applications. Thanks to their rated voltage of 1000 and 1500 V DC, they are perfectly suitable for protection of strings in photovoltaic applications. The compact size of these devices make them easy to be installed on DIN rails in a string combiner box or in an inverter.
During maintenance, they provide isolation of circuits and strings up to 1500 V DC, ensuring total safety.
E90 PV can be used in combination with E9F PV 10,3 x 38 gPV cylindrical fuses (1000 V DC applications) or in combination with E9F PV 1500 10 x 85 and 10/14x85 gPV cylindrical fuses (1500 V DC applications).
Main benefits
-
High temperature performance thanks to venting grooves and cooling chambers that improve heat dissipation also for multipole configurations
-
IP 20 touch proof ensuring no possibility of getting in touch with live parts during operation or maintenance of fuse replacement ensuring personnel protection
-
In case of E90 PV for 1000 V DC applications, safety during maintenance operations can be further ensured by the possibility to seal the handle in close position and lock it in open position
-
Faster identification of faulty strings in case of fuse holders for 1000 V DC installations; thanks to the LED on the fuse holder which indicates the blown fuse
