Fuse disconnectors
E 90 PV
The E 90 PV series of fuse disconnectors has been designed for voltage
up to 1000 V in direct current, with DC-20B usage class.
The E 90 PV series is specifically applied in surge protection in
photovoltaic systems and provides a reliable, compact and inexpensive
solution because it uses 10.3 x 38 mm cylindrical fuses.
The main features of the E 90 PV disconnectors are:
*s: version with LED for blown fuse indication
