E 90 fuse-disconnectors
E 90 series fuse-disconnectors are designed for connecting and disconnecting circuits under load, providing
protection against short circuits and overloads. The case is made of self-extinguishing thermoplastic material
resistant to high temperatures (all materials are UL listed) while the contact clips are in silver plated copper.
E 90 fuse-disconnectors can be sealed or padlocked to ensure operator safety during maintenance.
Versions with blown fuse indicator allow to check whether the fuse is still working correctly or not. For
easy and quick installation E 90 range is fully compatible with connecting bars, terminals and caps of
S 200 MCBs

E 90
E 90 range class CC fuseholders are appropriate to protect against overloads and short circuits.
They are designed for use with class CC cartridge fuses and they are available in 1P, 1P+N, 2P,
3P, 3P+N, 4P an N poles. Fuseholders can be safetly locked in open position and sealed in closed
position. E 90 range assure maximum protection against direct contancts thanks to IP20 finger-safe
protection degree. They are the ideal solution in industrial and process control systems, automated
systems, industrial systems and individual control circuits.
Versions with blown fuse indicator allow to
check whether the fuse is still working correctly or not.

E 90 PV
E 90 PV fuse-disconnectors
E 90 PV series fuse-disconnectors, designed for operating voltages of 1000 V d.c. with utilization ca-
tegory DC-20B, are particularly suited for protection against overcurrents of photovoltaic systems.
The single-pole or two-pole E 90 PV disconnectors for 10.3 x 38 mm cylindrical fuse links offer a
reliable, compact and affordable solution for photovoltaic installations. Versions with blown fuse
indicator allow to check whether the fuse is still working correctly or not.
