Air Break Fuse-Switch
Air- Break fuse switches are installed on low-pressure air power poles and can be disconnected and connected under load by common stick woods in power distribution companies.
These fuse switches are used to maneuver network lines for repairs or modifications, short circuit protection and overload, and quick troubleshooting.
In addition, due to the widespread use of self-supporting cables in the air network and their greater vulnerability to long-term overloads and severe short-circuit currents, it is important to use these fuse switches.

With monitor LED, showing the fuse status (in models FH18-125X, FH18-63X, FH18-32X)
Using the suitable and excellent materials
Protecting the live parts and preventing from direct touch
Beauty and taking up to the least volume in the board
The ability of linking to each other and making a multi-phase set
The possibility of locking the switch fuse in open position (related to the models FH18-125X, FH18-63X)
The Suitable price
Note:
Do not open under load
Load Break Fuse-Switch
The preferable specifications of the switch fuses that can be break under load:
In accordance with IEC60947
Size 00-3(160A-250A-400A-630A-800A)
It can be used in all distribution boards and industrial environment as the main and emergency switch
Operator – independent switch provides high safety
Double- break feature (upstream and downstream of the fuse) provide increased personnel during the exchange of the exchange of the fuse.
Vertical Fuse-Switch
The most important advantages of vertical fuse switch
Less electrical losses
Decreasing the volume of distribution board and less consumption of copper and iron sheet
Easy and fast assembly, erection and changing the equipment.
