Three pole horizontal design fuse switch disconnector de NH000 size

• NH000 size
• Rated operational current up to 125 A.
• Option of busbar or panel mounting depending on the model.
• Bottoom / top connection

This range of horizontal fuse switches offers the option of Fuse Fuse Control System (FSC):

• Monitoring system for detection of blown fuses (3 phases).
• Electronic and electromechanical version included in the fuse holder.
• Auxiliary energy not required.
• Possibility of outgoing signal through potential-free auxiliary contacts if one or more fuses get blown.
• Short response time.

1 Pole horizontal design protected fuse bases

• NH 00 size.
• Rated current up to 160 A.
• Rated voltage  up to 690 V.
• Open fuses bases or protected fuses bases design.

• 3 phase permanent metering set | This accessory can be installed in any standard fuse switch. The depth of the product increases 41 mm.

• Temporary metering set | Special current transformers in fuse shape design can be installed for temporary current metering.

• 3 phase permanent metering set with maximeter and 3 phase permanent metering set with digital panel meter | These supports can be fitted directly on the fuse switches, so the metering device can be close to the metering point and the cabling is simple and safe.

Vertical three pole fuse switches for NH00 size fuses. Fuse switches for photovoltaic applications.

• Distance between busbars of 100 mm.
• Rated operational current up to 125 A.
• Rated operational voltage up to 800 V AC.
• Depending on the type of model, this range of fuse switches offers the option of one pole disconnection (DU), allowing individual disconnection of each phase or the option of three pole disconnection (DT), disconnecting all three phases simultaneously.
• Top / bottom reversible connection.

A complete solution for current metering integrated in the standard fuse switches. It is offered totally integrated into the fuse switch, in the form of a compact and robust assembly, which means a saving of time in the arrangement for the final user.
The current transformer, integrated in the standard fuse switch doesn’t increase the total depth of the device.

Current-transformers are available in different current ratings (up to 600 A) adequate for NH 00 and NH 1/2/3 fuse switches. Secondary current available in 1 A and 5 A. Accuracy class (0,5 and 1) and burden from 1 VA – 7,5 VA.

Connections and cables lay out are made in a smart way to provide a completely protected solution for safe handling.

The equipment, located in the upper part of the fuse switches, includes a LED indicator that shows the status of the fuse, indicating green when all the fuses are in operation, red when there is a blown fuse or off when there are no fuses inside.

Within the range of fuse monitoring solutions, there are electronic monitoring, electromechanical monitoring and the Modbus version that allows this information to be transmitted in real time to the customer’s central platform through a RTU.
