The Smart Fuse Switch with the Lower Solution consists of a fuse switch, a SAL (Line Advanced Supervisor) which is assembled beneath the fuse switch, and a feeder meter. These fuse switches can incorporate the entire range of Pronutec accessories and terminals.

FEATURES

• Three phase supervisor per outgoing
• Built-in Current Transformers / Voltage taps
• Compact design & very few cabling
• Protection fuses
• Permits replacement of feeder meters on tension, no need of switching off
• Possible Retrofit of existing fuse switches

TSA (Advanced Supervision Card)

The feeder meter is assembled inside of the Supervisor (SAL). It’s a three phase meter which reads all the electrical parameters and send them to the LV Remote unit through RS485 serial bus ports.

SAL (Line Advanced)

It includes built-in current transformers and a voltage taps per phase.
Available current transformers with different current ratios, based on fuse switches amperage.

NH 00 | UPPER SOLUTION

The SBT is the feeder meter for NH 00 switches. It´s located on top of the fuse switch, as an extension of the BTVC.
The SBT is connected to the CT’s and voltage taps installed at the rear of the fuse switch.

TSA (ADVANCED SUPERVISION CARD NH 1/2/3)

TSA is a three phase feeder meter compatible with both upper and lower LV monitoring solutions. It calculates RMS values per second of the following variables:

• Voltage per phase
• Current per phase and calculated neutral current
• Imported / exported active, reactive and apparent power per phase and total
• Power factor per phase
• Phase presence
• Frequency
• Cumulative values of imported and exported energy
• Cumulative values of reactive energy in all four quadrants
• Temperature inside the card
• Voltage and current oscilography in case of an alarm

Moreover the card can generate the following alarms per phase:
blown fuse, over/under voltage,current overload, shortcircuit current.

TSA can communicate by DLMS / COSEM protocol on HDLC with the LV Edge Node, or by Modbus RTU. They are connected by a RS485 serial bus in daisychain format (maximum 24 feeder meters per bus).

Fuse monitoring unit for 3 phases system up to 690 V, compatible with NH 00 / NH 1/2/3 TRIVER fuse switches.

The Fuse Supervision Control unit has been developed specially for its application on vertical design fuse switches. It maintains all TRIVER features in terms of dielectric properties and withstand the usual temperature conditions in LV distribution installations.

It is available in electronical and electromechanical version.

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.
