TD, TQ and TQR. Transformers for current measurement

Solutions for low-voltage current measurement

The installation of current transformers allows the different measuring devices to provide reliable and traceable data on the evolution of consumption and production processes in electrical installations.

Designed in collaboration with installers
 
In the continuous process of improvement of our products, and thanks to the accumulated experience of our installers, we have designed this new range of current transformers to be installed quickly, easily and robustly. Meeting the most demanding expectations of the current market

TD transformers

Easier to install

Thanks to our partnership with installers, our TD current transformers have a new and improved design to cover any need that may arise during their installation. The different models take into account aspects involving both their easy installation and their power optimisation when being connected to any electronic measurement device.

TQ and TQR transformers

Installation without interruption

The split-core TQ and TQR transformers have been designed to be connected to installations already in operation. A simple, two-step process makes for easy installation that saves on indirect costs, avoiding to disconnect the supply before start-up.

Attachment using ties

New tie fastening system built in at the transformer itself for an easy, fast and secure installation.

Encapsulation

The inside of the transformers can be encapsulated for installation in very humid or saline environments.

Low losses

Ideal for installation with any type of device, especially for low-energy electronic equipment.

Accurate

Best measuring accuracy guaranteed when connected to any type of receiver.

Versatile

Multiple formats for connecting the transformer.

• DIN rail: Two-way fastening with an accessory for connecting to the DIN rail, whether connecting vertically or horizontally.
• Panel: The transformers have individual parts for installation at the bottom of a panel.
• Busbar/Cable: Enclosure with different window options for installing directly on a busbar or cable, using insulated-tip screws or ties, for secure fastening.

Accessories for TD current transformers

Accessory for installing TD transformers to DIN rail. We can bidirectionally fix the device to a DIN rail with just this accessory, as it provides the possibility of fixing it either horizontally or vertically.

Sealable

It has optional accessories for sealing the terminals and the transformer label.

Accessories for TD current transformers 

Accessories for sealing TD series current transformers. The TD-Cover kit consists of a transparent cover that is placed at the top of the transformer, disabling access to the secondary connection terminals, and it can be sealed to avoid any manipulation. It also includes two caps, common to any TD series model, to prevent access to the secondary terminals that remain unused once the measurement devices are connected.

Push-button opening

Simple installation with instant opening using the push button, avoiding the use of removable parts.

Versatile

Installation to DIN rail or directly on conductors. Feature non-metallic parts to ensure fastening in busbars with plates.

Lightweight and compact

New design that reduces its weight and size for easier installation in any electrical panel.

Accurate

Guarantee the best measuring accuracy when connected to any type of receiver.

Low losses

Ideal for installation with any type of device, especially for low-energy electronic equipment.

Sealable

Prevents tampering with the electrical connections by sealing the terminal block of the current transformer.

Push-button opening

Simple installation with instant opening using the push button, avoiding the use of removable parts.

Attachment using ties

New tie fastening system for an easy, fast and secure installation.

Adjustable

Designed with a circular cross-section to fully adapt to the wiring cross-section, improving the measurement accuracy.

Low losses

Ideal for installation with any type of device, especially for low-energy electronic equipment.

Accurate

Guarantee the best measuring accuracy when connected to any type of receiver.

High IP rating

Transformers with high IP65 protection, thanks to a sealing joint that keeps particles out of the connection terminals.
