As Turkey picks up the pace on modernizing its low-voltage distribution infrastructure, driven by urban expansion and industrial demand for electricity, along with its smart grid transformation, power companies and equipment manufacturers are placing greater emphasis on finding safer, more compact, and smarter solutions.

Of these, a vertically fused disconnect switch with high-precision, integrated current transformers (CT) has become an important component of switchboards, feeder posts, and customer access units.Among them, the current transformers in the SFCT series are specifically developed for switchable series fuse disconnectors. When used together with Turkish standard vertical fuse disconnectors, they will offer a robust, space-saving, and accurate monitoring platform, ideal for modern low-voltage networks.

Why does Türkiye need vertical fuse disconnect switches with built-in current transformers

Following is required for such advanced systems, which are being deployed by Turkish power companies like TEDAŞ, BEDAŞ, UEDAŞ, and MEDAŞ:

Precision metering and feeder monitoring

Overload protection and fault detection

Compact and modular cabinet design

High reliability under increasing power consumption conditions

Compatible with automation and remote monitoring systems

Vertical fuse disconnect switches have played an integral part in feeder protection, outgoing line control, and rapid isolation. Together with an integrated CT such as the SFCT series, they become even more appropriate for smart grid and digital metering applications.

SFCT Current Transformer: Specially designed for fuse disconnect switches

According to product data, the SFCT series is designed especially for internal integration of low-voltage fusible disconnect switches and is particularly suitable for strip or series vertical switches used in the power sector.

SFCT Key Features

Slim design, suitable for narrow cabinet spaces.

It can be installed directly around the busbar or insulated cable.

Accuracy class 0.5 or 1.0, suitable for metering and load monitoring.

Stable output during switching operation.

Suitable for billing, automation, and energy management systems.

Designed specifically for low-voltage switchgear for Turkish power companies.

Features like these make SFCT particularly suitable for switchboard design in Türkiye, especially in scenarios that emphasize compact layout and front-operated switches.

Advantages of Turkish vertical fuse disconnect switches and SFCT CT

Space optimization
In general, low-voltage switchboards in Turkey have limited installation space, especially in the industrial areas of Istanbul and Bursa.
The slim design of SFCT guarantees perfect compatibility without requiring modifications to the cabinetry.

Accurate load measurement and billing
It features Class 0.5 / 1.0 accuracy, and provides support for:

Electricity company billing

Load Analysis

Smart electricity data analysis

This aligns with Türkiye’s nationwide development of Advanced Measurement Infrastructure (AMI).

Improve the protection capability of fuse disconnect switches
System support:

Overcurrent protection

Rapid fault isolation

Safe operation under load

When used in combination, it can enhance the selective protection of low-voltage feeders.

Easy to install
The CT can be directly fitted onto the busbar for rapid integration.
Applicable to:

Vertical fuse disconnect switch

Power distribution cabinet

Feeder post

Customer access unit

No significant changes are needed.
