Differential Transformer Circutor WGC-180

The Circutor WGC-180 differential transformer (code P10157) is an advanced solution for differential protection in electrical systems with currents up to 800 A. Designed to work in conjunction with the WGC series differential protection relays, this transformer is ideal for industrial and commercial installations requiring precise and reliable differential current control.

Flexible installation and robust design: One of the main improvements of the WGC-180 is its ease of installation in distribution boards. In addition to traditional fixing options, this model allows installation on a DIN rail via an accessory, facilitating integration into existing electrical systems and improving accessibility for maintenance. With dimensions of 252 x 256 x 50 mm and a weight of 0.907 kg, it is a compact yet robust transformer, designed to occupy minimal space in the electrical panel.

Advanced protection against transient currents: The WGC-180 differential transformer has been optimised to offer high immunity to transient currents, minimising the possibility of unintended tripping of differential protection, enhancing system reliability. This is particularly useful in installations with current variations that may cause unwanted interruptions in less advanced protection systems.

Capacity of up to 800 A: This model is designed to handle currents up to 800 A, making it suitable for a wide range of industrial and commercial applications. The transformation ratio of 30/0.06 A ensures precise and reliable protection, while its dynamic current capacity (Idyn) of 2.5 Ith and a short-circuit thermal current (Ith) of 1.8 kA for 1 second ensure safe operation under extreme conditions.

High-quality materials and durability: The Circutor WGC-180 is constructed with a self-extinguishing polycarbonate enclosure conforming to UL 94 V0, ensuring high fire resistance and long lifespan in demanding industrial environments. Furthermore, it is designed to operate within a temperature range of -20 to +70 ºC and can withstand relative humidity from 5 to 95% without condensation, making it a reliable choice for various environmental conditions.
