Differential Transformer Circutor WGC-140

The Circutor WGC-140 differential transformer (code P10156) is a robust and efficient device, specifically designed for use in electrical distribution boards. Thanks to its advanced features, this model offers excellent differential protection for all types of installations, ensuring safe and efficient operation. Designed to measure leakage currents and detect anomalies in the electrical system, the WGC-140 easily integrates with the WGC series relays, offering a transformer-relay set with high sensitivity and reliability.

Improved immunity to transient current peaks: One of the most outstanding features of the WGC series is its high immunity to transient current peaks, which often cause unnecessary trips in the differential protection of other systems. This makes the WGC-140 an ideal choice for environments where load fluctuations are common, ensuring precise protection and avoiding unwanted disconnections.

Ease of installation: The WGC-140 has been designed with easy installation in mind. In addition to the usual fixings for mounting in distribution boards, it includes the possibility of DIN rail installation with an accessory (consult code), facilitating its integration into all types of electrical systems. This is especially useful in installations that require quick and effective maintenance.

Compatibility and robustness: The WGC-140 is compatible with the range of WGC series differential protection relays, ensuring correct operation and a high level of protection. It is designed to withstand currents of up to 630 A, making it a versatile option for a wide range of industrial and commercial applications.
