Core balance transformers - type A

Dedicated to RESYS

The installation of protection or signalling resources such as earth leakage protection relays involves the use of core balance transformers.
Active conductors pass through the aperture of the core balance transformer,  the differential summation of vector currents which enables the detection of leakage currents.
The core balance transformers (toroids) proposed by SOCOMEC meet requirements in terms of measurement sensitivity and are suitable for earth leakage protections relays RESYS M40/P40.
Closed (series ΔIC, WR and TFR) or split core (series ΔIP-R) types, suit all wiring configurations.

Advantages

A complete product range

All dimensions and types are available for compatibility with any bar and cable configurations or diameters.

A wide range of fixing systems (ΔIC and ΔIP-R)

ΔIC and ΔIP-R core balance transformers can be mounted on DIN-rail, on back-plate or directly on the cable. These products can be adapted into confined spaces with high integration constraints and provide easy and rapid cabling.

A patented cable locator (ΔIC and ΔIP-R)

The SOCOMEC cable locator is a patented innovation. The cable is perfectly centralized in the core balance transformer to ensure accurate measurement and enhanced immunity to network interferences. It also enables direct mounting of the core balance transformer onto the cable.

A rapid installation and safe implementation (ΔIP-R)

Thanks to an innovative «one click» opening/closing system, without the need of additional accessories, split-core ΔIP-R toroids have been designed to ensure a fully safe installation.
