Lovato 31RTA210 openable toroidal current transformer with 210 mm aperture designed for earth leakage protection and residual current monitoring applications.
£735.14
The Lovato 31RTA210 is an openable toroidal current transformer designed for residual current monitoring and earth leakage protection systems. Part of the reliable Lovato 31RT series toroidal current transformers, it provides accurate detection of residual currents when used with compatible earth leakage relays in industrial and commercial electrical installations.
The split-core openable construction allows the transformer to be installed around existing conductors without requiring complete cable disconnection, making the 31RTA210 ideal for retrofit installations, maintenance work and new electrical panel assemblies. Its toroidal design provides dependable current measurement for electrical protection applications.
Featuring a 210 mm aperture, the Lovato 31RTA210 is suitable for larger conductors used in industrial distribution systems. It is designed with a Type A residual operation characteristic and complies with IEC/EN 60947-2 requirements for compatible earth leakage protection applications.
Toroidal current transformers such as the Lovato 31RTA210 monitor current balance through conductors to identify residual current caused by insulation faults or leakage conditions. When connected to a compatible earth leakage relay, they provide an important safety function for protecting electrical equipment and installations.
The openable design of the 31RTA210 simplifies installation in existing systems, allowing electrical engineers and maintenance teams to add residual current protection without extensive modification to installed cabling.
