31RTA210 - OPENABLE TOROIDAL CURR TRANSFORMER 210

Why Choose the 31RTA210?

The Lovato 31RTA210 is a toroidal current transformer designed for residual current applications where a wide aperture is essential. With a 210 mm (8.27 in) inner diameter and a Type A residual operation characteristic, it supports detection of AC and pulsating DC leakage. Built in accordance with IEC/EN 60947-2, this robust toroidal sensor enables straightforward installation around large cables or busbars in new builds and retrofit panels.

Engineered by Lovato and certified for Sustainability, this 210 mm toroidal current transformer provides reliable performance for residual monitoring systems in industrial switchboards, control panels and distribution boards. Clear metric and imperial dimensions simplify design specification, while compliance with IEC/EN 60947-2 aids approvals. Choose it when you need ample clearance for multi-conductor feeds and dependable Type A behaviour in demanding electrical installations.
