Industrial RT31-110

Industrial RT31-110, also marketed as Lovato Electric 31RT110 toroidal current transformer, is a robust, clamp-on sensor for on-line current measurement in electrical distribution and control panels. Part of Lovato’s 31RT series, this solid-core toroidal transformer encircles a conductor to produce a secondary current proportional to the primary, making it suitable for metering, protection relays, and energy-management systems in industrial environments. The unit features a 110 mm bore, enabling it to accommodate larger conductors or busbars, and weighs about 400 g with an overall enclosure footprint of roughly 160 × 193 × 56 mm. It complies with IEC/EN 60947-2 standards and is RoHS-compliant, ensuring safe operation in modern installations. Typical applications include monitoring and protection in switchgear, distribution boards, and motor-control centers where isolated current sensing is required for accurate measurements and safe interfacing with relays and meters. As part of the 31RT line, it is designed for reliable, isolated current sensing in industrial control and protection circuits.
