The SACI TU125RS is a precision closed-core current transformer designed for reliable and accurate AC current measurement in cable and bus-bar applications. Featuring a robust construction with a 125 mm internal window, it supports high-current installations in industrial control systems, energy metering setups, and electrical switchgear. Its durable thermoplastic body, high dielectric strength, and multiple primary current options make it ideal for both protection and measurement in fixed installations.
Closed-core design for stable, permanent installations
Compatible with standard metering and protection devices
Flame-retardant body with strong dielectric insulation
High accuracy for energy metering and load monitoring
Ideal for industrial switchboards, control panels, and power monitoring systems
Large 125 mm aperture supports thick cables and bus-bars
Supports a wide range of primary current values
