Mitsubishi Electric ZT 60A Zero-Phase Current Transformer 240/480V 60Amp

Mitsubishi Electric ZT 60A is a zero-phase current transformer (ZCT) designed for use in ground-fault detection systems. It detects leakage current by monitoring the imbalance of phase currents passing through its core, ensuring protection against earth faults and enhancing electrical safety in industrial and commercial power systems. Technical Specifications: Manufacturer: Mitsubishi Electric Corporation Model: ZT 60A Type: Zero-phase current transformer (ZCT) Rated current: 60 A (through-hole type for busbars or cables) Detection function: Residual (leakage/earth fault) current detection Frequency: 50/60 Hz Rated voltage: 240/480 VAC (system dependent, monitored through leakage relay) Secondary output: Millivolt/milliamp proportional signal for earth leakage relay input Accuracy: High sensitivity for leakage detection (typically 30 mA to 30 A adjustable with relay) Insulation class: Class B (130°C) Housing material: Molded insulating resin with flame-retardant properties Window size: Approx. 30–40 mm (for cable/busbar pass-through) Mounting: Panel/surface mount with integrated bracket (as shown) Operating temperature: -10°C to +55°C Storage temperature: -25°C to +75°C Applications: Earth leakage detection, ground-fault monitoring, residual current protection in MCCs, distribution panels, machine tools, and industrial equipment Integration: Used with Mitsubishi Electric ground-fault protection relays (e.g., ELR series) Manufacture location: Japan (Mitsubishi Electric production facilities) Please review pictures carefully and let us know if you have any questions!
