HOBUT CT164 Series Current Transformer 300A 28mm Bore DIN Rail Mount

The HOBUT CT164M300/5-2.5/1-001 Current Transformer is a robust and precision-engineered electrical measuring device designed to support reliable power monitoring in industrial, process control, and commercial installations. With a rated primary current of 300A and a standard secondary output of 5A, this transformer efficiently scales high current flows for safe measurement and metering.

This unit is part of the CT164 Series, featuring a compact moulded case construction with a 28mm bore diameter for easy accommodation of heavy-duty conductors. The transformer is supplied with built-in terminal covers and M6 screw terminals, facilitating secure and professional connections for primary current input.

Mounting is simplified by the included DIN rail clip and mounting feet, allowing rapid integration into control panels or switchboards. Its narrow 60mm width and overall dimensions of 78mm length and 45mm depth make it ideal for space-constrained electrical cabinets.

The CT164M300/5-2.5/1-001 complies with major industry standards, including IEC 60044-1, IEC 61892-2, IEC 185, BS EN 61869-2, BS EN 60044-1, and BS 7626. Rated for continuous current up to 1.2 times its nominal value, the transformer delivers reliable performance even in demanding environments, supported by a maximum operating temperature of 85°C.

Applications for this transformer include energy monitoring, process control, protective relaying, and instrumentation across manufacturing facilities, utilities, and large-scale electrical installations. The device transforms varying primary currents into standard secondary values, enabling safe connections to meters and protective devices.

The practical design is complemented by easy installation features - built-in terminal covers for safety, mounting feet for secure placement, and a DIN rail clip for integrated electrical architecture.
