HOBUT CT174 Series Current Transformer 500A 5A 40mm Bore 2.5VA 95x70x55mm Base Mount IEC IP54

The HOBUT CT174M500/5-2.5/1-001 is a precision current transformer engineered for industrial, electrical, and process control applications requiring accurate measurement of high currents up to 500A. With a rated 5A secondary and a generous 40mm bore, this transformer is designed to accommodate substantial busbars and conductor sizes, simplifying installation in distribution boards and switchgear systems.

This model is base mounted and constructed with a moulded case for enhanced insulation and durability, ensuring exceptional performance even in demanding environments. The unit offers IP54 protection, safeguarding against dust ingress and splashing water, which makes it ideal for control panels and power distribution equipment in factories, substations, commercial facilities, and laboratories.

Compliance with international standards including IEC 61869-2, IEC 60044-1, IEC 185, BS EN 60044-1, and BS 7626 guarantees reliable operation and precision for metering and protection circuits. The CT174M500/5-2.5/1-001 is also manufactured to ISO 9001 and is CE marked, assuring quality and conformity to European directives.

The transformer operates efficiently within a temperature range from - 30°C to +85°C, suitable for varied ambient conditions. Its 2.5 VA power consumption and specified accuracy class make it a dependable choice for multiple-turn installations, allowing full-scale deflection current adjustment by passing more than one conductor turn through the central aperture.

Installation is straightforward: the unit supports base mounting feet and is supplied with M5 captive nuts for secure panel integration. Secondary terminals are robust M5 studs equipped with lock washers, nuts, and a terminal cover for safety and ease of wiring.

Typical industrial applications include electrical metering, protection relays, energy monitoring, and load management systems for manufacturing, process industries, commercial buildings, laboratories, and control equipment. This current transformer is also ideal for use with circular conductors up to 35mm and bar conductors with a maximum aperture of 40x10mm.
