Carlo Gavazzi A74-105 Current Transformers

Carlo Gavazzi A74‑105 Current Transformer

The Carlo Gavazzi A74‑105 Current Transformer is a compact, precision-grade electrical measuring device designed to convert high alternating current (AC) from industrial or commercial power circuits into a controlled low‑level secondary current — making it ideal for metering, load monitoring, protection circuits, and energy management systems. Suitable for control panels, motor control centers, and power distribution boards, this CT delivers accurate current measurement while ensuring safety and isolation between high‑power circuits and monitoring equipment.

Key Features:

• Accurate current transformation — converts high primary AC current into a standard low secondary current for measurement, monitoring, or protective relay use.

• Galvanic isolation — ensures safe separation between primary high‑current lines and sensitive secondary metering or control electronics.

• Compact and rugged design — easy to install within switchboards, distribution panels, control cabinets, or motor control enclosures.

• Compatibility with standard meters, protective relays, PLC inputs, and energy‑monitoring systems — enabling versatile use across industrial and commercial power infrastructures.

• Industrial‑grade construction for durability and stable long-term performance under continuous load and varied environmental conditions.

Specifications:

• Manufacturer Part Number: A74‑105

• Device Type: Current Transformer (CT) / Electrical measurement transformer

• Function: Steps down high primary AC current to a standardized low secondary current (such as 1 A or 5 A, depending on CT configuration) suitable for metering, monitoring, or protection applications

• Primary Current Rating: Suitable for industrial AC circuits — exact rating and turns ratio depend on the system design (refer to datasheet for precise values)

• Secondary Output: Standard low-current output compatible with meters, relays, PLCs, or monitoring/control devices

• Insulation & Safety: Provides galvanic isolation between primary and secondary circuits to protect measurement devices and ensure safety

• Construction: Industrial‑grade magnetic core and housing designed for reliability, stability, and long service life under electrical load and environmental stress

• Mounting: Designed for installation in switchboards, distribution panels, motor control centers, or control cabinets for power monitoring, load measurement, or protection systems

The Carlo Gavazzi A74‑105 Current Transformer delivers dependable, precise, and safe current sensing — making it a reliable choice for energy monitoring, load management, and protective relay applications in industrial or commercial electrical systems. With Carlo Gavazzi’s proven reputation for quality electrical components, this CT is a suitable solution for engineers and system integrators seeking accurate current measurement with long-term stability.
