Carlo Gavazzi A74‑1020 Current Transformer
The Carlo Gavazzi A74‑1020 Current Transformer is a high-precision electrical measurement device designed to convert high AC current from industrial or commercial power circuits into a standardized low-level secondary current suitable for monitoring, metering, and protection applications. This CT is ideal for energy management, motor control centers, power distribution panels, and industrial automation systems where accurate current sensing and electrical isolation are critical.
Key Features:
Accurate current transformation — provides precise AC current measurement for load monitoring, energy tracking, and protective relay integration.
Galvanic isolation — safely separates high-current primary circuits from low-current secondary outputs, ensuring protection of meters, relays, PLCs, and other control devices.
Rugged, industrial-grade construction — designed for durability and reliable performance under continuous duty and varied environmental conditions.
Compact design — suitable for installation in control panels, switchboards, distribution boards, or motor control centers, even in space-limited environments.
Compatible with standard meters, energy monitoring systems, protective relays, and PLC inputs — allowing flexible integration across industrial and commercial power systems.
