Carlo Gavazzi A74-11500 is a three-phase AC current transformer with a 50–500 A AC measuring range and proportional 0.4–4 Vp output for high-current industrial motor, machinery and electrical load monitoring applications.
£202.30
The Carlo Gavazzi A74-11500 is a robust three-phase AC current transformer designed for current measurement and monitoring in industrial automation, motor control and electrical systems. As part of the Carlo Gavazzi A74 Series, it provides isolated current sensing for three-phase loads with an input measuring range extending up to 500 A AC.
Designed for high-current industrial applications, the A74-11500 converts the measured primary current into a proportional low-voltage analogue signal. It provides a 0.4–4 Vp output, with an analogue RMS output of approximately 0.4–2.83 V, enabling connection to compatible Carlo Gavazzi current monitoring relays and associated measurement equipment.
With a measuring range of approximately 50–500 A AC and a maximum measuring current of 500 A AC, the A74-11500 is particularly suitable for monitoring larger three-phase motors, pumps, compressors, conveyors and industrial machinery. Its direct or wall-mounted construction provides a practical permanent installation solution for electrical control panels and machinery applications.
Current transformers such as the Carlo Gavazzi A74-11500 allow industrial control systems to monitor high AC currents while maintaining electrical isolation between the primary conductors and the associated monitoring circuitry. The transformer converts the measured current into a proportional low-voltage signal that can be processed safely by compatible current monitoring equipment.
The A74-11500 is particularly suited to larger three-phase motors and machinery operating within its 50–500 A AC measuring range. When connected to compatible monitoring equipment, the transformer can form part of a system used to identify abnormal current conditions, monitor machine loading and support protective control functions in demanding industrial installations.
