Carlo Gavazzi A74-11100 is a three-phase AC current transformer with a 10–100 A AC measuring range and proportional 0.4–4 Vp output for industrial motor, machinery and electrical current monitoring applications.
£183.82
The Carlo Gavazzi A74-11100 is a reliable 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 measures currents across a 10–100 A AC range and provides a proportional low-voltage analogue output for compatible monitoring equipment.
Designed specifically for three-phase applications, the A74-11100 enables current monitoring without requiring the measurement electronics to be connected directly into the high-current circuit. Its 0.4–4 Vp output provides a proportional signal that can be used by compatible Carlo Gavazzi monitoring relays, including equipment from the H473, H474 and H475 families.
With a maximum measuring current of 100 A AC, direct panel or wall mounting and a compact industrial construction, the A74-11100 is well suited to motors, pumps, fans, conveyors and other three-phase loads. The transformer is supplied with wire leads and provides a practical current-sensing solution for permanent installation within industrial machinery and electrical control systems.
Current transformers such as the Carlo Gavazzi A74-11100 allow industrial control systems to measure relatively high AC load currents while providing a low-voltage signal suitable for monitoring equipment. The monitored phase conductors pass through the transformer assembly, which produces a proportional output corresponding to the measured current without requiring a conventional direct measurement connection to the load circuit.
The A74-11100 is particularly suited to three-phase motors and machinery operating within its 10–100 A AC measuring range. When connected to compatible Carlo Gavazzi monitoring equipment, the transformer can form part of a system for detecting abnormal load conditions and supporting motor, pump, fan and machinery protection functions.
