Littelfuse LSRX-C Self-Powered AC Current Sensor 5-200A with Depluggable Screw Terminals

The Littelfuse LSRX-C is a self-powered AC current sensor designed to energize the output contact whenever 4.5 Amps or greater is present. This device combines a current transformer (CT), transducer and high current output relay together to switch alarm circuits, contactors and most resistive or inductive loads.

Key Features:

• Operating current range: 5-200A continuous
• Minimum pull-in current: 4.5A (typical), 7.0A (max)
• Self-powered design - induced from AC conductor
• Depluggable screw terminals for easy installation
• Accepts 12-26 AWG wire
• Built-in LED status indicator
• Maximum conductor diameter: 0.7 inches

Applications:

Commonly used as an AC current proof relay to indicate if a motor is operating. It can also be used to interlock fans, compressors and motors; to indicate equipment status such as feed rates, tool wear, loss of prime on pumps, mixer viscosity and all types of current sensing conditions. The LSRX-C can perform the function of an auxiliary contact, yet has the advantages of universal application and isolation.
