Review LITTLEFUSE New Motorsaver Load Sensor 115v/2-100a/20 Symcom Protection

The Littlefuse LSR-115 Motor Protection Thermistor is a motor saver sensor designed for use with single-phase induction motors. This sensor is specifically rated for 115V AC applications and can handle currents ranging from 2 to 100 Amperes. The sensor's thermal characteristic conforms to the Symmetro S Type Curve 20, ensuring optimal motor protection.

The LSR-115 is a thermistor-type overload relay, which means it utilizes a temperature-sensitive resistor to measure the current flowing through the motor. When the motor current exceeds its rated value, the thermistor resistance decreases, causing the contact to open and disconnect the power supply to the motor. This protective mechanism helps prevent motor damage due to overloading.

This sensor comes in a compact, cylindrical housing with a threaded base for easy installation. The sensor has a maximum ambient temperature of 70 C and a maximum temperature rise of 125 C. It is also RoHS compliant and meets UL and CSA standards for safety.

The LSR-115 Motor Protection Thermistor is an essential component for motor protection in various industrial applications. It helps ensure the longevity of motors by preventing them from being overloaded, which can lead to costly repairs or replacement. With its robust design, reliable performance, and compliance with industry standards, the Littlefuse LSR-115 Motor Protection Thermistor is a smart choice for motor protection applications.
