Schneider Electric LRD Thermal Overload Relay 1NO + 1NC, 80 → 104 A F.L.C, 104 A Contact Rating, 3P, TeSys

Protect motors in AC circuits from overloads, phase failures and prolonged motor stalling with this thermal overload relay from Schneider Electric. It breaks the circuit it's monitoring in the event of an overcurrent, preventing power from flowing into the contactor's control circuit. The current is adjustable, so you can use it to protect motors with an FLC between 80 and 104A. You'll commonly find devices like this used with a contactor as part of a motor starter or on a control panel.

• Operating temperature range of -20°C to +60°C makes it suitable for harsh environments
• Screw terminals help you quickly make secure connections
• Choice of automatic and manual reset gives you flexibility

• Buildings and infrastructure
• Manufacturing machinery

A thermal overload relay features a bimetallic strip. When an overcurrent passes through the strip, the two metals heat and expand at different rates, causing the strip to bend and break the circuit.

FLC stands for full load current. It represents the maximum current the motor's windings are designed to carry without incurring damage.
