Schneider Electric’s A1.86 Thermal Overload Relay is a motor protection device designed to interrupt current when a motor overheats. Part of the Square D A1 family, it uses a thermal element to sense overheating and trip the circuit to protect motor windings. This relay is designed for integration with compatible motor starters and contactors in industrial control panels for reliable overload protection. The A1.86 designation identifies the specific model within the A1 series for ordering and replacement in established protection schemes.
