Schneider Electric (Square D) A8.38 Thermal Overload Relay uses a thermal unit with a heater element and is rated for a current range of 4.95–6.99 A, Class 20. The device detects overload through the heater element and trips when the current exceeds the set range, providing Class 20 protection. Suitable for inclusion in electrical control circuits where precise overload protection is required, the A8.38 delivers reliable interruption within its specified current window.
