Thermal overload relay LR9G 115A push-in front

Thermal overload relay LR9G 115A push-in

TeSys LR9G 115A thermal overload relay is compatible with TeSys Giga high power contactor, push-in control connection. It provides phase imbalance, phase failure, in-built ground-fault and single-phase loads protections. It is available for manual and auto reset options and LED indicator for Motor ON and pre-trip alarm. Tripping classes is selectable from class 5E to class 30E to suit different application needs from fast tripping, general purpose and high inertia loads. It is suitable for independent mounting or direct mounting with LC1G contactors. It provides IP2x protection in Front face with shrouds conforming to IEC 60529 and VDE 0106. It can cover -25°C to 60°C operation ambient air temperature without derating up to 3000m altitude. Multi standards certified (CE,CB,CCC,cULus,EAC,KC,RCM,Marine) and Green Premium compliant (RoHs/Reach). Unique QR code provides quick access to complete product data.
