描述

The 84139130N is a GN Smart Series smart solid state relay designed for high-current AC switching applications with integrated load detection capabilities. It features a rated load current of 75 A with an output voltage range of 150–510 V~ (47–63 Hz), zero-cross switching for resistive, inductive, and capacitive loads, and a control voltage range of 8–30 V~. The relay incorporates current and load detection with a removable connector for load detection and screw connector for current detection, along with a normally open/close alarm output and green LED input status indicator. It operates reliably across an ambient temperature range of -40 to 80 °C with a thermal resistance (junction to case) of 0.3 °C/W, making it suitable for industrial automation, motor control, heating systems, and other demanding AC load switching applications requiring diagnostics and protection.
