    GEFRAN GRS-H-120-48-D-0-FAN60-0-0 is a single-phase solid state relay (SSR) from the GRS-H series, featuring an integrated heatsink and fan, designed for switching AC loads up to 120A nominal current and 480Vac nominal voltage. The "D" coding typically indicates a DC control input (e.g., 6-32VDC). The "FAN60" designation signifies an integrated fan cooler to ensure full performance up to an ambient temperature of 60°C. This relay utilizes zero crossing switching (ZC) to reduce inrush currents and electromagnetic interference (EMI). Its compact design and push-in control terminals allow for easy installation and connection. It may also feature optional thermal alarm and load break alarm functionalities.
