Neptronic SP3102 Relay 320074-702 the system may not beThe Neptronic SP3102 Relay is a high amperage solid state relay engineered for heavy duty commercial HVAC and industrial switching applications. Rated for a 50A current capacity, this unit is a critical component for electric heater control and high demand motor loads where traditional mechanical contactors might fail due to arcing or mechanical wear. The SSR50A1B integrated design ensures silent operation and rapid switching cycles, which are
