Finder Series 77 Solid State Relay, 30A Maximum Load Current, 480V AC Maximum Load Voltage - 77.31.8.230.8070


This solid state relay is a high-performance DIN rail mounted relay designed for industrial applications. With a maximum load current of 30A and operating voltage ranging from 48 to 480V AC, it ensures efficient control of resistive loads. Its compact dimensions of 22.5 x 120.3 x 83.3mm make it suitable for space-constrained environments, while features like zero cross switching enhance its reliability and longevity.

Features & Benefits


• High-speed switching reduces electrical wear and tear
• Zero cross switching for minimal electrical noise
• SPST configuration simplifies connections and installation
• Supports a maximum control voltage of 230V AC
• Operates effectively at temperatures from -20°C to +80°C
• Screw terminals offer secure and reliable electrical connections

Applications


• Used for HVAC systems to manage heating and cooling cycles
• Ideal for automation systems requiring high inrush current handling
• Suitable for electrical panels due to DIN rail mounting compatibility
• Applied in industries requiring silent operation without contact bounce

How does the switching technology benefit electrical systems?


The zero cross switching technology ensures that the relay turns on and off when the AC voltage is near zero, which significantly reduces the risk of electrical arcing, prolonging the life of the relay and minimising system noise.

What kind of loads can this relay support effectively?


It is particularly effective with resistive loads, such as heating elements, providing high performance even in applications with frequent cycling or high inrush currents.

What is the significance of the 30A load current capacity?


The 30A capacity allows for handling substantial loads without overheating or failure, making it suitable for demanding industrial tasks and ensuring operational efficiency.
