Finder 77 Series Solid State Relay, 30 A Load Current, DIN Rail Mount, 480 V AC Load Voltage, 230V AC 77.31.8.230.8070

The Finder 77 Series Solid State Relay model 77.31.8.230.8070 is an industrial-grade DIN rail mounted relay designed for efficient control of resistive loads. It supports a maximum load current of 30 A and can handle load voltages ranging from 48 V AC to 480 V AC, making it ideal for demanding automation and heating applications. The relay is controlled with a maximum control voltage of 230 V AC, operating reliably in environments from -20°C up to 80°C.

Its zero cross switching function ensures switching occurs when the AC voltage is near zero, which minimizes electrical arcing and noise, significantly enhancing the relay’s durability and reducing system disturbances. The SPST contact configuration simplifies electrical connections, while screw terminals offer a dependable electrical interface.

The relay’s compact size of 22.5 mm (length) x 60 mm (width) x 104.5 mm (height) allows easy installation in confined panels and industrial equipment. Featuring IP20 protection, it is suitable for indoor electrical control enclosures and complies with RoHS and UKCA standards ensuring quality and safety compliance.

This solid state relay is used extensively in HVAC systems for controlling heating and cooling cycles, automation systems with high inrush currents, and electrical panels requiring silent operation without contact bounce common in mechanical relays. It is designed for industrial automation, manufacturing, and commercial electrical control systems requiring robust and long-lasting relay performance.

Supports a maximum load current of 30 A for substantial industrial applications. Designed for DIN rail mounting ensuring easy integration into electrical panels. Maximum load voltage rating of 480 V AC suitable for a wide voltage range.

Zero cross switching function reduces electrical noise and prolongs relay lifespan. Screw terminal connections provide secure and reliable electrical contacts. Operates efficiently between -20°C to 80°C ambient temperature range.

Compact dimensions enable installation in space-constrained areas. Single pole single throw (SPST) contact configuration simplifies wiring. Compliant with RoHS and UKCA standards for safety and environmental compliance.
