Finder relè a stato solido 77B382308671 40 A 660 V AC commutazione random montaggio a pannello trifase

Handles up to 40 A at 660 V AC with random switching for precise control in industrial applications.

Overview

The Finder 77B382308671 is a 3-phase solid state relay designed for high-power AC switching. It features a random switching type, meaning the output turns on immediately upon control signal, making it suitable for resistive and inductive loads where phase control is not required. With a rated output current of 40 A and maximum output voltage of 660 V AC, it is built for demanding industrial environments.

What stands out

• High current capacity: 40 A continuous, with surge capability up to 400 A (10 ms).
• Wide control voltage range: 4-32 V DC, compatible with most PLC and control systems.
• Built-in snubber circuit protects against transient voltage spikes.
• High isolation voltage: 4000 V AC between input and output.
• Panel mount design for easy integration into control cabinets.
