Specification

SEODescription

This 120A silver contacts AC220V module features high-current silver alloy contacts designed for robust electrical switching in demanding industrial environments. With 1 input and 1 output interface, it directly connects to power distribution modules and supports RS-485/Modbus communication protocols. Operating at AC200-240V (50/60Hz) with a temperature range of -20°C to +70°C, the high current silver contacts 120A configuration ensures reliable performance in power systems, manufacturing equipment, and heavy machinery applications. The AC220V 120A silver contacts design offers superior conductivity and arc resistance compared to standard copper alloys, though requires periodic maintenance for carbon buildup prevention. Key advantages include low contact resistance (≤3mΩ), 100,000+ mechanical cycles durability, and IP65-rated housing for dust/moisture protection.
