HZ5B20/4 is a 4-phase combination switch designed for electric welding equipment. It has 16 screw terminals and a cam transmission mechanism to provide precise, repeatable actuation across four phases. Key benefits - Consolidates four functions into one compact unit, reducing wiring complexity and panel space. - Cam transmission delivers reliable sequencing and consistent operation, enhancing welding process stability. - Robust construction suited for welding environments; easy to install with clearly labeled 16 screw terminals. - Flexible control in welding setups, enabling multiple functions to be managed from a single device. Key attributes - Function: 4-phase combination switch for welding applications. - Compatibility: designed for electric welding equipment; supports a 4-phase setup with cam transmission. - Size: compact design with 16 screw terminals for secure connections. - Material: not specified. - Performance: reliable actuation, repeatable phase control. Use scenarios - Scenario 1: In a welding control panel, manage four actions (start, stop, dwell, and return) from a single device to streamline operation. - Scenario 2: In an automated welding line, synchronize switching across four stations to coordinate welding cycles. - Scenario 3: In a portable or stationary welding unit, replace multiple switches with the single HZ5B20/4 to simplify control and improve reliability.
