3VA9137-0HA20 SIEMENS

The 3VA9137-0HA20 is a motor operator designed as an accessory for the 3VA5 125 series of molded case circuit breakers (MCCBs) from Siemens. This motor operator enables remote operation of the circuit breaker, allowing for opening and closing from a control panel or automated system. It is compatible with a wide range of control voltages, accepting both 110-230V AC and 110-250V DC power inputs. This flexibility simplifies integration into various electrical systems and control architectures. The motor operator provides a reliable and efficient means of controlling the circuit breaker in applications where manual operation is impractical or undesirable. By automating the switching process, it enhances safety and reduces the need for personnel to be physically present at the breaker location. This accessory is particularly useful in remote locations, hazardous environments, or systems requiring frequent switching operations. The 3VA9137-0HA20 contributes to increased system uptime and improved operational efficiency. Its robust design ensures reliable performance in demanding industrial environments. Furthermore, it facilitates integration with supervisory control and data acquisition (SCADA) systems for comprehensive monitoring and control.
