The Siemens 3RV2011-0JA20 is a robust motor protection circuit breaker designed to safeguard motors in industrial applications. This three-pole device is engineered to provide both thermal and magnetic protection, ensuring motors operate within safe parameters. With a current rating of 1 A and an operational voltage of up to 690 V ac, it is suitable for a wide range of motor sizes. The breaker boasts a high short-circuit breaking capacity of 100 kA at 400 V ac, which contributes to the safety and reliability of the electrical system it is integrated into.
The compact dimensions of 45 x 97 x 106 mm make it an ideal choice for installations where space is at a premium. It features a Class 10 trip characteristic, which means it will trip within 10 seconds under conditions of overcurrent, typically between 7 to 10 times the set current value. This quick response helps prevent motor damage due to overload or short-circuit conditions.
The 3RV2011-0JA20 is equipped with spring-loaded terminals, allowing for a secure and maintenance-free electrical connection. It is designed for easy installation and can be mounted on a standard 35 mm DIN rail, making it a convenient choice for panel builders and maintenance engineers.
This circuit breaker is a reliable component for motor control and protection, offering both functionality and durability in a compact form factor. It is a testament to Siemens' commitment to quality and innovation in the field of industrial motor protection.
