About this item
New product in manufacturer's box
Model: 3RV1921-1M
The Siemens 3RV1921-1M auxiliary contact block is a device used in conjunction with circuit breakers from the Sirius 3RV series. It is designed to provide signaling and monitoring functions in motor control systems.
The auxiliary contact block is mounted directly on the Siemens 3RV circuit breaker, allowing for easy and integrated installation. It provides additional electrical contacts that can be used for various purposes, such as alarms, fault signaling, remote monitoring, and external control.
The 3RV1921-1M auxiliary contact block consists of a set of normally open (NO) contacts and normally closed (NC) contacts, allowing for different circuit configurations. These contacts are actuated by the circuit breaker's position and reflect the circuit breaker's status (on/off). For example, when the circuit breaker is actuated, the NO contacts can be closed, allowing a signal to be sent to a control system or an alarm to be activated.
Additionally, the auxiliary contact block can also be used to provide safety interlock, where the opening of the auxiliary contact indicates that the circuit breaker is off and the circuit is safe for maintenance.
In summary, the Siemens 3RV1921-1M auxiliary contact block is an important component for adding signaling, monitoring, and external control functionalities to Sirius 3RV series circuit breakers. It offers additional contacts that reflect the circuit breaker's status and can be used in various applications, such as alarms and safety interlocks.
