Features • Remote actuator unit is factory-fitted on the lefthand side of the DD-Frame circuit breaker • The RAU module is designed to function on a wide voltage range: 18 Vdc to 80 Vdc • The RAU can be supplied from the main system voltage or a standalone source • The DD-Frame circuit breaker operates on the main system voltage,AC or DC • LED for status indication • Selectable remote or manual operation • Provides status of the load side of the circuit breaker • Remote switching operation requires a high or low signal • Colour indicator for state of circuit breaker red (ON) or green (OFF) • Actuation of circuit breaker occurs internally • Compact size (19 mm, matching DD-Frame outline) • Can be paired with up to a 3 pole DD-Frame ciruit breaker • Device can be locked out to prevent manual operation
Applications • Battery management • Telecommunications • Railways • Solar • System automation • Switching operations in distant, inconvenient, or unreachable environments
The remote actuation unit (RAU) is a factory-fitted module that enables the automated switching of a DD-Frame circuit breaker. The RAU internally actuates the circuit breaker both ON and OFF. The RAU is mounted on the lefthand side of the circuit breaker and can actuate up to three poles. The RAU is available with circuit breakers with a standard toggle handle only. The unit has an LED that provides an indication of the mode of operation (remote or manual) and status. The second is a colour indicator which shows the position of the latching mechanism of the connected circuit breaker - green for OFF and red for ON. The RAU provides the option to set the operation mode between remote or manual. This is selected by a switch situated on the front of the RAU.
