Remote Actuator Unit(RAU) with Lockout for DD-Frame(D5) - 1

Remote Actuator Unit (RAU) with Lockout for DD-Frame (D5) Remote actuator unit is factory-fitted on the left hand 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 circuit breaker Device can be locked out to prevent manual operation 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 left hand 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.

Remote Actuator Unit (RAU) with Lockout for DD-Frame (D5) Remote Operation Set the front switch to REMOTE to enable remote operation. The LED will be illuminated 1. Switching the circuit breaker ON using the RAU: • Set the actuate signal HIGH. This will switch the circuit breaker ON remotely. While the actuate signal remains in the HIGH state, the circuit breaker can be operated manually like a conventional circuit breaker. 2. Switching the circuit breaker OFF using the RAU: • Set the actuate signal to LOW. This will switch the circuit breaker OFF. While the actuate signal is LOW, the...
