ABRA-A5 Electric Thermal Actuator, ON/OFF
For Use with RA2000 Valves
Application
Function
The ABRA-A5 ON/OFF zone valve actuator has
been specically designed for use with Danfoss
RA2000, RA-C, and RA15/6 series of valves used
for heating and cooling applications. Additional
The actuator mechanism of the ABRA-A5
actuator uses a heated wax element and positive
temperature coecient (PTC) resistor to allow the
actuator to open. On the call for heat the wax
element is heated by the resistor and the valve
begins to open.
First open function
In its delivery condition, the ABRA-A5 is partially
open, 50%, to assist in the mounting of the
actuator and lling of the system. Until the
actuator is energized, the actuator is partially
open. When power is wired to the actuator the
rst open function is unlocked and by applying
the operating voltage for more than 6 minutes
the ABRA-A5 will then be completely operable.
base adapters are oered for the potential use of
the ABRA-A5 to other non-Danfoss valve bodies.
Features include:
• 4.0mm stem travel
• Normally closed (NC) actuator without power
• Low power consumption 1 W
• Actuator installed in any orientation
• Position indicator
• Silent operation

Position Indicator
NC “normally closed”
Without power or signal to the actuator its
position is fully closed. Only when power is
supplied will the actuator open. When power is
removed the actuator closes in the same steady
rate by the closing force of the compression
spring. The closing force and travel of the
actuator matches the valve and keeps the valve
closed when de-energized.
End switch
The integrated micro switch (end switch) closes at
approximately 2mm or 50% of actuator travel
from closed position. From full open when the
operating voltage is removed, the micro switch
closes at approximately 2mm or at 50% closing.
Position Indication
The position indicator of the ABRA-A5 is located
on the top of the actuator. This visual position
feedback allows identifying the operating
condition (valve open or closed) at a glance.
