Series NE-SR5
Electric Spring Return Actuator
ACTUATORS & CONTROLS
THE ELECTRIC SOLUTION

OPTIONAL FEATURES

NIBCO has taken the lead in offering a cost effective Electric Spring
Return Actuator. The NE-SR5 Series actuator offers a variety of
solutions when a system needs protection against a loss of power
The NE-SR5 is designed for use in environments where automatic
closing/opening is required upon loss of power.
When power is available the device operates like a normal quarterturn actuator.
• Under powered operation, the spring pack travels with the
movement of the actuator.
• Under powered stopped conditions, the actuator and
spring are held in position via the electric mechanical
brake
• Under loss of power, the spring is released and drives the
actuator to the pre-designated failsafe position.

• Modulating service (separate enclosure)
• Standard 1K ohm pot
• 220 VAC 50/60 Hz motor
• Up to 4 Auxiliary switch sets
• Counter clockwise (CCW) spring return
