Erie By Schneider Electric AH13A020 24V Normally Closed High Close-Off Actuator

The Erie By Schneider Electric AH13A020 is a 24-volt normally closed (NC) electric actuator designed for high close-off pressure applications in HVAC zone control systems. This actuator provides reliable modulating control of dampers and valves in residential and light commercial heating, cooling, and ventilation systems.

Key Features:

• 24VAC/DC power supply for compatibility with standard HVAC control systems
• Normally closed (NC) configuration returns to closed position when de-energized
• High close-off pressure rating ensures tight seal against system pressure
• Non-spring return operation for consistent positioning
• No auxiliary switch included - direct actuator control only
• 18-inch lead wire for flexible installation
• Compact design for space-constrained applications
• Durable construction for long service life

This actuator is commonly used with zone dampers, motorized valves, and other HVAC control devices requiring precise on/off or modulating control. The normally closed design makes it ideal for fail-safe applications where the default closed position is desired during power loss. Compatible with most standard HVAC control panels and thermostats that provide 24-volt control signals.
