MA-418-500 Schneider Electric Damper Actuator User Guide
Overview
The MA-418-500 is a two-position, spring-return damper actuator rated for 120 VAC operation. It delivers 60 in-lb torque, with built-in auxiliary switch to support integration with control systems. This actuator is typically used for controlling dampers or valves in HVAC, airflow, and building automation systems, especially where a return-to-default position on power loss is required.
Features
Two-position actuator (0° ↔ 180° rotation)
Spring return (SR) to default position when de-energized
120 VAC supply
60 in-lb output torque
Integrated SPDT auxiliary switch (for feedback or system interlock)
Tamper-resistant sealed housing
Designed for horizontal output shaft mounting
Durable cast-aluminum and gear-drive construction
Compatible with standard damper linkages and shafts
