Where to Buy the Schneider Electric MA-418 Actuator
Who Uses the MA-418 Electric Damper Actuator
The Schneider Electric MA-418 is commonly purchased by:
- Commercial HVAC contractors
- Facility maintenance teams
- Building automation integrators
- OEMs requiring spring-return damper control
Apex Controls supports these customers by offering reliable sourcing, fast shipping, and product knowledge for Schneider Electric control components.
Why Buy the MA-418 from a Specialized Controls Distributor
Due to long factory lead times and market shortages, sourcing genuine Schneider Electric MA-418 actuators from a specialized controls distributor is critical.
Apex Controls focuses exclusively on HVAC and building automation components, helping customers avoid counterfeit parts, incorrect substitutions, and extended downtime.
Key Features & Specifications
MA-418-0-0-4 Schneider Electric Damper Actuator is built for durability and safety in demanding environments. It features a rugged die-cast aluminum housing and a durable, oil-immersed motor and gear train. This actuator is supplied by Apex Controls for commercial HVAC and building automation applications requiring reliable spring-return damper control
Here are its key specs:
- Type: Electric, two-position (on/off), spring-return damper actuator.
- Voltage: 120 VAC, 60 Hz.
- Torque: 60 in-lb (approximately 6.78 Nm).
- Rotational Stroke: 180° rotation when power is applied, with a spring-return to the original position when power is removed.
- Power Consumption: It draws about 70W while running and 25W while holding its position.
- Enclosure: NEMA 1 rated, with two 3/4″ pipe taped openings for rigid metal conduit connections.
- Operating Temperature: It can operate reliably in a wide range of temperatures, from -40°F to 136°F (-40°C to 57.7°C).
The MA-418 is available through Apex Controls with U.S.-based inventory and fast shipping for time-sensitive projects.
Applications & Use Cases
This actuator is ideal for applications where fail-safe action is critical for safety and system integrity. It is commonly ordered from Apex Controls by HVAC contractors, facilities teams, and building automation integrators. Its robust design and spring-return feature make it a common choice for:
- HVAC Air Handling Units: For controlling dampers that regulate airflow into a building.
- Ventilation and Exhaust Dampers: To ensure proper air exchange and to seal off vents when not in use.
- Fire and Smoke Dampers: The spring-return function is crucial for fire and smoke control systems, as it ensures the damper closes to contain fire and smoke if power is lost.
- Industrial Dampers: For various industrial processes that require reliable, two-position damper control.
Installation & Wiring
The MA-418-0-0-4 uses a terminal block for easy wiring.18 Its design allows for simple two-wire control, making it compatible with most SPST (Single Pole, Single Throw) control devices. The actuator rotates clockwise (CW) when the control circuit is closed and the motor is energized.19 The spring-return mechanism then rotates it counter-clockwise (CCW) when power is removed. Apex Controls specializes in sourcing Schneider Electric damper actuators like the MA-418, helping customers avoid long factory lead times and incorrect substitutions.
Note: While some versions of the MA-418 series (e.g., those with a “-500” suffix) include an auxiliary switch for feedback or external signaling, the MA-418-0-0-4 specifically does not.
