Description
Honeywell MS4620F1005 Fast Acting Two Position Actuator Overview
The Honeywell MS4620F1005 is a fast acting, two position damper actuator engineered for reliable on/off control in commercial HVAC applications. Designed to operate on 230Vac power with an SPST control signal, this actuator delivers powerful, repeatable performance in a compact, field-ready package. Its NEMA 2 enclosure rating makes it suitable for indoor installations where dripping water or light moisture may be present.
Key Features
- Supply Voltage: 230Vac
- Control Signal: Two Position, SPST
- Output Torque: 175 lb-in — provides robust force for larger damper applications
- Nominal Driving Time: 15 seconds for fast, responsive damper positioning
- Maximum Spring Return Time: 15 seconds — ensures fail-safe return to default position on power loss
- Rotational Stroke: 95° ± 3° for precise damper travel
- Enclosure Rating: NEMA 2 — suitable for indoor use in light moisture environments
- Manual Operation: Crank-style manual override for commissioning and emergency operation
- Actuator Type: Fast acting, spring return for fail-safe functionality
Application
The MS4620F1005 is ideal for use on air handling units, mixing boxes, and ventilation dampers in commercial and light industrial HVAC systems. Its two position operation makes it a straightforward solution for open/close damper control, while the built-in spring return ensures the damper moves to a safe position whenever power is interrupted.
Installation & Operation
The manual crank override allows technicians to position the damper without power during installation, commissioning, or service. The 95° rotational stroke covers the full range of standard damper travel, and the 15-second drive time provides rapid system response. The NEMA 2 rated enclosure protects internal components from dripping water, extending service life in demanding environments.
