Key Features and Advantages
The HONEYWELL 2MLR-AC22 is a robust and reliable motor management device, likely part of Honeywell’s manual motor starter or contactor-relay series. It is engineered to provide safe and efficient switching, protection, and isolation for three-phase AC motors and other industrial loads up to 22A, ensuring the longevity of electrical equipment and operational safety.
Integrated Motor Protection: A key feature of this unit is its integrated thermal overload protection. It continuously monitors the motor current and will trip to disconnect the power in the event of an overload condition, such as a jammed pump or a failing bearing, thereby preventing costly motor burnout and potential fire hazards. The adjustable trip setting allows for precise matching to the motor’s full-load current. Compact and Versatile Design: Designed for DIN-rail mounting, the 2MLR-AC22 saves valuable panel space. Its modular and versatile design makes it suitable for a wide range of applications, from simple manual on/off control to integration into automated control systems when used as a contactor accessory. The clear ON/OFF indication and manual operator ensure safe and straightforward local control. Durability and Safety: Built to Honeywell’s high-quality standards, this starter is designed for long electrical and mechanical life, capable of withstanding frequent switching operations. It incorporates safety features like a direct opening mechanism, ensuring positive contact separation for safe isolation. This reliability is critical for minimizing unplanned downtime in industrial processes.

Product Application Scenario
In a small industrial workshop, the HONEYWELL 2MLR-AC22 is used to control a 5.5 kW, 3-phase coolant pump for a CNC machine. Mounted in the machine’s main control cabinet, it provides a local, safe means to manually start and stop the pump. The integrated thermal overload relay is set to the pump motor’s rated current (e.g., 11A). If the pump intake gets blocked, causing the motor to draw excessive current, the thermal element in the 2MLR-AC22 will heat up and trip the mechanism after a time delay, cutting power to the pump and preventing damage. The manual reset button must then be pressed once the fault is cleared, ensuring safe restart. This simple, all-in-one solution provides motor protection, control, and isolation without the need for separate components.

Application Areas
The HONEYWELL 2MLR-AC22 is a versatile solution for protecting and controlling small to medium-sized three-phase motors across numerous industries. In General Manufacturing, it is used for machine tools, conveyor belts, fans, and small compressors. Building Automation applications include control of HVAC fans, pumps, and air handling units. The Water and Wastewater sector utilizes it for small chemical dosing pumps and aerators. It is also found in Agriculture for irrigation pumps and in Commercial Facilities for various motor-driven equipment. Any application requiring reliable, standalone protection and control for a motor up to approximately 11 kW (at 400V) is a suitable candidate for this compact motor starter.
Related Products
The 2MLR-AC22 is part of a system for motor control. Related products and accessories include:
- Honeywell Contactors: Higher-capacity or electrically held contactors (like the 2MLR series contactors) for remote/automated control when used in conjunction with a separate thermal overload relay.
- Auxiliary Contact Blocks: Add-on contact blocks (NO/NC) to provide signaling contacts for control circuits or PLC inputs to indicate the starter’s status.
- DIN-Rail Mounted Circuit Breakers or Fuses: Upstream devices required to provide short-circuit protection for the motor branch circuit, as the manual motor starter typically provides overload protection only.
- Motor Protection Circuit Breakers (MPCBs): Alternative devices that combine short-circuit and overload protection in one unit, such as other Honeywell or third-party brands.
- Control Transformers: To provide the appropriate control voltage (e.g., 24V AC) for the coil if the starter is used in a contactor configuration.
- Push Buttons and Selector Switches: For creating local control stations to operate the starter remotely.
- Horsepower Rated Motor Disconnects: Alternative manual disconnecting switches for motor circuits.
