KB Electronics 8811007 Solid State Variable Speed AC Motor Control — 6.0A, 115V (K177-1006)

Overview

The KB Electronics 8811007 solid state variable speed control delivers smooth, precise ramping for shaded pole and PSC motors. With a maximum rating of 6.0 amps at 115 volts, this device is designed to adjust airflow and fan performance across a range of everyday applications. The solid state design provides reliable speed changes without the need for mechanical gears, and it carries UL and CSA approvals for safety and reliability.

Key benefits

• Infinite speed adjustment enables fine tuning of motor output to suit different environments and tasks.
• UL and CSA approved construction supports safety and durability in residential and light commercial settings.
• Compact form fits standard 2" x 4" electrical boxes for straightforward installation.
• Clear amperage rating helps prevent overloading the control or connected motor, supporting safer operation.

In real world use, you may experience smoother start ups and gradual speed changes that can reduce noise and vibration. This control is compatible with a variety of devices such as fans, blowers, fireplace blowers, attic fans, humidifiers, and ventilators, making it a versatile option for upgrading existing cooling, ventilation, or climate-related equipment.

Applications and use cases

• Fans and blowers in homes or light commercial environments needing adjustable airflow.
• Attic fans and ventilation devices where controlled air movement is desirable.
• Humidifiers and ventilators that benefit from steady, adjustable speed control.
• Direct drive configurations that require cooling via a fan blade on the shaft.

Important usage notes are highlighted to help you plan installations wisely. The control is rated for 6.0 amps at 115V and should not be used with capacitor start or capacitor run motors. Do not exceed the motor name plate amperage, as overloading the control or motor can lead to overheating. The motor should have adequate torque to prevent stalling, and when used in direct drive systems, a fan blade must be installed on the shaft to provide cooling. While these guidelines support reliable operation, they do not replace the need for proper electrical work and routing of components in accordance with local codes.

Installation and safety considerations

• Designed for a standard 2 inch by 4 inch electrical wall box for easy mounting.
• UL and CSA approvals indicate compliance with safety standards for electrical components.
• Note that mounted controls are not returnable, so verify fit and compatibility before final installation.
