The Intermatic K4233 277 Volt Knuckle Cell is a reliable and durable electrical time switch designed for commercial and industrial applications. This time switch is designed to automate the operation of electrical loads, such as lighting, fans, and HVAC systems, based on a pre-set time schedule.
The K4233 is a 2-pole, 3-way time switch, which means it can control two separate loads and can be used in a 3-way circuit. It is rated for 277 volts, making it suitable for use in commercial and industrial environments where higher voltage power sources are common.
The switch features a rugged, all-metal construction, with a powder-coated finish that is resistant to corrosion and weathering. It also has a large, easy-to-read dial that allows for simple and accurate time setting. The dial is illuminated with a high-intensity LED for easy reading in low light conditions.
The K4233 also includes a built-in mechanical override switch, which allows for manual control of the electrical load outside of its pre-set time schedule. This feature is particularly useful in situations where unexpected events require the need to override the automation.
In addition, the switch is equipped with a removable terminal block, which makes it easy to install and connect wires. It also features a locking mechanism to prevent accidental adjustments to the time setting.
Overall, the Intermatic K4233 277 Volt Knuckle Cell is a high-quality, reliable, and easy-to-use time switch that is ideal for commercial and industrial applications where automation and energy savings are important. Its rugged construction, large and easy-to-read dial, built-in override switch, and removable terminal block make it a versatile and convenient solution for controlling electrical loads.
