Product Advantages

• Robust and Reliable: Built by Allen-Bradley (Rockwell Automation), a leader in industrial automation, ensuring high quality and durability.
• Versatile Mounting: Designed for easy front/door mounting, offering flexibility in panel design.
• Safety Features: Features IP20 finger-safe terminals to enhance safety during installation and operation.
• High Load Capacity: Capable of handling significant loads, suitable for motor control and general load switching.
• Durability: High mechanical life ensures long-term performance and reduced maintenance.
• Customizable: The separate actuator selection allows for tailored solutions based on specific application requirements (e.g., color, padlockability).

Precautions

• Actuator Required: Remember that the 194L-E25-1752 is an open switch and requires a separate actuator (handle) for operation. Ensure the correct actuator is chosen and properly installed.
• Enclosure Protection: While the front side can achieve IP66 with the right handle, the switch body itself is IP20. It must be installed within an appropriate enclosure to protect it from environmental factors like dust and moisture if an IP rating higher than IP20 is required for the entire assembly.
• Electrical Safety: Always adhere to proper electrical safety procedures during installation, wiring, and maintenance. Disconnect power before working on the switch.
• Correct Wiring: Ensure correct wiring practices according to local electrical codes and the product’s documentation to prevent damage and ensure safe operation.
• Load Compatibility: Verify that the load being switched is within the specified current and power ratings of the device.

Product Applications

The Allen-Bradley 194L-E25-1752 load switch is typically used in various industrial applications where manual switching of power to machinery or circuits is required. Common applications include:

• Motor Disconnect: Suitable as an “at-motor disconnect” for small to medium-sized motors, providing a local means to cut power for maintenance or emergency stops.
• Main Circuit Breaker / Isolator: Used as a main switch for small panels or individual machine circuits to isolate power.
• Control Panel Power Disconnect: Providing a clear ON/OFF control for specific sections of a control panel.
• Lighting Circuits: Switching power for industrial lighting systems.
• Heating Elements: Controlling power to resistive heating elements.
• HVAC Systems: Used in the control circuits of heating, ventilation, and air conditioning systems.
