1494C-CM11 Allen‑Bradley cable

Product Detailed Description

The Allen-Bradley 1494C-CM11 is a cable-operated mechanism designed for use with the 1494C series of visible blade disconnect switches from Rockwell Automation. It enables remote operation of the disconnect switch via a flexible cable, allowing the handle to be mounted externally on the enclosure door while the switch body remains inside the panel. This mechanism provides reliable disconnection for electrical circuits in industrial control panels, ensuring safe isolation of power sources. It is part of the Bulletin 1494C family, which emphasizes visible blade technology for clear ON/OFF indication, enhancing operator safety during maintenance or troubleshooting.

Product Parameters

Product Advantages

• Flexible Installation: The 6 ft cable allows mounting the operating handle in convenient locations, such as enclosure doors, without requiring rigid shaft extensions, ideal for deep or complex panel designs.
• Enhanced Safety: Supports visible blade disconnect switches, providing clear visual confirmation of the disconnection state to prevent accidental energization.
• Durability and Reliability: Robust construction withstands industrial environments, with a high operational life cycle, reducing maintenance needs and downtime.
• Compliance and Versatility: Meets multiple international standards (UL, cUL, etc.), making it suitable for global applications, and integrates seamlessly with Allen-Bradley ecosystem for scalable control systems.
• Cost-Effective Remote Operation: Enables remote actuation without additional complex linkages, simplifying retrofits in existing panels.

Precautions and Notes

• Installation: Ensure proper cable tension and alignment during setup to avoid binding or excessive wear; consult the 1494C series installation manual (publication 1494-IN010) for torque specifications and mounting procedures. The mechanism must be used only with compatible 400 A rated switches.
• Safety: Disconnect power before installation or maintenance. The cable mechanism does not provide arc flash protection; use appropriate PPE and follow lockout/tagout (LOTO) procedures.
• Environmental Limits: Rated for indoor use in pollution degree 2 environments (non-conductive pollution); avoid exposure to corrosive atmospheres, excessive vibration, or temperatures outside -10°C to +40°C (14°F to 104°F).
• Availability: Subject to long lead times; verify stock with authorized distributors. Not intended for direct load switching—use as a disconnect only.
• Warranty and Service: 18-month standard warranty from Rockwell Automation; for repairs, contact authorized service centers to avoid voiding coverage.

Product Applications

The 1494C-CM11 is widely used in industrial automation and control systems where safe, remote power disconnection is essential. Key applications include:

• Motor Control Centers (MCCs): For isolating drives and motors in manufacturing plants.
• Electrical Distribution Panels: In commercial buildings, data centers, and utilities for maintenance access.
• HVAC and Process Equipment: Enabling safe shutdown in heating, ventilation, and industrial processing setups.
• Renewable Energy Systems: Disconnecting inverters or transformers in solar/wind installations.
• OEM Machinery: Integrated into custom machines requiring compliant, visible disconnection for CE/UL certification.
