Square D 9007C54A Limit Switch Spdt Nc Roller Lever 600V

Product Description

The SQUARE D 9007C54A is a general purpose limit switch designed for industrial and commercial control applications where precise position detection is required. It features a single-pole double-throw (SPDT) contact form with a normally closed (NC) configuration and a roller lever actuator mounted at the top of the housing. Rated for up to 600 volts, the 9007C54A is built with a zinc alloy body for durability in demanding environments. Screw terminals provide a secure, reliable wiring connection. Licensed electricians and industrial control technicians are the primary installers of this device.

The 9007C54A suits industrial machinery, conveyor systems, automated equipment, and process control panels where limit or position sensing is needed. Its roller lever actuator responds to mechanical contact from moving components, making it well suited to door interlock systems, end-of-travel detection, and safety shutoff circuits. The operating temperature range of -20 degrees F to 185 degrees F allows installation in both cold-storage and warm industrial environments. It is appropriate for both new installations and direct replacement of worn or failed limit switches in existing control systems.

Key Features

• SPDT contact form with normally closed (NC) configuration for fail-safe circuit design
• Roller lever actuator positioned at the top for straightforward mechanical engagement
• 600-volt rating supports a wide range of industrial control voltages
• Zinc alloy body provides corrosion resistance and mechanical durability
• Screw terminal connections for secure, tool-accessible field wiring
• CE, CSA Certified, and UL Listed for compliance with major North American and international standards

Compatibility

Designed as an OEM-style replacement or new-installation general purpose limit switch for industrial and commercial control systems requiring a top-mounted roller lever actuator with SPDT NC contacts at up to 600 volts.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the circuit before wiring or replacing the switch. Verify that the mechanical actuator alignment allows full roller lever travel without binding, and confirm that the mounting surface is rigid enough to prevent misalignment under repeated actuation cycles.
