Typical Applications
The 505X-TOD /D suits applications requiring reversible motor control in compact spaces, including:
- Conveyor systems with reversing capability
- Pump and fan motor control
- Machine tool control circuits
- HVAC equipment operation
- Industrial process machinery requiring directional control
Compatibility & Replacements
The Allen-Bradley 505X-TOD /D is part of the Bulletin 505 motor control family and is designed for use with standard Bulletin 505 motor control systems. This open-type starter requires a separate branch circuit disconnect switch or circuit protection device, as it provides no integral disconnection means. When replacing an existing 505-series starter, verify matching coil voltage, contact amperage rating, and load voltage specifications. Compatible repair parts and overload relay elements are available through Allen-Bradley distributors.
