Overview
The Allen-Bradley 509-BOD is a three-phase, non-reversing full-voltage motor starter designed for reliable motor control in industrial automation systems. This NEMA Size 1 starter combines a robust contactor assembly with an integrated eutectic alloy overload relay, providing comprehensive motor protection and control in a compact footprint suitable for panel mounting and bulletin 500 motor control centers (MCCs).
Key Features
- Eutectic alloy overload relay with integrated test module for predictable thermal protection
- Full-voltage NEMA control suitable for three-phase or single-phase motors
- Heavy-duty 600VAC rated contacts capable of 7200VA make and 720VA break ratings
- Coil voltage options: 115-120VAC @ 60Hz or 110VAC @ 50Hz
- Mounted contacts and open-type construction without enclosure for flexible installation
- Auxiliary contact blocks available for alarm and status signaling

Compatibility & Replacements
The 509-BOD Series B is compatible with Allen-Bradley Bulletin 509 mechanical starters and can accept auxiliary contact blocks (part numbers 595-A02, 595-AB) for alarm and interlock functions. The 42185-800-01 eutectic alloy overload relay assembly is a direct replacement component. When sourcing used or remanufactured units, verify Series letter (B in this case) and coil voltage to ensure proper control circuit compatibility. Common equivalent starters in the Bulletin 509 family include Size 0, 2, 3, 4, and 5 variants with similar contactor configurations but different current ratings.
