509-AOD - Allen Bradley Magnetic Starter Description
509-AOD - Allen Bradley Magnetic Starter
The Allen-Bradley 509-AOD is a compact, full-voltage (Direct-On-Line) non-reversing motor starter designed to meet NEMA Size 0 standards. Engineered for reliable three-phase squirrel-cage motor control, it delivers 18 A continuous current at up to 600 VAC and includes a rugged eutectic alloy thermal overload relay. This open-frame starter is ideal for industrial control panels, MCCs, and OEM machines requiring space-efficient, dependable single-direction motor control.
Key Features and Benefits
- Standard Coil Voltage: Operates on 110–120 VAC at 50/60 Hz for common control circuits
- 18 A Continuous Rating: Suitable for motors up to 2 HP at 380–575 VAC
- High Starting Power: Peak inrush current supports up to 5 HP at 575 VAC (~5.2 kVA)
- Thermal Overload Relay: Temperature-compensated eutectic alloy relay with manual reset for consistent protection
- Space-Saving Build: Compact NEMA Size 0 open-frame design enables tight panel integration
