Overview
The Allen-Bradley 140-MN-0160 is a robust manual motor starter protector designed for reliable thermal and magnetic protection of general-purpose motors in industrial automation systems. Operating at 1.0–1.6 amps with trip current set at 120% FLA (Full Load Amps), this three-pole device provides instantaneous magnetic trip protection at 18 amps, ensuring rapid disconnection under fault conditions.
Key Features
- Thermal and Magnetic Protection: Combines thermal overload with instantaneous magnetic tripping to protect motors from overload and short-circuit conditions.
- 3-Pole Configuration: Suitable for three-phase motor control applications.
- Trip Current 120% FLA: Standardized trip setting minimizes nuisance tripping while maintaining motor protection.
- Manual Reset: Operator-controlled reset after overload event for quick recovery and diagnostics.
- DIN Rail Mounting: Space-efficient installation in control panels and motor control centers.
- Screw Terminal Connections: Standard 6 screw terminals (16–10 AWG) for reliable field wiring.
