Overview
The Allen-Bradley 1489-M2C160 is a thermal-magnetic miniature circuit breaker designed for branch circuit protection in industrial control and power distribution systems. As part of the Bulletin 1489-M family, this breaker combines reliable trip performance with compact DIN-rail mounting for space-constrained panel installations. It meets UL489 and CSA requirements, making it suitable for both North American and international IEC/EN applications.
Key Features
- Thermal-Magnetic Protection: Precise temperature and magnetic trip elements ensure fast, reliable fault clearing
- Type C Trip Curve: Optimized for general-purpose branch circuits with moderate inrush currents
- Standard Configuration AC: Rated for alternating current applications up to 480Y/277V
- DIN-Rail Mounting: Space-efficient installation on standard 35mm DIN rail
- Fast Breaking Action: Superior shock and vibration resistance in extreme ambient conditions
- Dual Certification: UL489, CSA, CUL, and CCC approvals for broad global deployment
Technical Specifications
The 1489-M2C160 delivers 16-amp rated current with a 15-kAIC interrupt rating at 480V, providing robust protection for typical industrial branch circuits. Its 2-pole configuration supports three-phase and split-phase circuit protection.
Typical Applications
- Industrial control panel branch circuit protection
- Motor starter and VFD input protection
- Lighting and receptacle circuit distribution
- HVAC and process equipment branch circuits
- Machinery and automation system power distribution
Compatibility & Replacements
The 1489-M2C160 is part of the Allen-Bradley Bulletin 1489-M miniature breaker series, which integrates with standard industrial control panel designs. The /D series designation indicates the current product revision. This breaker is compatible with any DIN-rail mounting system supporting standard 35mm rail spacing. For applications requiring alternative trip curves, amperage ratings, or pole configurations, consult the full Bulletin 1489-M product line. Always verify voltage and interrupt rating compatibility before substitution.
