Overview
The Allen-Bradley 1489-M2D030 /D is a thermal-magnetic miniature circuit breaker designed for branch circuit protection in industrial control systems. This 3-amp, 2-pole device operates at 480Y/277V AC and 96V DC with a Type D trip curve, making it suitable for inductive loads and motor circuits requiring coordinated overcurrent protection.
Key Features
- Interrupt Rating: 15 kAIC for reliable short-circuit protection
- Current-Limiting Design: Reversible line and load connections with dual terminals for wiring and bus bar flexibility
- Multi-Standard Certification: UL, CSA, CUL, CE, and CCC approved
- D-Curve Characteristic: Optimized for circuits with inrush current demands typical of control circuits and solenoids
- Compact Form Factor: Fits standard DIN rail mounting in industrial enclosures
Technical Specifications
The 1489-M2D030 /D delivers precise overcurrent protection with thermal-magnetic trip elements designed to respond quickly to short circuits while tolerating brief inrush transients.
Typical Applications
- Industrial control panel branch circuit protection
- Motor starter and solenoid coil circuits
- Automation equipment and machinery protection
- Process control systems requiring coordinated overcurrent detection
- Electrical distribution in manufacturing facilities
Compatibility & Replacements
The 1489-M2D030 /D is part of the Bulletin 1489-M thermal magnetic circuit breaker family, approved for both North American and IEC applications. Bulletin 1489-M breakers are certified as Miniature Circuit Breakers for IEC applications and approved for branch circuit protection in the United States and Canada. Verify voltage and pole configuration when ordering replacements or spares to ensure panel compatibility.
