Overview
The Allen-Bradley 1489-M2C030 is a thermal-magnetic miniature circuit breaker designed for reliable branch circuit protection in industrial and commercial control panels. Part of the Bulletin 1489-M series, this 2-pole, 3-ampere breaker carries UL489 certification for North American applications and IEC compliance for international deployments. The Type C trip curve provides fast response to moderate overloads while rejecting nuisance trips from inrush currents, making it ideal for motor branch circuits and general-purpose loads.
Key Features
- Type C Trip Curve: Optimized for motor circuits and inductive loads with moderate inrush tolerance
- Dual Terminal Design: Supports both wire termination and UL 508 Listed bus bar connection for panel flexibility
- UL/CSA & IEC Certification: Approved for branch circuit protection in the United States, Canada, and international markets
- Compact Footprint: Standard miniature form factor for space-efficient DIN rail mounting in control enclosures
- Accessory Support: Compatible with auxiliary contacts, signal contacts, shunt trips, and lockout attachments
