Overview
The Allen-Bradley 1489-A1C015 is a compact, single-pole miniature circuit breaker in the Series A line. Rated at 1.5 amps with 277VAC / 48VDC dual voltage capability, this breaker provides dependable protection against overloads and short circuits in industrial machinery, control systems, and lighting applications. Its DIN rail mounting and Type C thermal-magnetic trip characteristic make it suitable for a wide range of electrical protection scenarios.
Key Features
- Type C magnetic trip characteristic (activates at 5–10 times rated current)
- Single-pole configuration for compact protection
- Dual voltage operation: 277VAC / 48VDC
- DIN rail mount for space-efficient panel installation
- UL 489 certified for North American standards compliance
- Series A design with proven thermal-magnetic performance
Technical Specifications
The breaker operates at 50/60 Hz and uses thermal detection at a 40°C reference temperature. Its Type C trip curve ensures fast response to fault currents while avoiding nuisance trips on normal inrush. Line and load terminals may be reversed for flexible installation.
Typical Applications
- Industrial motor and machinery control circuits
- Lighting and heater load protection
