Overview
The Allen-Bradley 1492-SP3C080 is a 3-pole supplementary protector miniature circuit breaker designed for reliable overcurrent protection in industrial control systems. Part of the proven 1492-SP product line, this unit features Type C trip characteristics and an 8-amp rated current, making it ideal for equipment protection, control circuits, and panel-mounted applications requiring fast breaking time and current-limiting performance.
Key Features
- Current-limiting technology — rapid arc suppression reduces energy let-through during faults
- Type C trip curve — magnetic trip activated at 5–10 times the rated current
- Dual terminals — accept both wire and bus bar connections for flexible panel layout
- Screw termination — accepts #16–4 AWG (1.5–25 mm²) copper wire on both line and load sides
- 3-pole handle-connected design — simultaneous operation across all three poles
- 40°C calibration temperature — eliminates need to derate for 508A industrial control panel installations
