Overview
The Allen-Bradley 1492-SP1C160 is a miniature molded case circuit breaker designed for supplementary protection in industrial and commercial electrical systems. Rated for 16 amps at a maximum of 277 volts AC for US applications, or 240 volts AC for IEC settings, this breaker provides reliable overcurrent protection with thermal-magnetic operation.
Key Features
- C-trip characteristics with long-time and instantaneous trip functions
- C-curve operation ideal for environments with high inrush currents, such as motor starters and lighting circuits
- 10kA interrupt capacity at 277V
- Single-pole with feed-through design and line & load lug terminals
- No programming required—simple plug-and-protect operation
- Compact design for integration into standard panelboards
