Overview
The Challenger CFS 14k is a molded case circuit breaker engineered for reliable overcurrent protection in commercial and industrial electrical distribution systems. This plug-on style breaker features a compact design and delivers a 14,000 ampere interrupting capacity (AIC) at rated voltage, making it suitable for applications requiring robust short-circuit protection without taking up excessive panel space.
Key Features
- 14,000 AIC rating provides high-performance short-circuit protection
- Plug-on mounting style for quick installation and replacement
- Thermal-magnetic trip mechanism for reliable overload and fault detection
- Compact molded case design fits standard breaker panels
- Designed for commercial and industrial power distribution applications
Technical Specifications
The Challenger CFS 14k delivers standard specifications for mid-range molded case breakers. Voltage ratings typically range from 240V to 480V AC, with amperage options available across common values. The 14k AIC interrupting capacity at 480V makes this breaker suitable for facilities requiring enhanced short-circuit protection. Thermal-magnetic trip units provide dual protection against overloads and instantaneous faults. The plug-on mounting design allows for tool-free installation in compatible breaker enclosures.
Typical Applications
- Commercial HVAC and refrigeration systems
- Industrial motor feeders and distribution panels
- Facility power distribution and feeder circuits
- General purpose branch circuit protection
- Equipment retrofits and panel upgrades
