Information About FY14015C
The FY14015C is part of Square D’s I-Line FY series of molded case circuit breakers (MCCBs), engineered for reliable branch protection in commercial and industrial power distribution systems. This breaker is rated for 15 amps, features a 1-pole thermal-magnetic trip mechanism, and operates at up to 277 VAC, making it ideal for lighting panels and other single-phase applications. Its I-Line plug-in construction ensures secure, tool-free mounting within I-Line panelboards, supporting faster installation and maintenance. The unit offers an interrupt rating of 14 kA at 277 VAC, suitable for medium-duty fault current environments, and is built within the robust F-frame housing format.
Key Features:
- 15 Amp Protection: Provides standard branch circuit protection for single-phase 277 V AC loads.
- Thermal-Magnetic Trip Unit: Utilizes a long-time (thermal) and instantaneous (magnetic) trip mechanism for overload and short-circuit protection.
- I-Line Plug-In Mounting: Fast and secure connection to I-Line panelboards via plug-on line terminals, reducing wiring labor and enhancing safety.
- Single-Pole Configuration: Optimized for circuits that require only one current path—ideal for lighting or branch load protection.
- 277 VAC Operation: Supports commercial lighting and equipment loads in single-phase 277V distribution systems.
- High Interrupting Capacity: Rated at 14,000 AIC @ 277V AC, enabling safe interruption of moderate fault currents.
- AL50FA Terminal Lugs: Rugged load-side lug configuration allows connection of aluminum or copper conductors.
- Compact F-Frame Size: Slim 1.5" width and 4.13" height for space-saving installations; total length is 6.4".
- UL and CSA Certified: Complies with North American electrical safety and installation standards.
The FY14015C simplifies integration into legacy I-Line panels with its compact F-frame format and plug-in mounting. Its solid interrupting capacity and thermal-magnetic protection make it a dependable choice for branch circuit protection in commercial and industrial settings where 277V single-phase systems are in use.
