Eaton NSB CHFGFT115 Miniature Circuit Breaker

The Eaton NSB CHFGFT115 Miniature Circuit Breaker is a 1P, 15A MCB. It is part of Eaton's NSB family and is identified by the CHFGFT115 model code, designating a single-pole, 15-amp protective device used to guard electrical circuits against overcurrent. In normal operation, the breaker allows current to flow through the protected conductor until the load or fault current reaches the 15-amp rating, at which point the device trips to interrupt the circuit. This rapid disconnection helps prevent overheating, insulating damage, and potential fire hazards associated with sustained overcurrent conditions. The single-pole form factor makes it suitable for protecting a single live conductor branch and simplifies replacement in compatible panel installations. Use of 1P 15A MCBs like CHFGFT115 is common in electrical distribution schemes where individual circuit protection is required without a multi-pole interlock.
