NGB3B015B - 15 Amp Circuit Breaker

NGB3B015B - 15 Amp Circuit Breaker

When you're replacing a breaker in an existing panelboard, the small details matter. The NGB3B015B is a 15-amp, 3-pole Type NGB molded-case circuit breaker designed for compatible panelboard-mounted applications. It has an interrupting rating of 25kA at 480VAC and 100kA at 240VAC, a 40.25°C temperature rating, and an HACR rating. The breaker measures 5.0 inches high, 3.0 inches wide, and 3.06 inches deep, and it includes load-side terminals. Check those specifications carefully when matching a breaker already installed in older or legacy electrical equipment. Rather than choosing based on appearance alone, compare the part number, dimensions, amperage, poles, mounting style, voltage, and A.I.C. rating with your panelboard requirements. For systems specifically designed around the NGB3B015B configuration, this breaker provides the form, fit, and function needed to keep existing equipment in service. Simply put, it's a straightforward electrical component built to last and designed to do the job it was made for when properly installed and used within its ratings.

Key Features and Benefits

• 15 amp rating for applications requiring this specific current rating.
• 3-pole design for compatible three-pole circuits.

Material Compliance and Certifications

• The NGB3B015B is HACR rated and has a stated temperature rating of 40.25 °C. The supplied specifications identify no other material-compliance certifications, so don't assume additional certifications.
• If your installation has specific code, certification, or material requirements, check the markings and documentation on the breaker and verify them against the equipment and application requirements.
  

Where It Works Best

• The NGB3B015B makes the most sense in existing panelboards and legacy electrical systems that call for a compatible Type NGB molded case circuit breaker. This is especially useful in maintenance situations where the goal is to preserve the original system configuration rather than change it.
