NB232015 - 15Amp Circuit Breaker

NB232015 - 15Amp Circuit Breaker

The NB232015 15 amp circuit breaker is a three-pole, bolt-on thermal magnetic breaker engineered to deliver dependable protection in 240VAC electrical distribution systems. Designed for residential and light commercial applications, this 15A three-pole circuit breaker helps safeguard wiring and connected equipment from overloads and short circuits. With a 10kA AIC rating at 240VAC, it provides the interrupting capacity required for many branch circuit applications, while the bolt-on mounting style ensures a tight, secure fit within compatible panelboards. Built with durability and performance in mind, the NB232015 is a reliable choice for maintaining the safety and stability of your electrical system.

Key Features and Benefits

• Three-Pole Protection: Provides coordinated protection across all three phases of a 240VAC circuit, making it suitable for three-phase loads and equipment requiring balanced coverage.
• 15 Amp Rating: Rated at 15 amps, this breaker is ideal for branch circuits that require precise overcurrent protection without oversizing.
• Thermal Magnetic Trip Mechanism: Combines a thermal element for overload protection and a magnetic element for short-circuit response, helping prevent damage to conductors and connected equipment.
• 10kA Interrupting Capacity at 240VAC: With a 10,000 AIC rating, the NB232015 is built to safely interrupt fault currents within its specified rating.
• Bolt-On Mounting Design: The bolt-on configuration creates a secure mechanical and electrical connection to the panelboard bus, helping reduce the risk of loose connections and improving long-term reliability.
• Compact, Panel-Ready Construction: Engineered to fit efficiently within compatible electrical panels, offering strong performance without sacrificing valuable panel space.
