Q1B215 - 15 Amp Circuit Breaker

Q1B215 - 15 Amp Circuit Breaker

Safeguard your electrical system with the Q1B215 15A circuit breaker, purpose-built for dependable service in both commercial and residential applications. Whether you're updating existing infrastructure or reinforcing circuit protection, this 2-pole, 15-amp breaker provides consistent defense against overloads and short circuits. Its combination of thermal and magnetic trip elements helps ensure fast response to fault conditions while maintaining stability under normal loads.

Key Features and Benefits

• Thermal-magnetic trip action: Protects against sustained overloads (thermal) and sudden surges or short circuits (magnetic), giving you dual-mode safety.
• Space-efficient footprint: Requires only four panel spaces, making it ideal for retrofits or tight installations where space is at a premium.
• Bolt-on mounting: Delivers a solid, vibration-resistant connection that resists loosening over time, even under heavy usage.
• Built for long life: Constructed from high-grade materials and designed for repeated cycling in demanding environments, delivering years of reliable performance.
• Trip-free mechanism: Cannot be held closed manually in an overcurrent state, ensuring that safety is never bypassed.

Material Compliance and Certifications

• This breaker is manufactured to meet UL standards for molded-case overcurrent devices, including UL 489 listing for circuit breakers used in branch circuit protection. (UL standards define rigorous testing protocols for overload, short circuit, dielectric strength, and endurance.)
• All components are fabricated from durable, flame-retardant materials and assembled under quality controls aligned with industry best practices. The design ensures consistent performance under real-world conditions and is ready for approval under standard safety codes.

Where It Works Best

• If you're working on a maintenance project or upgrading legacy electrical panels, the Q1B215 fits smoothly into existing systems without major rewiring. It’s well suited for branch circuit protection in small commercial spaces, light industrial installations, or residential settings where dependable fault protection is critical. Because of its compact size and straightforward bolt-on design, it’s especially useful when space is limited or when you’re replacing older breakers. Use it wherever you need reliable, code-compliant overcurrent protection that won’t require drastic modifications to your current setup.
