Q1B315 - 15 Amp Circuit Breaker

Q1B315 - 15 Amp Circuit Breaker

Upgrade and safeguard your electrical system with the Q1B315 15A Bolt-On Thermal Magnetic Circuit Breaker—a dependable, compact solution built for commercial and industrial use. Designed for those who need a drop-in replacement or maintenance part, this breaker delivers reliable protection against overloads and short circuits while maintaining the integrity of existing panel layouts.

Key Features and Benefits

• Thermal + Magnetic Protection: Combines overload (thermal) and short circuit (magnetic) response in one unit, shielding your wiring and connected equipment from damage.
• Bolt-On Design: Installs securely using bolt mounting, minimizing issues with loose wiring and ensuring a firm connection—even in high-vibration environments.
• Slim Profile (6 Spaces): Despite being a 3-pole breaker, it fits into just six spaces, letting you maintain your current panel configuration without rework.
• 10 kA Interrupting Capacity @ 240 VAC: Designed to handle high fault levels, giving you peace of mind in demanding installations.
• Consistent Performance: Engineered to deliver predictable trip characteristics over time, helping you avoid nuisance trips or under-protection.
