General Electrics TEYL1045B - 45 A, 1-Pole Bolt-On Circuit Breaker | AmpState

The General Electric TEYL1045B is a 45A, 1-pole bolt-on molded case circuit breaker purpose-built for dependable branch-circuit overcurrent and short-circuit protection in panelboards and loadcenters. With its rugged bolt-on mounting and thermal-magnetic trip technology, this breaker delivers reliable protection where it matters most—in homes, offices, and light industrial spaces.

Why this breaker stands out

• Secure bolt-on mounting ensures a rigid, vibration-resistant connection to the bus, reducing the risk of loose connections and ensuring consistent performance in environments with movement or vibration.
• Thermal-magnetic trip unit provides stable, repeatable protection against overcurrent and short circuits, adapting to changing load conditions without false trips.
• OEM compatibility designed to be compatible with matching General Electric OEM loadcenters and panelboards, simplifying installation and ensuring proper coordination with your system.
• Versatile application suitable for residential, commercial, and light industrial settings, making it a flexible choice for a range of electrical protections.

How it works in real-world scenarios

• Upgrading a panelboard to enhance protection for critical lighting and receptacle circuits in a retrofit project.
• Replacing a worn breaker in a GE-compatible loadcenter to restore precise overcurrent and short-circuit protection without altering the panel’s footprint.
• Installing in environments where vibration or equipment motion is present (e.g., mechanical rooms or multi-story installations) to maintain a solid electrical connection.
