Key specifications at a glance

• Amperage: 40A
• Poles: 3‑Pole
• Voltage rating: 480V
• Part number: TLB134040WL

Why this 40A, 3‑Pole GE breaker stands out

• Precisely matched for 3‑phase, 480V electrical systems, delivering reliable protection where it’s most crucial—industrial equipment, motor drives, and commercial facilities with heavy loads.
• Designed for retrofit and replacement projects, eliminating guesswork when you're upgrading an aging panel or panelboard that requires the exact GE specification.
• The TLB134040WL designation is your quickest path to compatibility, minimizing downtime and ensuring a seamless fit with GE panels and other systems that accept the same 3‑pole, 480V format.

Ideal use cases

• Replacing a failed 3‑pole 480V breaker in a manufacturing line or processing equipment circuit.
• Retrofit projects where upgrading to a GE unit with the exact part reference ensures consistent protection and predictable performance.
• Maintenance cycles in data centers, cooling systems, or industrial controls that run on 480V three‑phase power.

What to consider before ordering

• Confirm fit and ratings before ordering to avoid compatibility issues with panel models and bus configurations.
• Use the part number TLB134040WL as the primary reference when matching replacement units to your existing installation.
• Ensure your system operates on a 480V three‑phase supply and that a 40A protection point aligns with the connected load.

Practical guidance and insights

When selecting a replacement, prioritize exact spec parity over generic “one-size-fits-all” options. A breaker that matches the amperage, pole count, and voltage prevents nuisance trips and ensures predictable coordination with downstream protection devices. For extended service life, keep the panel environment clean and dry, and verify that the wiring gauge and torque specifications align with your installation guidelines.
