Why this GE breaker stands out

Designed for reliability in industrial and commercial power distribution, the TLB234150WL delivers robust short-circuit protection with a 50 kA interrupt rating, reducing the risk of cascading faults in high-demand 480V systems. The feed-through design adds value by enabling downstream feeders to be protected and wired efficiently, which can simplify upgrades, retrofits, and maintenance projects.

Who should consider the TLB234150WL

• Facilities upgrading 480V distribution networks that require dependable, high-current protection.
• Manufacturing floors and data centers looking to streamline feed-through wiring and downstream protection.
• Maintenance teams performing retrofit or replacement of aging panels with compatible, GE-branded components.

Practical use cases

• Retrofit an existing 3-phase, 480V panel to add protected downstream circuits without adding extra enclosures.
• Replace a worn or obsolete GE breaker with a like-for-like part to minimize downtime and ensure consistent performance.
• Install in new or upgraded switchgear where a high interrupt rating and precise current handling are essential for safety and reliability.

How this compares to alternatives

Unlike standard single-section breakers, the TLB234150WL’s 3-pole configuration guarantees simultaneous disconnection across all phases, which is critical for balanced power distribution and preventing arc-related faults. The feed-through capability reduces wiring complexity and enables efficient protection of downstream circuits, a clear advantage in space-constrained panels and retrofit projects.

Compatibility and setup tips

• Always verify fit and ratings against your existing gear before ordering—matching the catalog number TLB234150WL is the best reference for compatibility.
• Ensure your panel or switchgear supports a 3-pole, 480V feed-through protective device of this type.
• During installation, follow standard torque specs for lug connections and check that downstream breakers or feeders are properly terminated.

Maintenance and care

Periodically inspect for signs of wear, overheating, or corrosion at lugs and conductors. Keep connections clean and tight, and replace any damaged components promptly to maintain the breaker's 50 kA interrupt capability and reliable performance in demanding environments.
