General Electric | TLB134090 | Circuit Breaker | 90A | 3-Pole | 480V

Meet the General Electric TLB134090, a purpose-built circuit breaker engineered to protect 3-phase electrical systems at higher voltages. With a 90-amp rating and a 3-pole configuration, this GE breaker is designed for demanding industrial applications where reliable, fast-disconnect protection is essential for equipment longevity and personnel safety.

Key specifications at a glance

• Amperage: 90A
• Poles: 3-Pole
• Voltage: 480V
• Model reference: TLB134090

Why this 90A, 3-Pole, 480V GE breaker stands out

This circuit breaker is purpose-built for three-phase power distribution common in manufacturing, processing, and large commercial facilities. The 90A rating provides robust protection for motors, drives, and other heavy-load equipment while allowing clean, predictable tripping behavior when fault conditions arise. The 3-pole design ensures simultaneous interruption of all three hot legs, preventing dangerous arcing scenarios and safeguarding connected equipment from uneven phase faults.

Ideal use cases

• Maintenance, retrofit, or replacement projects in existing 3-phase 480V electrical systems
• Industrial panels and switchgear where consistent 90A protection is required
• Equipment rooms, manufacturing lines, and automation closets that rely on reliable, fast fault-clearing performance

Practical considerations for buyers

Before ordering, confirm that this exact part number (TLB134090) matches your panel or distribution equipment. The part number is the most reliable reference for compatibility, especially in installations where specific trip curves, mounting, and terminal configurations matter. If you’re replacing an existing GE breaker or upgrading to 480V three-phase protection, this model aligns with standard GE configurations used in many industrial environments.

How it helps your operation

• Protects motor starters, contactors, and drives from overload and short-circuit conditions
• Minimizes downtime with predictable, quick isolation of faults
• Improves safety by ensuring all three lines are interrupted together during a fault

Installation and compatibility tips

Plan your replacement by verifying panel catalog references and ensuring mounting and terminal arrangements match the TLB134090 specification. For retrofit projects, align the new breaker with existing wire sizing, conductor insulation ratings, and enclosure space to maintain compliant and orderly protection.

Choosing the General Electric TLB134090 means selecting a proven, purpose-built solution for 90A, 480V three-phase protection. It’s a dependable choice for maintenance teams, facilities managers, and engineers who value precise compatibility, straightforward replacement processes, and reliable electrical safety in demanding industrial environments.
