GE TED134040 - 40 A, 480 V, 3-Pole Circuit Breaker | AmpState

GE TED134040 is a 40A, 480V, 3-pole molded case circuit breaker engineered to deliver dependable branch circuit protection and rapid short-circuit response in panelboards and load centers. Built for real-world efficiency, it fits seamlessly into GE-compatible OEM panels, helping you maintain consistent electrical protection across your installation with fewer part mismatches.

Why this breaker stands out

• Space-efficient molded case design: The compact footprint maximizes panel enclosure space, allowing for smarter layout in both commercial and residential settings where panel real estate matters.
• Thermal-magnetic trip unit: Combines thermal overload protection with instantaneous magnetic trip for stable, repeatable protection performance against overcurrents and short circuits.
• 3-pole construction for 480V systems: Specifically suited to three-phase, 480V electrical environments common in commercial and light industrial applications, delivering coordinated protection for 3-phase feeders.
• OEM-compatible: Designed to pair with matching GE OEM load centers and panelboards, ensuring proper fit, electrical characteristics, and a straightforward replacement experience.
• Clear specification alignment: Rated for 40A at 480V with three poles, this device provides reliable protection for branch circuits feeding motors, transformers, and other 3-phase equipment.

Where it shines

Ideal for commercial buildings, light industrial facilities, and select residential projects that employ 3-phase 480V distribution. Use cases include safeguarding 3-phase motor loads (pumps, compressors, conveyors), feeder circuits to electrical equipment rooms, and panelboard branch circuits that require precise current limitation and fast short-circuit disconnection. With its robust thermal-magnetic protection, you gain predictable responses across varying load conditions, reducing nuisance trips while maintaining safety.

Practical guidance and best uses

• Pair this 3-pole 40A breaker with compatible GE panels in networks where 480V three-phase distribution drives critical equipment. Map protection to the circuit’s load profile to minimize unnecessary outages.
• Use only in GE-certified panelboards/load centers designed for 480V three-phase operation. Follow the panel’s documentation for the correct taping, bus compatibility, and replacement procedure.
• From busy commercial spaces to light industrial floors, this breaker maintains dependable protection without demanding extra space, helping maintenance teams streamline inventory and replacements.
• Keep a small stock of TED134040-style breakers on hand for quick swaps when protection devices require renewal, reducing downtime in critical systems.
