GE TED134090 - 90 A, 480 V, 3-Pole Circuit Breaker | AmpState

The GE TED134090 is a 90 amp, 480-volt, 3-pole molded case circuit breaker designed to deliver dependable branch-circuit overcurrent and short-circuit protection in panelboards and load centers. Built to integrate with GE OEM panel products, this device helps you build safe, reliable electrical distributions for commercial and industrial environments while keeping installation compact and organized.

Key advantages that matter in real-world panels

• Compact molded case design optimizes panel space, making it easier to fit into densely populated distribution boards without sacrificing protection.
• Thermal-magnetic trip unit delivers stable, repeatable protection across a range of loads and ambient conditions, helping coordinate protection for both overloads and short circuits.
• 3-pole configuration at 480V ideal for three-phase systems common in commercial and light industrial settings, providing synchronized protection across all conductors.
• OEM-compatible designed to work seamlessly with matching GE load centers and panelboards for straightforward installation and reliable performance.

Why this model matters for your electrical system

If you’re stocking a panel that serves 3-phase equipment, the TED134090 delivers precise protection where it’s most needed. The 90A rating is well-suited for protecting feeders and branch circuits that power motors, HVAC equipment, lighting banks, and other infrastructure in offices, workshops, and small manufacturing spaces. The molded case approach reduces panel depth and simplifies wiring routes, which can translate to cleaner installations and easier future maintenance or upgrades.

Ideal applications

• Commercial electrical panels powering offices, retail spaces, and data centers with 3-phase equipment.
• Light industrial panelboards that feed motors, compressors, or processing lines running on 480V.
• Residential-commercial hybrids where three-phase protection is needed without expanding panel footprint.
