General Electric TEY320 Circuit Breaker 20A 3P 480V TEY 3PH 3 Pole 20 Amp

General Electric TEY320 Circuit Breaker is a three-pole, 20-amp protection device designed for 480-volt, three-phase systems. Built to endure the rigors of industrial and commercial power distribution—and even demanding residential setups—it delivers reliable, consistent protection where you need it most.

• Three-pole, 20A, 480V rating — ensures synchronized tripping and balanced protection across all phases in 3PH 480V circuits.
• TEY family compatibility — a practical choice for panel upgrades, retrofit projects, and maintenance replacements, keeping GE-based installations cohesive and easier to source.
• Ideal for service, retrofit, and MRO stocking — a dependable component electricians and panel builders rely on for quick, effective replacements and downtime reduction.
• Robust, industrial-grade reliability — engineered to perform under demanding conditions in electrical rooms, manufacturing lines, and commercial facilities.

Designed use cases and scenarios

• Panel upgrades where a reliable 3P breaker is needed to protect new 480V feeders or downstream equipment.
• Retrofit projects across industrial, commercial, and high-demand residential environments requiring a GE TEY-series solution.
• Maintenance replacement in busy facilities where stocking a trusted GE part minimizes downtime and keeps systems protected.

Practical guidance for installation and operation

• Confirm compatibility with your GE TEY panel and ensure the system voltage matches 480V 3-phase requirements before installation.
• Match the circuit load to the 20A rating to maintain proper protection without nuisance tripping.
• Follow standard lockout/tagout procedures during servicing and replace only with the same TEY320 model to preserve protection coordination.
