GE TED134020 - 20 A, 480 V, 3-Pole Circuit Breaker | AmpState

The GE TED134020 is a compact 3-pole molded case circuit breaker rated at 20A and 480V, engineered to deliver dependable branch circuit protection in panelboards and load centers. Its streamlined, space-efficient design helps you maximize panel real estate without compromising protection for three-phase circuits.

• Thermal-magnetic trip unit: Combines overload protection (thermal) with fast short-circuit interruption (magnetic) for stable, repeatable performance across varying temperatures and load conditions.
• Space-saving molded case design: Optimizes panel layout, making it easier to fit into dense panelboards and load centers common in commercial and light industrial settings.
• OEM panel compatibility: Specifically designed to pair with matching GE OEM load centers and panelboards, ensuring reliable fit and electrical coordination.
• Versatile application: Suitable for residential, commercial, and light industrial environments where strict overcurrent and short-circuit protection is essential.
• Three-pole, 480V operation: Ideal for 3-phase distribution systems, delivering precise protection where 480V service is standard.
