GE TEYL2030B - 30 A, 480 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Engineered for dependable protection in a range of panelboard environments, the GE TEYL2030B 30A, 480V, 2-pole bolt-on molded case circuit breaker delivers reliable branch circuit overcurrent and short-circuit protection where it matters most.

With bolt-on mounting, it offers a rigid, vibration-resistant bus connection that stays put through machinery start-ups and building movement, helping reduce nuisance trips and connection wear over time.

The thermal-magnetic trip unit provides stable, repeatable protection: the thermal element responds to gradual overcurrents, while the magnetic element delivers instantaneous interruption during short circuits, helping protect wiring and equipment during fault events.

Designed to work seamlessly with matching OEM loadcenters and panelboards, this breaker is ideal for residential, commercial, and light industrial applications where 480V systems are in use and space is at a premium.

Why choose this GE breaker

Unlike generic substitutes, the TEYL2030B is built to integrate with GE's ecosystem of load centers and panelboards, ensuring coordinated protection and reliable performance in everyday commercial and light industrial settings. The 2-pole construction provides targeted protection for feeders and branch circuits, while the 30 A rating is a practical balance for many control panels and equipment suites.

Use cases and installation scenarios

• Protecting a 480 V feeder circuit in a small commercial panelboard serving HVAC equipment, lighting, and receptacles.
• Upgrading an aging panel with a bolt-on breaker designed for secure mounting in vibration-prone environments like warehouses or manufacturing spaces.
• Retrofits in residential and light industrial installations where a sturdy, OEM-compatible 2-pole breaker is required.

Practical tips

For best results, ensure the breaker lands in an OEM-compatible bolt-on slot and verify the panel rating aligns with a 480 V system. Use appropriate torque on mounting screws per GE installation guidelines and inspect the bus connection periodically in high-vibration environments to maintain optimal performance.
