GE TEYL3090B - 90 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The GE TEYL3090B is a 90A, 480V, 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built for enduring performance, it provides precise protection characteristics in residential, commercial, and light industrial environments.

What sets the TEYL3090B apart

• Secure bolt-on mounting creates a rigid, vibration-resistant bus connection, reducing movement that can loosen connections and affect protection reliability.
• Thermal-magnetic trip unit delivers stable, repeatable protection by combining a thermal element for overload detection with a magnetic element for short-circuit response.
• OEM-compatible design engineered to work with matching GE OEM loadcenters and panelboards for seamless integration and warranty alignment.
• Three-pole configuration (3P) is ideal for three-phase systems common in commercial and light industrial setups, providing balanced protection across all phases.
• Versatile application suited for residential, commercial, and light industrial distribution networks that demand reliable 480V protection.
