GE TEYH3090B - 90 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the GE TEYH3090B — a 90A, 480V, 3-pole bolt-on molded case circuit breaker designed to protect your panelboards and loadcenters with precision and reliability. Built for real-world electrical environments, this device delivers dependable branch circuit overcurrent and short-circuit protection where it matters most.

Why this bolt-on 3-pole breaker stands out

Secure bolt-on mounting provides a rigid, vibration-resistant bus connection. In environments subject to mechanical vibration, temperature cycling, or equipment operation, that solid connection helps maintain consistent electrical performance and minimizes the risk of loose contacts over time.

Thermal-magnetic trip unit offers stable, repeatable protection across a wide range of temperatures and load conditions. The dual mechanism responds to both sustained overcurrent and instantaneous short-circuit events, helping safeguard wiring and devices downstream without nuisance trips.

Designed for compatibility with matching OEM loadcenters and panelboards, this breaker integrates seamlessly into GE-based systems and altrec hardware designed to accept bolt-on molded case breakers. It’s a dependable choice for residential, commercial, and light industrial applications where robust 3-phase protection is required.
