Industrial TEYL3090B Bolted-On Circuit Breaker

TEYL3090B is an ABB/GE molded‑case circuit breaker, three‑pole, rated 90 A with a bolt‑on mounting suitable for grounded 480Y/277 VAC systems. It carries a 65 kA interrupting rating at 480/277 VAC, and its per‑pole width is one inch, supporting compact installation in panelboards. This bolt‑on 3P device belongs to the TEY family, a form factor commonly installed in lighting panelboards and GE A‑Series panels where high fault currents must be reliably interrupted. In industrial and commercial power distributions, the TEYL3090B protects feeders and branch circuits from overloads and short circuits while aligning with standard 480/277 VAC three‑phase systems and the bolt‑on mounting used in many distribution assemblies.
