GE TEYD3090B - 90 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

GE TEYD3090B is a 90A, 480V, 3-pole bolt-on molded case circuit breaker designed to protect your electrical system from overcurrent and short circuits. Built for reliable performance in panelboards and loadcenters, it ensures quick, decisive interruption when issues arise, keeping equipment and occupants safe.

• Bolt-on mounting: secure, rigid bus connections that resist vibration and maintain consistent electrical contact.
• Thermal-magnetic trip unit: combines thermal and magnetic sensing for stable, repeatable protection across temperature and load variations, with fast response to short circuits.
• OEM compatibility: engineered to drop into matching GE OEM panelboards and loadcenters without adapters, simplifying retrofits and upgrades.
• Three-pole design: supports three-phase circuits (3-pole) for balanced protection in commercial and industrial environments.
• 90A, 480V rating: appropriate for mid-sized branch circuits operating at 480V within residential, commercial, and light industrial settings.
• Molded case construction: durable housing designed to withstand the rigors of daily electrical distribution tasks.

Applications and use cases

• Protect branch circuits in panelboards and loadcenters from overcurrent and short-circuit events.
• Ideal for commercial electrical rooms, light industrial equipment setups, and retrofit projects where a 3-phase, 480V supply is used.
• Suitable for new installations and panel upgrades that require a reliable 3-pole 90A breaker with firm, vibration-resistant mounting.
