General Electrics TEY350ST12 - 50 A, 3-Pole Bolt-On Circuit Breaker | AmpState

Introducing the General Electrics TEY350ST12 — a 50A, 3-pole bolt-on molded case circuit breaker designed for dependable branch circuit protection in panelboards and loadcenters. Engineered for residential, commercial, and light industrial applications, this unit delivers steady, reliable performance when it matters most, backed by the trusted GE lineage and the AmpState promise of support and availability.

• Secure bolt-on mounting: Provides a rigid, vibration-resistant bus connection that stays aligned under normal operation and equipment movement, helping to prevent loose connections and intermittent trips.
• Thermal-magnetic trip unit: Combines thermal overload protection with magnetic short-circuit sensing for stable, repeatable protection across varying loads and temperatures, reducing nuisance trips during startup surges or peak demand periods.
• Three-pole configuration: 50A rating across three poles ensures comprehensive protection for multi-phase circuits, ideal for panelboards and loadcenters that feed balanced, higher-capacity loads.
• OEM-compatible design: Seamlessly pairs with matching GE OEM loadcenters and panelboards, simplifying replacement and service in existing installations without modification to the enclosure.
• Versatile application: Built to safeguard branch circuits in homes, offices, retail spaces, and light industrial facilities, including lighting systems, HVAC, and small motor loads.

The TEY350ST12 is a purpose-built solution for maintainers and electricians who demand consistent protection without the guesswork. Its bolt-on format is tailored for installations where a solid mechanical mount and a robust bus connection are priorities, while the 50A, 3-pole configuration provides ample headroom for common circuits in modern panelboards and loadcenters.

Key use cases include upgrading or replacing aging protection on residential subpanels, equipping small commercial distribution boards, or provisioning light industrial panels where reliable overcurrent protection is essential. When installing or upgrading, verify panel compatibility with GE OEM products and follow manufacturer torque and mounting guidelines to ensure optimal performance.

In short, the General Electrics TEY350ST12 50A, 3-Pole Bolt-On Molded Case Circuit Breaker delivers durable protection, straightforward replacement in compatible panels, and a thoughtful balance of speed and precision for everyday electrical systems—backed by GE’s engineering legacy and AmpState reliability.
