GE TEYH3050B - 50 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Introducing the GE TEYH3050B — a 50 A, 480 V, 3-pole bolt-on molded case circuit breaker crafted to protect your electrical system with dependable, real-world performance. Designed for use in panelboards and load centers, this unit delivers precise overcurrent and short-circuit protection where it matters most.

Why this breaker stands out in the field is the combination of secure mounting, reliable trip technology, and panel compatibility that installers trust. The secure bolt-on mounting creates a rigid, vibration-resistant bus connection, minimizing movement and arcing that can jeopardize circuit integrity in demanding environments. Its thermal-magnetic trip unit combines a thermal overload element with a magnetic short-circuit trip to deliver stable, repeatable protection across a range of fault conditions.

Key benefits

• Secure bolt-on mounting: A robust, vibration-resistant connection that stays put through the life of the panel, reducing the risk of connection-related faults.
• Thermal-magnetic protection: The thermal element handles steady overloads, while the magnetic switch provides instantaneous response to severe short circuits for rapid isolation.
• OEM-friendly compatibility: Designed to pair with matching GE OEM load centers and panelboards, helping streamline installation and maintenance.
• Versatile application range: Suitable for residential, commercial, and light industrial installations that require reliable 3-pole protection at 480 V.

Use cases and practical scenarios

Ideal for new constructions or retrofit projects where a sturdy 3-pole 50 A protection device is needed at 480 V. Consider deploying the GE TEYH3050B in:

• Commercial panelboards feeding office lighting and power circuits in warehouses or retail spaces.
• Industrial distribution panels protecting small machinery and equipment suites in light fabrication or processing environments.
• HVAC and mechanical rooms where dependable protection against overloads and faults is critical for uptime.
