GE TEYH3030B - 30 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the GE TEYH3030B—a 30A, 480V, 3-pole bolt-on molded case circuit breaker built to protect your distribution system with precision. Designed for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers, this unit delivers reliable performance where it matters most.

• Secure bolt-on mounting for a rigid, vibration-resistant bus connection. Engineered to stay tight through thermal cycling and equipment vibration, reducing contact wear and ensuring consistent protection.
• Thermal-magnetic trip unit combines time-delayed thermal protection with instantaneous magnetic tripping for fast response to severe faults. Expect stable, repeatable protection curves that guard motors, lighting, and other critical loads from both overloads and short circuits.
• OEM-ready compatibility designed to pair with matching GE OEM load centers and panelboards, ensuring a seamless fit, streamlined installation, and validated electrical performance.
• Versatile, robust protection suitable for residential, commercial, and light industrial applications where a reliable 3-phase, 480V distribution solution is required.

Use cases and practical benefits

Designed for three-phase distribution, the TEYH3030B excels in panelboards and load centers powering commercial spaces, light industrial facilities, and multi-muite motor setups. Examples include:

• Protecting 3-phase motors on manufacturing lines where reliable trip behavior minimizes downtime.
• Distributing power to lighting and receptacle circuits in small to mid-size commercial buildings with 480V systems.
• Serving as a sturdy, maintainable protection point in refurbished or retrofitted panel racks that require a bolt-on MCCB solution.

Why choose this GE breaker over alternatives

This TEYH3030B emphasizes durability and consistent protection in demanding environments. The bolt-on design provides a more rigid connection than plug-in styles, reducing the risk of loose contacts during vibration or heavy loads. The integrated thermal-magnetic trip unit offers predictable performance across a range of fault conditions, so you know exactly how the protection will respond when faults occur. When paired with GE OEM load centers and panelboards, you get a cohesive, validated protection system with proven reliability.

Guidance for optimal results

• Confirm system voltage and phase configuration matches a 480V, 3-pole setup to ensure correct trip characteristics and coordination with downstream protection devices.
• Use with compatible GE panelboards to maintain accurate trip curves and electrical clearance requirements.
• Keep connections clean and torqued to manufacturer specifications to preserve the reliability of the bolt-on mounting.
