GE TEYH3015B - 15 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the GE TEYH3015B from AmpState—a 15A, 480V, 3-pole bolt-on molded case circuit breaker built to safeguard panelboards and load centers with precision and reliability. Designed for residential, commercial, and light industrial applications, this unit delivers dependable branch circuit overcurrent and short-circuit protection in a compact, field-installable package.

Secure bolt-on mounting for rock-solid reliability

The bolt-on mounting design creates a rigid, vibration-resistant bus connection, reducing the risk of loose contacts and intermittent trips in demanding environments. Whether installed in a busy commercial panel or a compact industrial control cabinet, TEYH3015B stays firmly seated, ensuring consistent protection without the wobble that can compromise performance over time.

Thermal-magnetic trip unit for stable, repeatable protection

Equipped with a thermal-magnetic trip mechanism, this breaker delivers predictable, repeatable response to overcurrent conditions. The thermal element handles gradual heating while the magnetic element snaps into action for instantaneous short-circuit events, helping protect conductors and connected equipment from damage and reducing nuisance trips in systems with motor start-ups or surge activities.

3-pole design at 480V for versatile, three-phase protection

With 3 poles, 15A rating, and a 480V operating capability, TEYH3015B is well-suited for three-phase distribution in commercial spaces and light industrial setups. It provides reliable protection for branch circuits feeding motors, lighting, and control equipment while aligning with standard GE and OEM panelboard architectures.

OEM-compatible and easy retrofit

Designed to be compatible with matching GE OEM load centers and panelboards, this breaker integrates smoothly into existing installations. Its exacting fit and trip characteristics help ensure seamless replacement or upgrade paths without compromising electrical safety or panel labeling.

Ideal use cases

• Upgrading or replacing breakers in GE-compatible panelboards and load centers within small to mid-size commercial spaces.
• Protecting branch circuits that serve lighting, receptacles, and modest motor loads in offices, schools, retail spaces, and light industrial facilities.
• Retrofit projects where a reliable, bolt-on, 3-pole protection device is required for 480V distribution systems.
• New installations in environments where vibration resistance and robust mounting are priorities—workstations, equipment rooms, and mechanical spaces.
