GE TEYD3020B - 20 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

GE TEYD3020B is a 3-pole, 20A, 480V bolt-on molded case circuit breaker crafted to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Built for rugged environments, this device combines precise protection with solid mechanical retention to keep critical electrical systems safe and operating smoothly.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, helping to minimize movement-related wear and maintain reliable electrical contact in demanding installations.
• Thermal-magnetic trip unit delivers stable, repeatable protection performance: the thermal element responds to sustained overloads while the magnetic element provides fast disconnection during dangerous short-circuit events.
• OEM-compatible design ensures seamless integration with matching GE OEM load centers and panelboards, reducing retrofit hassles and improving overall system compatibility.
• Versatile application suitable for residential, commercial, and light industrial environments where reliable 480V protection is required for 3-phase circuits.
