GE TEYD1020B - 20 A, 480 V, 1-Pole Bolt-On Circuit Breaker | AmpState

Meet the GE TEYD1020B—a purpose-built, 20A, 480V, 1-pole bolt-on molded case circuit breaker designed to protect individual branch circuits with unwavering reliability. Built for panelboards and load centers, this breaker delivers precise, dependable overcurrent and short-circuit protection where it matters most.

• Secure bolt-on mounting: a rigid, vibration-resistant bus connection that stays tight through the stresses of panel operation and equipment start-up for long-term electrical integrity.
• Thermal-magnetic trip unit: combines a precise thermal element for overload protection with a fast magnetic trip for short-circuit events, delivering stable, repeatable protection performance across varying loads and environments.
• OEM-compatible design: engineered to be compatible with matching GE OEM load centers and panelboards, ensuring proper fit, coordination, and reliable operation within established electrical systems.
• Versatile application: ideal for residential, commercial, and light industrial settings where single-pole protection on a 480V circuit is required—supporting lighting, control circuits, small equipment, and other branch circuits.

Technical snapshot

• GE
• Part number: TEYD1020B
• Type: Thermal-magnetic molded case circuit breaker
• Amperage rating: 20 A
• Voltage rating: 480V
• Number of poles: 1
• Mounting style: Bolt-on

Why this matters in practice: in busy electrical panels, a secure bolt-on connection minimizes vibration-induced loosening, while the thermal-magnetic trip responds quickly to faults, helping prevent damage to wiring, devices, and downstream equipment. The 480V rating makes it suitable for commercial and light industrial environments that operate higher-voltage branch circuits, delivering targeted protection where you need it most.

Who benefits from the GE TEYD1020B:

• Electrical contractors installing or upgrading panelboards in commercial spaces and light industrial facilities.
• Facilities managers looking to ensure reliable protection for 480V circuits on specific loads or control circuits.
• HVAC technicians and electricians wiring dedicated branch circuits that require solid, predictable interruption behavior.

Practical tips for optimal use:

• Pair with matching GE OEM load centers and panelboards to guarantee fit and electrical coordination.
• Use in applications where single-pole protection on a 480V line is appropriate within a multi-circuit panel—verify the surrounding protection scheme for code compliance.
• Schedule periodic inspections of bolt-on connections in vibration-prone environments to maintain a secure bus connection over the lifespan of the panel.

Engineered for reliability, compatibility, and clear protection—the GE TEYD1020B is a dependable choice for safeguarding your 480V circuits while delivering straightforward installation and trustworthy performance in demanding panel environments.
