GE TED124040 - 40 A, 480 V, 2-Pole Circuit Breaker | AmpState

GE TED124040 40A, 480V, 2-pole molded case circuit breaker is engineered to shield panelboards and loadcenters from overcurrent and short-circuit faults with dependable, predictable performance.

What makes this breaker stand out

• Compact molded-case design optimizes panel space, letting you fit more circuits into the same enclosure without crowding.
• Thermal-magnetic trip unit delivers stable, repeatable protection: the thermal element handles slow, steady overcurrents, while the magnetic element delivers an instantaneous trip on severe faults.
• OEM panel compatibility is designed to drop into matching GE load centers and panelboards for straightforward replacement and reliable operation.
• Versatility for multiple settings suitable for residential, commercial, and light industrial applications that require 480V distribution and solid branch-circuit protection.

Why this breaker helps you manage electrical systems more reliably

In industrial or commercial panels, a compact two-pole 40A solution that fits neatly into GE panelboards reduces installation complexity while maintaining strong protection for motor loads, lighting circuits, or other 480V feeders. The combination of a molded-case design with a thermal-magnetic trip means you get precise protection characteristics, repeatable tripping behavior, and fast response to short circuits—so equipment downtime is minimized and downstream wiring stays safeguarded.

Ideal use cases

• Upgrading or replacing a failed breaker in a GE OEM load center or panelboard
• Protecting 480V distribution circuits in light industrial or commercial environments
• Providing reliable branch-circuit protection for motors, HVAC equipment, or large electrical loads in panel installations

Practical best-practices and tips

• Always verify compatibility with your GE panelboard series before installation to ensure a proper fit and bus alignment.
• Power should be shut off and the panel briefly discharged before removing or installing a breaker; follow lockout/tagout procedures as required.
• Use the 2-pole 40A rating for circuits expected to draw up to 40A under normal operation, with the thermal-magnetic trip handling any overloads and short circuits.
• Keep spare TED series breakers on hand for quick field replacement in maintenance schedules to minimize downtime.
