General Electrics TKMA31200WL - 1200 A, 3-Pole Circuit Breaker | AmpState

The General Electrics TKMA31200WL is a rugged 1200A, 3-pole molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and load centers. Built for demanding electrical environments, this device combines compact sizing with robust performance to keep your power distribution clean and safe.

Key features

• Compact molded case design maximizes panel space without compromising protection or easy accessibility.
• Thermal-magnetic trip unit provides stable, repeatable protection by handling overloads thermally and short circuits magnetically for fast fire- and fault-clearing action.
• 3-pole configuration ensures simultaneous disconnection across all phases, reducing arc risk in 3-phase systems.
• High current rating at 1200A makes it suitable for large feeders and high-demand circuits in commercial or light industrial settings.
• OEM compatibility designed to work with matching OEM load centers and panelboards for a reliable, integrated installation.

Why this breaker stands out

In busy electrical rooms, space and reliability matter. The TKMA31200WL delivers both: a compact form factor that preserves panel compartment space, and a thermal-magnetic trip system that responds consistently under varying loads and temperatures. Its 3-pole design means you’re protected across all live conductors in a 3-phase setup, helping you avoid uneven trips that can occur with single- or two-pole devices.

Applications and compatibility

• Residential, commercial, and light industrial electrical installations requiring solid branch circuit protection.
• Panelboards and load centers that specify a 3-pole, high-current molded case breaker.
• Systems needing a dependable protection device that pairs with OEM equipment for streamlined replacement and maintenance.
